摘要: To produce a bone-bonding polymer surface that is capable of inducing deposition hydroxyapatite (HA) layer in the body fluid, an organophosphate was covalently immobilized onto high-density polyethylene film by graft polymerization phosphate-containing monomer. The grafted immersed simulated physiologic solution (SPS). chemical composition and structure formed apatite as well its bonding strength to were investigated. distinguish effect phosphate groups on from simple calcium absorption anion, comparative study done using with carboxylic groups. Calcium observed all materials investigated, but kinetics, composition, deposit amount, new phase found be significantly different among modified materials, depending density nature ionic It polymeric monomer carbonated HA firmly bonded material upon immersion SPS.
