摘要：
The invention involves a kind of electrified composite membrane with extracellular matrix electrical topology characteristics and its preparation method, which resolves the technical problems of poor matching of electric characteristics and natural extracellular matrix characteristics in the existing materials and limited restoration effect of materials. The invention provides a kind of electrified composite membrane with extracellular matrix electrical topology characteristics mainly composed of ferroelectric polymer matrix and piezoelectric active fiber fillings. By regulating the draw ratio, content and of piezoelectric active fiber and thickness of composite film, the invention can realized the flexibility of film material and electrical topological features of bionic extracellular matrix, with proper tissue adhesion and good electric adaptability and high clinical operability.
