Biocomposites, also known as biomedical composites, are biomedical materials composed of two or more than two different materials. The purpose of preparing such materials is to further improve or improve the performance of a biological material. These materials are mainly used to repair and replace human tissues, organs or enhance their functions.
According to different substrates, biological composites can be divided into three types: polymer matrix, metal matrix and ceramic matrix. They can be used as the base material, as well as as the reinforcement or filler of biological composite materials, and a large number of biomedical composite materials with different properties are formed by their mutual collocation or combination.
According to the type and degree of tissue reaction caused by material implantation, biocomposites can be divided into bioinert, bioactive, biodegradable and absorbable composites.
The development of biomedical composites has opened up a wide way to obtain biomaterials that are truly biomimetic.
