23 Jul Cartilage tissue engineering scaffold material
Abstract
The invention discloses a cartilage tissue engineering scaffold material. The cartilage tissue engineering scaffold material is characterized in that: it is compounded by an L-lactic acid polymer and calcium polyphosphate fiber, the molecular weight of the L-lactic acid polymer is 100-150 thousands, the length of the calcium polyphosphate fiber is 8-15mm, and the L-lactic acid polymer and the calcium polyphosphate fiber are in a weight ratio of 1:2-2:1. The cartilage tissue engineering scaffold material provided in the invention has porosity greater than equal to 92%, and compared with the prior art, it has better biodegradability and physical mechanical properties, as well as has a three-dimensionally connected, microporous, and mesh microstructure.
