Fabrication of Porous Hydroxyapatite (HAp) Using Polyacrylonitrile (PAN) and Its Characterization

Abstract

Porous hydroxyapatite (HAp) bodies were prepared by the simple process. Porous fibers consisting of polyacrylonitrile (PAN) and HAp were fabricated by extrusion of mixtures of PAN and HAp in dimethylformamide (DMF) solution. Fibers obtained by this extrusion method were chopped and molded. Subsequently, these compactions from chopped fibers consisting of HAp and PAN were sintered at various temperatures in air. The sintered HAp bodies had high porosity and a number of pores with those diameter some hundreds μm. These porous HAp bodies can be used as a scaffold in the body.
