Preparation of semirigid polyurethane foam with liquefied bamboo residues
Authors: Gao Long‐Lan , Liu Yu‐Huan , Lei Hanwu , Peng Hong , Ruan Roger 
Published: January 2010

AbstractBamboo residues were liquefied by using a solvent mixture consisting of polyethylene glycol 400 and crude glycerol (4/1, w/w) with 98% sulfuric acid as catalyst at 160°C for 120 min. The liquefied bamboo had hydroxyl values from 178 to 200 mg KOH/g and viscosities from 507 to 2201 mPa S. The obtained bamboo‐based polyols were reacted with various amounts of polyaryl polymethylene isocyanate (PAPI), using distilled water as blowing agent, silicone as surfactant, and triethylenediamine and dibutyltine dilaurate as cocatalyst to produce semirigid polyurethane (PU) foams. The [NCO]/[OH] ratio was found to be an important factor to control the mechanical properties of PU foams. At a fixed [NCO]/[OH] ratio, both density and compressive strength of PU foams decreased with the increase of bamboo content. The microstructure of PU foams indicates that [NCO]/[OH] ratios are important for cell formation and chemical reactions. The uniformity and cell structure of the foams are comparable to their corresponding compressive strengths. Moreover, the thermogravimetry analysis showed that all the semirigid PU foams had approximately the same degradation temperature of about 250 to 440°C. © 2010 Wiley Periodicals, Inc.

Structure and properties of high melt strength polypropylene prepared by combined method of blending and crosslinking
Authors: An Yanjie , Zhang Zhenjiang , Wang Yanhui , Qiu Jian , Tang Tao 
Published: January 2010

AbstractHigh melt strength polypropylene (HMSPP) was prepared by in situ heat induction reaction, in which pure polypropylene (PP) powders without any additives was used as basic resin, and low density polyethylene (LDPE) and trimethylolpropane triacrylate (TMPTA) were added as blending resin and as crosslinking agent, respectively. Microstructure of the obtained HMSPP (PP/LDPE/TMPTA blends) was characterized by FTIR, Wide‐angle X‐ray diffraction (WAXD), and testing of gel content. The effect of LDPE content on melt strength and melt flow rate of HMSPP were investigated. When the content of LDPE was 40 wt %, the melt strength of the HMSPP was above 16 CN, which was much higher than those of pure PP powder (2.6 CN) and PP/LDPE blends without TMPTA (6.1 CN). Moreover, thermal behavior and mechanical properties of the HMSPP were also investigated. The results showed that the thermal stability and impact strength of HMSPP were greatly improved. In addition, HMSPP possessed good processing performance and good foaming properties. The foams produced by HMSPP showed uniform, closed, and independent cells. © 2010 Wiley Periodicals, Inc.

Novel biodegradable form stable phase change materials: Blends of poly(ethylene oxide) and gelatinized potato starch
Authors: Pielichowska Kinga , Pielichowski Krzysztof 
Published: January 2010

AbstractNovel biodegradable form stable phase change materials were obtained in a process involving potato starch gelatinization in water/poly(ethylene oxide) (PEO) solution. DSC and microscopic investigations revealed that the presence of the starch considerably changes PEO phase transition behavior–in the blends solid–solid phase transition for PEO/starch 1 : 3 and 1 : 1 w/w has been observed; for PEO/starch blend 3 : 1 w/w solid–solid phase transition with a partial melting of PEO unbounded through hydrogen bonds with starch has been detected. The heat of phase transition depends on the strength of hydrogen bonds between PEO and starch. The intermolecular interactions were evidenced by FTIR analysis, which showed considerably shift of the stretching vibration bands of both the OH group (proton‐donor group) from starch and PEO. © 2010 Wiley Periodicals, Inc.

Droplet size and morphology for the aqueous two‐phase polymerization of acrylamide in an aqueous poly(ethylene glycol) solution
Authors: Lü Ting , Shan Guo‐Rong 
Published: January 2010

AbstractA kind of polyacrylamide (PAM) latex product dispersed in an aqueous solution was successfully prepared through the aqueous two‐phase polymerization of acrylamide in an aqueous solution of poly(ethylene glycol) (PEG). The effects of various polymerization parameters on the size and morphology of droplets rich in PAM were systematically investigated. The droplet size and morphology was significantly influenced by the polymerization rate. The high polymerization rate caused the formation of stripe‐shaped droplets because of the aggregation of more droplets rapidly separated from the continuous phase. At the same time, the monomer partition behavior mainly relied on the temperature, and the PEG concentration also dramatically affected the droplet size and morphology. The increase in PEG concentration not only changed the monomer partition behavior and restrained droplet aggregation but also shortened the critical PAM radical chain length and accelerated the droplet formation. Furthermore, the stirring speed was also recognized as the correlative factor that affected the droplet stability and monomer diffusion rate from the continuous phase into the droplets. The addition of salt and alcohol altered the droplet stability and the final droplet size and morphology. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
Fibrous membranes of cellulose acetate and poly(vinyl pyrrolidone) by electrospinning method: Preparation and characterization
Authors: Castillo‐Ortega M. M. , Romero‐García J. , Rodríguez F. , Nájera‐Luna A. , Herrera‐Franco P. J. 
Published: January 2010

