TITANIUM OXIDE-ORGANIC POLYMER CONJUNCTION SUITABLE FOR ARTIFICIAL BONE

摘要

A material composed of titanium oxide and an organic polymer obtained by subjecting a base material, which is made of a polymer compound selected from the group consisting of polyolefins, polyesters and nylon, to a titania solution treatment of immersing in a solution obtained by adding a solution comprising an acidic alcohol with water to an alcoholic solution of a titanium tetraalkoxide at 0°C to 50°C for several seconds to 1 week to thereby form a titania gel on the surface of the base material, and then immersing the base material having the tatania gel formed thereon in warm water (50°C to 95°C) or an acid-containing solution (room temperature to 95°C) to thereby convert the titania gel into a titanium oxide film having an activity of forming apatite having the same Ca/P atomic ratio as that of mammalian bone apatite from an apatite-excess aqueous solution or a mammalian body fluid.
