Abstract

The invention discloses an inorganic bioactive material and a method for a polymer porous composite material. The method comprises the following steps of: selecting a pore-forming agent with required particle size; mixing the inorganic bioactive material, polymer, an organic solvent and the pore-forming agent; placing an obtained mixture into a die and carrying out curing; and removing the pore-forming agent to obtain the porous composite material. According to the invention, a die plate and the pore-forming agent can be synthesized and formed in one step by pressurization and polymerization; the process is simple; the uniformity and the continuity of pores are ensured; and a good environment can be provided for subsequent cell growth and tissue neogenesis. Moreover, the prepared material has certain elasticity and has good ductility.

Description

technical field [0001] The invention relates to the preparation of porous composite materials, in particular to a preparation method of inorganic bioactive materials and polymer porous composite materials. Background technique [0002] Hydroxyapatite (HAP) has excellent biocompatibility and is an important component of bones and teeth. Hydroxyapatite is similar to the inorganic components of human bones, non-toxic and harmless, has good biocompatibility and bioactivity, and has the ability to guide bone formation. However, as a bone substitute material, HAP also has its own shortcomings, such as poor mechanical properties, which limit its application. [0003] Bioglass is a glass that can achieve specific biological functions. When it is placed in a physiological solution, it can induce the formation of hydroxyapatite. Therefore, when implanted in the human body, it can repair bone tissue and has the functions of osteoconduction and osteoinduction. [0004] Combining polym...
