Abstract

The surface of ethylene-vinyl alcohol copolymer (EVOH) was modified with Ti-OH groups by treatments with a silane coupling agent and a titania solution. Arrangement of the Ti-OH groups on the specimen was changed into anatase by a treatment with ultra-pure water or a HCl aqueous solution. Thus surface-modified specimen formed apatite on its surface in a simulated body fluid (SBF) with ion concentrations nearly equal to those of human blood plasma within 2 d. The present surface-modification of EVOH would be useful for producing a bone substitute with bone-bonding ability as well as analogous mechanical properties to those of natural bone.
