Amino-bearing polymers, coated with apatite or similar minerals, have attracted significant attention for their potential in medical applications. In this study, an amino-terminated hyperbranched polybenzimidazole (HBPBI) membrane was used as a substrate for apatite growth. The membrane was soaked in solutions of CaCl2, Na2HPO4 and SBF to yield an apatite coating. The structure and morphology of the layers were characterized by FTIR-ATR, XRD and FESEM. The results indicate that the high densities of amino, imide and imidazole groups on the amino-terminated HBPBI membrane provide active sites for the growth of apatite.
含氨基的聚合物，涂有磷灰石或类似的矿物质，因其在医学应用中的潜力而受到广泛关注。在这项研究中，一种末端为氨基的超支化聚苯并咪唑（HBPBI）膜被用作磷灰石生长的基底。将膜浸泡在 CaCl2、Na2HPO4 和 SBF 溶液中，得到磷灰石涂层。通过 FTIR-ATR、XRD 和 FESEM 对各层的结构和形貌进行了表征。结果表明，氨基末端 HBPBI 膜上高浓度的氨基、酰亚胺和咪唑基团为磷灰石的生长提供了活性位点。
