The TGA trace of the nanocomposites suggests an improvement of the thermal properties. The traces are different in nitrogen and air. The disordered dispersion of the silicate has caused a wide spread effect on the barrier characteristic of the silicate. All burning tests are done by igniting the sample with a propane It is observed that the while burning, the pure PMMA burned out completely with the melt dripping. The other mechanical properties have also increased to an appreciable extent.
Biodegradable polymers have important medical and other commercial applications.
However, the barrier properties, thermal and mechanical properties of such polymers limit their applicability. The XRD measurements suggest, both the nanocomposites are intercalated, also observed from the TEM photographs. The DSC studies reveal some interesting situation for all the nanocomposite. The thermal stability of the nanocomposites has increased a lot over the pure polymer. The dynamic mechanical properties also show that one of the nanocomposite has higher modulus.
