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.
