Abstract

Sulfonic groups (-SO₃H) were covalently attached on different polymeric surfaces enabling them to induce apatite nucleation, for developing bioactive apatite-polymer composites with a bonelike 3-dimensional structure. High molecular weight polyethylene (HMWPE) and ethylene-co-vinyl alcohol co-polymer (EVOH) were used. The polymers were soaked in two types of sulphate-containing solutions with different concentrations, sulphuric acid (H₂SO₄) and chlorosulfonic acid (ClSO₃H). To incorporate calcium ions into to the sulfonated polymers, the samples were soaked in a saturated Ca(OH)₂ solution for 24 hours. After soaking of the samples in a simulated body fluid (SBF), formation of an apatite layer on both surfaces was observed. The results obtained prove the validity of the proposed concept and show that the -SO₃H groups are effective on inducing apatite nucleation on the surface of these polymers.
