COMPOSITE MATERIAL COATED WITH CALCIUM PHOSPHATE-BASED COMPOUND AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a composite material useful as a biocompatible material, filter material or the like by the use of a polyamide as the base through a calcium phosphate-based compound laminating method hard to be affected by the base. SOLUTION: This composite material is obtained by soaking a calcium- containing compound-containing polyamide base in an aqueous solution containing phosphate ion and/or derivative thereof, or by soaking the base in an aqueous solution containing phosphate ion and/or derivative thereof and calcium ion, to form a calcium phosphate-based compound layer on the base.
