以高分子模板为材料，采用滑移浇铸法制备了多孔羟基磷灰石（HA）支架。模板采用聚合物珠、NaCl和粘合剂（N100）制备。研究了制备工艺对多孔透明质酸支架的孔隙结构和力学性能的影响。通过在聚合物模板中加入合适粒径的NaCl颗粒，提高了孔隙的连通性。通过调节N100的浓度可以控制粘接面积的大小。通过改变聚合物微球的尺寸和NaCl颗粒的体积，可以将孔隙尺寸控制在200±42 ~ 400±81μm之间，孔隙率控制在50.2 ~ 73.1%之间。抗压强度随孔隙率或孔径的增大而减小。
Porous hydroxyapatite (HA) scaffolds with interconnected spherical pores were fabricated by slip casting using a polymer template. Templates were produced using polymer beads, NaCl, and adhesive (N100). Effects of the preparation process on the pore structures and mechanical properties of the porous HA scaffolds were investigated. Pore interconnectivity was improved by adding NaCl particles with appropriate diameters to the polymer template. The size of the adhesive area could be controlled by adjusting the concentration of N100. The pore size could be controlled between 200±42 and 400±81μm, and the porosity between 50.2 and 73.1%, by changing the size of the polymer beads and the volume of the NaCl particles. The compressive strength decreased as the porosity or pore size increased.
