摘要
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 +/- 81 mu m 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 (C) 2010 Elsevier Ltd All rights reserved
