Abstract
Starch–polyvinyl alcohol blends with enhanced properties are achieved with cross-linking it with boric acid. These blends are characterized by FTIR and DSC. A film of starch and PVA blends were prepared by casting on glass plate. The effects of various factors such as increasing starch content, increasing amount of boric acid, on the performance properties like tensile strength, pencil hardness and thermal properties like glass transition temperature were studied. The results showed that the starch–polyvinyl alcohol films prepared by boric acid cross-linking had excellent mechanical, thermal properties and hardness of the film.
