CHARGED COMPOSITE MEMBRANE HAVING ELECTRICAL TOPOLOGY CHARACTERISTICS OF EXTRACELLULAR MATRIX AND PREPARATION METHOD THEREFOR

摘要

Disclosed is a charged composite membrane having electrical topology characteristics of an extracellular matrix and a preparation method therefor. The charged composite membrane having electrical topology characteristics of an extracellular matrix is mainly composed of a ferroelectric polymer matrix and a piezoelectric active fiber filler. The length to diameter ratio of the piezoelectric active fiber, the content of the piezoelectric active fiber, and the thickness of the composite film are adjusted to achieve the flexibility of the membrane material and the electrical topology characteristics of the biomimetic extracellular matrix. The membrane demonstrates excellent tissue adhesion and electrical compatibility, and has strong clinical application.
