Biodegradable photopolymerizable polymer composite material by layered manufacturing and its application

Abstract

The invention relates to a biodegradable photopolymerizable polymer composite material by layered manufacturing and its application. The biodegradable photopolymerizable polymer composite material hasexcellent biocompatibility and bioabsorbability, has the advantages of adjusting physical properties and degradation degree, degradation forms or rate through different formulation ratios of the materials, is an excellent biomedical material and tissue engineering material, which comprises PGSA, a photoinitiator having biological compatibility and a group selected from PCL-DA, and PEG-DA. The material adopts the different ratios of the materials such as PGSA, PCL-DA and PEG-DA, and can adaptively produce the materials having different soft elasticity, mechanical properties, degradation formsand extensibility, and is suitable for manufacturing different tissues in organism, organs or the related products.

Description

technical field [0001] The invention relates to a biodegradable photopolymerizable polymer composite material, in particular to a biodegradable photopolymerizable polymer composite material suitable for lamination manufacturing. Background technique [0002] Biomedical materials are materials applied to medical equipment or tissue engineering, which can interact with organs, tissues and systems in living organisms, and can be used to repair or even directly replace biological living systems, and can perform the functions of the systems smoothly. The function of materials mainly includes replacing damaged and functionally missing parts of organisms, assisting wound healing and repairing, enhancing the function of organs and tissues, or directly replacing defective and abnormal tissues and organs, etc. Since biomedical materials may be directly applied to living organisms, in addition to the general physical and chemical properties, it is necessary to further consider their bi...
