Preparation and Characterization of Complex Membrane from Poly vinyl Alcohol and Collagen Fiber

摘要

In this paper, PVA/Collagen complex membrane was successfully prepared from polyvinyl alcohol and collagen fibers. The characterization of mechanical properties, swelling ratio, Differential Scanning Calorimetry (DSC), Differential Scanning Calorimetry (SEM) and X-ray diffraction for the complex membranes were carried out. The effects of different blending ratios on the overall performance of the complex membranes were mainly discussed. As a result, the suitable blending ratios were determined. Under such conditions, polyvinyl alcohol has good compatibilities with collagen. The complex membranes exhibit relatively high uniformity, transparence and strength as well as small swelling ratio and high heat-resistant properties and thus have a bright prospect of application.
