INVESTIGATION OF EFFECTIVE PROCEDURES IN FABRICATION OF BIOACTIVE PEEK USING THE FUNCTION OF APATITE NUCLEI

Abstract

: We made micropores on the surface of a polyether ether ketone (PEEK) by immersing in sulfuric acid. In order to provide bioactivity to PEEK, we treated the surfaces of the specimens with glow-discharge in O 2 gas atmosphere and precipitated Apatite Nucleus (AN) in the micropores. We evaluated apatite-forming ability of the specimens by using SBF and measured adhesive strength of formed apatite layer. In this study, we researched which treatment is effective to give bioactivity to PEEK.
