The Preparation of Chitosans Membranes with Different Molecular Weight
摘要
Abstract
Objective Growth factors are used to accelerate osseous integrations. Usually, growth factors are destroyed easily and fixed difficultly in oral implantology area. The aim of this study was to prepare chitosans membrane with different molecular weight, and provide evidence for the application of chitosans in oral implants. Method Chitosans membranes and gelatin-chitosans membranes were prepared with chitosans with different molecular weight (3 000, 100, 000, 200, 000, 450, 000) by solvent evaporation method. Results Chitosans with all different molecular weight could be prepared to chitosans membranes. The addition of gelatin didn't affect the preparation of chitosans membranes with chitosans with high molecular weight. When preparing low molecular weight chitosan membranes, the addition of gelatin and glycerin was necessary. Conclusion The preparation of chitosans membranes is related with the molecular weight and the addition of excipients.关键词
