低温光聚合制备可降解多孔支架及其性能
Preparation and Properties of Biodegradable Crosslinking Porous Scaffolds Materials via Low Temperature Phase Separation Photopolymerization
摘要
Abstract
The double bond-terminated polycaprolactone dimethacrylate (PCLDMA)and the double-capped polylactic acid dipropyl methacrylate (PLADMA)were synthesized.The biodegradable porous scaffolds were prepared by low temperature photopolymerization induced phase separation.The results of scanning electron microscopy showed the higher the solvent content,the higher the porosity and the larger the pore size.The size of the pores decreases gradually as the cooling temperature decreases,the faster the cooling rate,the smaller the porosity and pore size.The thermal stability of PCLDMA por-ous scaffold was higher than that of PLADMA.Two kinds of materials in PBS solution were stable and slow degradation in vitro.The mechanical properties of PLADMA porous scaffold have high com-pressive strength and elastic modulus,and the brittleness of PCLDMA scaffold has low compressive strength and elastic modulus,but possessed good toughness and some deformation recovery.关键词
