Hybrid Biodegradable Films from Collagenous Wastes and Natural Polymers for Biomedical Applications

Abstract

Biopolymeric films have been the focus of research for the past few decades because they offer favorable advantages compared to synthetic polymeric films in the field of biomedical engineering. In this study, collagen (C) was extracted from skin waste using acetic acid and blended with starch (ST)/soy protein (SP) to prepare C/ST/SP hybrid films. The prepared hybrid films were examined for biocompatibility, physical and chemical properties. The results demonstrated that the strength properties of hybrid films increase as the composition of starch increases while elongation increases as the composition of soy protein increases. Thermogravimetric analysis of select hybrid films showed that the..
