Abstract

This study reports the fabrication of PVA/PVP/vanillin blend films by using solvent casting method. The objective of this study was to investigate the correlation between PVA/PVP/vanillin blend films of different weight ratio, mechanical properties and thermal properties. The PVA/PVP/vanillin blend films were subjected to the mechanical study and thermo gravimetric analysis. Addition of PVP/vanillin has significant effect on PVA films, exhibiting decreased tensile strength and young’s modulus. The tensile strength of blend films is lower compare to the pure PVA film. Results obtained from thermal analysis indicate that all the components in the blend films are miscible showing single glass transition temperature and are stable up to 185oC suggesting that, a considerable amount of interactions may exist between components in each blend films.
