Study on Hydroxylapatite Fibroin Porous Composite
The complex porous materials, Hydroxyapatite(HA)/silk fibroin, were prepared using ultrasonic vibration gel method in this paper. The mechanical properties decreased with the increase of HA while the porosity increased. The pore size become bigger than 100μm when adding silk fiber in the complex materials, and the breaking energy increased evidently from 10 to 1000 J/m2 when fiber content increased from 0 to 4 wt.%. It was observed from SEM that all composites have interconnected micropores.