AbstractFibrous membranes of cellulose acetate (CA), poly(vinyl pyrrolidone) (PVP) and composite membranes of these polymers, were obtained by the electrospinning method. Using systematic method, the optimal conditions for preparation of fibrous membranes were found. Both CA and PVP a concentration of 8% weight was found. The CA was dissolved in a acetone:water solution, volume ratio 80 : 20 and the PVP is dissolved in ethanol:water solution, ratio volume 85 : 15. The flow rate for both polymers was 1.5 mL h−1. The same applied voltage value and the distance between the needle and collection plate were for polymer both, 15 kV and 15 cm respectively. The morphology of fibrous membranes and composite membranes were evaluated by scanning electron microscopy (SEM). The CA fibers showed ribon morphology, while the PVP fibers were cilindric, in both cases with diameters in the micrometer range. Thermogravimetric analysis showed that CA had a complete degradation to 445°C, while the fibrous membranes PVP required a value of temperature for degradation of up to 571°C. Fibrous composite membrane PVP/CA/PVP shows a higher value of strain at break (%), and a lower value of tensile strength (MPa) compared to CA/PVP/CA. © 2010 Wiley Periodicals, Inc.

Mechanical properties of polypropylene composite reinforced with oil palm empty fruit bunch pulp
Authors: Tay G. S. , Zaim J. Mohd. , Rozman H. D. 
Published: January 2010

AbstractIn this study, oil palm empty fruit bunch (EFB) pulp was used as reinforcing agent in polypropylene composite. EFB pulp was prepared using soda pulping with different concentrations of sodium hydroxide (NaOH) solution. Overall, the tensile and flexural properties specifically the strength and the toughness showed improvement as the NaOH content in the treatment was increased. This was attributed to lower probability for EFB pulp to agglomerate and the production of higher aspect ratio pulp fibers. Scanning electron microscopy analysis showed evidence of the reduction in EFB bundles diameter after NaOH treatment. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
Carbon nanotube‐hybridized supramolecular hydrogel based on PEO‐b‐PPO‐b‐PEO/α‐cyclodextrin as a potential biomaterial
Authors: Hui Zhongying , Zhang Xiaolan , Yu Jiahui , Huang Jin , Liang Zhongshi , Wang Daxin , Huang Haitao , Xu Peihu 
Published: January 2010

AbstractIn virtue of the potential biomedical application of carbon nanotube (CNT), the CNT was hybridized into a supramolecular hydrogel based on the selective inclusion of α‐cyclodextrin (α‐CD) onto poly(ethylene oxide) (PEO) segments of a triblock copolymer, i.e., PEO‐block‐poly(propylene oxide)‐block‐PEO. Different from the previous report, the content of α‐CD, in contrast to that of ethylene oxide unit, was decreased to decrease the network density in hydrogel and hence improve the diffusion of encapsulated substances. As a result, the modulus of the hydrogels climbed slightly after introducing CNT. Furthermore, as the essential properties for wound dressing, the antimicrobial activity, the skin‐adhesion, and water‐retention of such supramolecular hybrid hydrogels were also verified. On the other hand, the supramolecular hybrid hydrogels inherited the shear‐thinning property and are suitable as an injectable biomaterial. The cell viability assay confirmed the equivalent cytotoxicity of the supramolecular hybrid hydrogels to that of the native hydrogels without CNT. Consequently, such CNT‐hybridized supramolecular hydrogel shows a great potential in the biomedical application. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
Self Report of Negative Parenting Styles, Psychological Functioning and Risk of Negative Parenting by One Parent being Replicated by the Other in a Sample of Adolescents aged 13–15
Authors: Ritchie Charlotte , Buchanan Ann 
Published: January 2010

AbstractThis study, which used a community sample of 13–15 year old adolescents (N = 391), sought to establish the extent to which negative parenting styles are linked to increased likelihood of abnormal psychological functioning in young people, and the likelihood of negative parenting by one parent being replicated by the other. Findings suggest that negative parenting styles are significantly correlated with raised scoring on the Strengths and Difficulties Questionnaire, and that particular negative parenting styles in one parent are likely to be found in the other. The high percentages of young people reporting parents being often angry, sometimes frightening and lacking in warmth and affection give rise to concern about the facilitation of parenting in the UK.

Impact of Organic Interlayer Anions in Hydrotalcite Precursor on the Catalytic Activity of Hydrotalcite‐Derived Mixed Oxides
Authors: Meyer Oliver , Roessner Frank , Rakoczy Rainer A. , Fischer Richard W. 
Published: January 2010

AbstractA series of hydrotalcite‐derived mixed oxides containing different organic interlayer anions in the hydrotalcite precursors have been synthesized and studied as catalysts in the transesterification of glycerol trioctanoate with methanol. There are significant differences in the catalytic activity of these mixed oxides, indicating a great impact of interlayer anions in hydrotalcite precursors. Generally, anions with high charge density and, therefore, high content within the interlayer of the hydrotalcites lead to higher catalytic activity in the derived mixed oxides in contrast to anions with low charge density. An influence of interlayer anions on the structural properties of the hydrotalcites, such as interlayer distance, which is determined by X‐ray diffraction analysis, and on the surface area and pore volume of the corresponding mixed oxides, which are determined by nitrogen adsorption, is obtained. Furthermore, interlayer anions had a significant effect on the thermal stability of the hydrotalcite structure as well as on the pore size distribution of derived mixed oxides.
