Abstract

Polycaprolactone (PCL)/hydroxyapatite whisker (HAw) composite porous scaffolds were prepared by solution casting method with dichloromethane as solvent.The orthogonal test was conducted to compare composites with the different formulas of PCL and HAw.The results shown that the mechanical properties of the scaffolds were controlled by the amount of PCL.The hydrophilicity of the scaffolds could be improved by adding HAw.The composites shown that the contact angle was 81°,which was hydrophilic.The crystallinity of PCL increased with the increasing of HAw.The tensile strength of the scaffolds was 1.43~9.21MPa,and reached to the maximum when the mass ratio of PCL to HAw was 100∶3.The cytotoxicity experiment showed that the cytotoxicity of the scaffolds was 0,which could meet the requirements for the use of biological materials.
