A polymer -hydroxyapatite (HAp) composite is useful as hard tissue engineering scaffold materials for bone and teeth, particularly. It is necessary to control the form of the composites precisely, because form of bone and teeth is unique and specific. We demonstrated that the shape of a base polymer

## Abstract A novel bone graft substitute comprising a porous, collagenous scaffold was biomimetically coated with hydroxyapatite using a simulated body fluid solution chemistry method. The scaffold had a porosity of approximately 85%, with pore sizes between 30 μm and 100 μm. Glutaraldehyde vapor
Synthesised hydroxyapatite (HAp)/a-tricalcium phosphate (a-TCP) composites were prepared by colloidal process. Mixed slurries composed of 30 vol% HAp/a-TCP powder and 70 vol% aqueous solution containing a small amount of polymer dispersant were produced. HAp/a-TCP powder was blended with 0, 0.2, 0.4
