Abstract

In the presence of fine silk cocoon (silk fibroin, SF) powder, a low viscosity sol of nano-hydroxyapatite (HAp, Ca10(PO4)6(OH)2)-SF was synthesized by a wet mechanochemical reaction. Nano crystals of HAp are oriented along their c-axis. The secondary structure of SF was changed by milling. A uniform thin gel film was obtained by a simple dip coating on the glass substrate precoated by chitosan.
