Abstract

A composite tissue-engineered porous scaffold material is prepared from the nano-class hydroxy phosphorite particles, medical polyamide and foaming agent through proportionally mixing, heating to fuse it, injection moulding under 30-50 MPa to form porous scaffold, and removing the surficial layer to open the pores. Its advantage is high mechanical performance.

Description

technical field

[0001] The invention relates to a preparation method of a nano-apatite crystal composite tissue engineering support material, specifically a preparation method of a porous tissue engineering support material in the form of a nano-hydroxyapatite / medical polyamide compound. Background technique

[0002] One of the key technologies of tissue engineering is the research and preparation of scaffold materials.

[0003] Natural bone is an inorganic / organic composite material composed of nano-apatite and polymer collagen fibers, which has good mechanical properties. Based on the concept of bionics, people hope to prepare a bioactive material with good mechanical strength and toughness, and an elastic modulus close to natural bone. As a tissue engineering scaffold material for extracellular matrix, it must have good mechanical strength, and it is difficult for a single material to meet the requirements of bone tissue engineering cell scaffold materials. For example,...
