23 Jul Biodegradable polymer composite material and preparation method thereof
Abstract
The invention provides a biodegradable polymer composite material which is a novel composite material consisting of fully biodegradable polymer and nanometer/micron particles of which the surfaces are grafted with amidogens, wherein the percentage by weight of the nanometer/micron particles in the composite material is 0.1%-10%, and the particle size of the nanometer/micron particle is 5 nm-1 mum. The biodegradable polymer composite material disclosed by the invention has uniform properties and good mechanical performance, can be widely used in various fields of medical equipment of orthopedics materials, tissue engineering stent materials, interventional medical device (such as endovascular stents) materials and the likes.
