Studies on the Characterisation of Poly blend- Nanofilms of Cellulose Acetate and Poly Styrene

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 cellulosic, non-toxic, non-allergic
biocompatible, biodegradable, hydrophilic, soft, smooth, transparent, highly flexible, good chemical
resistant, thermoplastic moulding material, it is used in industrial, biochemical and biomedical
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. The present investigation indicates the compatibility of Polymer
blends may be studied by SEM and Mechanical analysis. It is clear that there is a distinct phase
separation in the membranes at compositions of 50:50 of Poly styrene-Cellulose acetate. Poly
styrene-Cellulose acetate blends show maximum values of stress and tensile strength at higher
concentration of cellulose acetate.
