METHODS: Fresh bovine tendo calcaneus collagen was dispersed in 0.5 mol/L acetic acid, co-precipitated with chitosan and lyophilized. Dry membranes were cross-linked in 0.05% glutaraldehyde for 24 hours. In vitro its degrading rate was measured by use of collagenase degrading test. The chitosan-collagen membrane was implanted to subcutaneous dorsal sites of SD rats. After implantation, histocompatibility, vascularity and degradation were observed in vivo.

In the end, the synthesis condition and influential factors of PU-titania (TiO2) process, such as manufacturing sol (including the amount of water, the amount of PU/Titanium butyrate, the concentration of the solution, the pH value, the kind of alcohol), aging process, theoretical analysis of the dipping process, dry and heat treatment of the gelation, were also discussed especially. FT-IR、SEM、TEM、DLS techniques were applied to analyze and study the reaction mechanism and watch the surface and section of the PU-TiO2 membrane. According to above, it was inferred that PU-TiO2 membrane (containing K600) was better composite.
