UNASSIGNED: In this study, hybrid @entity6638 /cellulose nanowhiskers ( @entity569 /CNW) reinforced @entity7049 ( @entity1989 ) nanocomposites were produced through solution casting. The CNW filler was first isolated from microcrystalline cellulose by chemical swelling technique. The partial replacement of @entity569 with CNW in order to produce @entity1989 / @entity569 /CNW hybrid nanocomposites was performed at 5 parts per hundred parts of polymer (phr) fillers content, based on highest tensile strength values as reported in our previous study. @entity569 were partially replaced with various amounts of CNW (1, 2, 3, 4 and 5phr). The tensile, thermal, morphological and biodegradability properties of @entity1989 hybrid nanocomposites were investigated. The highest tensile strength of hybrid nanocomposites was obtained with the combination of 4phr @entity569 and 1phr CNW. Interestingly, the ductility of hybrid nanocomposites increased significantly by 79% at this formulation. The Young's modulus increased linearly with increasing CNW content. Thermogravimetric analysis illustrated that the partial replacement of @entity569 with CNW filler enhanced the thermal stability of the @entity1989 . This is due to the relatively good dispersion of fillers in the hybrid nanocomposites samples as revealed by transmission electron microscopy. Interestingly, partial replacements of @entity569 with CNW improved the biodegradability of hybrid nanocomposites compared to @entity1989 / @entity569 and neat @entity1989 .
