PREPARATION METHOD OF HYDROXYAPATITE-CHITOSAN COMPOSITE COATING LAYER USING AEROSOL DEPOSITION AND HYDROXYAPATITE-CHITOSAN COMPOSITE COATING LAYER WITH ENHANCED BIOACTIVITY

摘要

PURPOSE: A preparation method of a hydroxyapatite-chitosan composite coating layer is provided, which allows good cohesive power by coating a hydroxyapatite-chitosan composite coating layer on a substrate at the room temperature. CONSTITUTION: A preparation method of a hydroxyapatite-chitosan composite coating layer comprises: a step of heat-treating hydroxyapatite material powder; a step of manufacturing composite powder by dry milling heat-treated hydroxyapatite powder and chitosan powder; and a step of coating hydroxyapatite-chitosan composite powder on a substrate by an aerosol deposition method.
