Characterisation of Polyblend-Nanofilms of Cellulose Acetate and Polystyrene

Abstract

Nanotechnology has potential to create many new materials and devices with wide range of applications in medicine, electronics and energy production etc. Blending technique is applied for production of new polymeric materials. As cellulose acetate is thermoplastic moulding material, it is used in industrial and biochemical applications. In the present investigation, SEM and mechanical analysis of cellulose acetate and polystyrene nano films have been studied in accordance with the change in composition of polymer over a wide range of concentrations and temperatures. Super plasticity has been observed at low temperatures and at higher strain rates in nano crystalline materials. Mechanical properties of cellulose acetate and polystyrene nano films have been studied. Phase morphology of nano membranes have been studied by SEM. SEM studies were also performed to estimate pore size distribution of the support polymer. Nano structured ceramics readily interact with bone cells and have been applied as implant materials.
