| Research Abstract |
It is difficult to produce practically applicable artificial skins and molded materials. Recently it has been reoprted that the physical properties of the former decreased with the increase of the beta-structure. Therefore, an attempt has been made in order to produce a practically applicable artificial skin having better physical properties by blending of the silk with other natural polymers. A composite membrance of silk and chitosan can be produced which have network structures and better mechanical properties due to the good miscibility of these two polymers. The silk powder produced by the acid decomposition was found to be suitable for producing artificial bones when the silk powder was treated for 10 minutes under a pressure of 1000 kg/cm^2 at 150ﾟC.Sufficient strength and water resistability could ont be achieved with the silk powder alone. Therefore, glycidylmethacrylate (GMA) was blended with silk and practically applicable molded material was successfully produced. It was found that the application of molded silk as a substitute of bones is possible.
