Abstract: This paper discussed the preparation methods and material properties of silk fibroin fiber porous materials,regenerative silk fibroin sponge porous materials and silk fibroin non-woven nanofiber porous materials.It is believed that these materials have appropriate porous structure and excellent biocompatibility,a variety of cells from different apparatus or tissue cultured on these materials and showed attachment and proliferation.Application states of silk fibroin porous materials used in tissue engineering of artificial skin,bone,cartilage,artificial ligament and muscle tendon were summarized as a kind of nice tissue engineering scaffold material.
