Abstract
The aim of present research work was to bio-modulate Poly (vinyl alcohol)/Starch (PVA/S) polymers and synthesize compositebased
PVA/S hybridised films incorporated with ZnO, TiO2
and gelatin protein hydrolysate (GPH) components. The prepared
PVA/S based composite hybridised films were characterized for physico-chemical, thermal and structural characterisation using
Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM), Thermal gravity analysis (TGA), and
X-ray diffraction (XRD) analyses. Notably, the incorporation of composites has made certain physico- chemical and structural
modifications but not altered the molecular structure of biopolymer as revealed by FTIR analysis. The gelatinized blends of
PVA/S based hybridised composite films incorporated with ZnO, TiO2
and GPH components have shown better thermal stability and
miscibility as revealed by thermal gravity analysis. The biocompatibility was investigated by evaluating viability of L929
fibroblast cell, which had good biocompatibility and was non-toxic in nature. These PVA/S based composite hybridised
films could be implemented in therapeutic biomedical research and food industrial applications.
