23 Jul Porous frame material of poly-lactic acid-polyether block copolymer and its preparation method
Abstract
A polylactic acid-polyester block copolymer used for cell-affinity 3D porous scaffold material in tissue engineering is prepared by copolymerization of D,L-lactide (D,L-LA) with polyether. The said 3D porous scaffold material is prepared from said block copolymer through preparing porous film by solvent casting and particle filter, and shaping by use of chloroform to adhere the porous film for particular shape. Its advantages are a certain hydrophilicity, high biocompatibility, and high porosity (90% or more).
