Apatite formation on organic polymers by biomimetic process using Na2O-SiO2 glasses as nucleating agent

Journal Article:

Abstract

In this investigation, CaO-SiO2-based glass, which was previously used as the nucleating agent, was replaced by Na2O-SiO2 glasses, SiO2 glass, and SiO2 gel. The induction period for the apatite nucleation on various organic polymer substrates and the adhesive strength of the apatite layer to the substrates were examined. It was considered that the short induction period for the glasses with high Na2O contents was attributed to high dissolution rates of sodium and silicate ions from them. It was also considered that highly polar carboxyl or sulfinyl groups were formed on the polymer surfaces by the hydrolysis of their ester, amide or sulfonyl group in simulated body fluid with its pH increased by the Na{sup +} dissolution from the glass, and that these polar groups formed a strong bond with the apatite. It is suggested that thus formed apatite-organic polymer composites are useful as the bone-repairing as well as soft tissue-repairing materials. 11 refs., 13 figs., 3 tabs.
