Using silk as material,silk protein was obtained by way of heating and hydrolysis under alkaline condition.

And the article discussed the development of silk protein in the interior and exterior of the country.

Objective Toinvestigate cytotoxity of silk protein materials and their effect on prolif-eration of rat embryoepithelial cells.

This paper summarized the composing and capability of silk fibroin in the past several decades and presented its new utilization and using principle, the method of silk fibroin to degum and refine, and the application and progress in study on silk fibroin in cosmetic, curative, carrier material for immobilized enzyme,food,regenerated filament, paint film on chemical fiber surface and so on.

The silk fibroin and the viscose are blended,and the rotatory viscosimeter is used to test the rheologic property of the silk fibroin/viscose blend solution.

Copolymer of fibroin and acrylonitrile was produced through copolymerization of fibroin and acrylonitrile in sodium sulfocyanate solution.

The results showed that:the silk protein glue was heated with magnetic stirring and adding water,mixing speed was 180r/min,silk protein edible glue liquid packaging films was made by adding 0.

With the sol-gel method,the regenerated SF(silk fibroin)/nano-TiO2 composite films were synthesized using the different ratios of SF and TiO2.

Polyaniline/silk fibroin composite film was fabricated successfully by in-situ chemical oxidation polymerization.
