23 Jul Composite superfine fibre membrane of biologic compatible shell core structure and preparation method thereof
Abstract
The invention provides a composite superfine fibre membrane material of a biologic compatible shell core structure and a preparation method thereof. The composite superfine fibre of the biologic compatible shell core structure, which comprises 20-95% of shell layer biomacromolecule by mass percent and 5-80% of core layer colloid by mass percent, is mainly prepared by utilizing an electrostatic spinning method with simple and easy operation. The composite superfine fibre membrane material of the biologic compatible shell core structure has light and flexible quality, good air permeability and favorable biologic compatibility, biologic degradability and biologic absorptivity, can be used as an active medicine carrier material, can completely package various active medicines, realize the independent controlled release of various medicines and has extensive application prospect in the aspects of tissue engineering bracket materials, wound coating materials, artificial dressings, multi-functional composite membranes and the like.
