The Degradation of Poly (Vinyl Alcohol)/Chitosan Blend Membranes with Introduction to Silk Sericin
Chitosan is a natural amino polysaccharide and has perfect biocompatibility and antibacterial function with broad-spectrum.Variational characteristics of glutinosity in chitosan/ acetic acid gel polymer blending with a certain concentration of polyvinylalcohol (PVA) in different condition were measured.Sericin is soluble polypeptide macromolecular compound dissolving in warm water,being high chemical characteristics,and having some kinds of necessary amino acids,high moisture permeability,high moisture retention and with better human affinity,people can use the mixture blending silk sericin with PVA and chitosan to manufacture valuable composite materials.In the experiment,the degradation of the mixture membrane in simulated body fluid (SBF) was measured.The results showed that the speed of degradation of the film can be adjusted by using different concentration of PVA and chitosan and/or sericin.
