Abstract

Over the past decades, a lot of researches have been made in the development of many hybrid materials, to obtain new materials for new applications. In particular, some natural and synthetic polymers combined with using different methods [i][ii][iii]. Gelatin-polystyrene based hybrid materials have been studied to change some properties of polymers such as mechanical properties and biocompatibility. In this work, Gelatin-polystyrene based hybrid material was synthesized through photopolymerization type II. An alternative method was applied for preparing gelatin-polystyrene copolymer by using gelatin as a macroinitiator and benzophenone as a co-initiator. The polymerization of styrene on gelatin was carried out based on the hydrogen abstraction of type II photoinitiator from free amine groups (-NH2) of gelatin. After the polymerization, the chemical structure of the copolymer was analyzed by FTIR spectroscopy and wettability and hydrophilicity were determined by water contact angle measurements.
