采用聚甲基丙烯酰氧基乙基磷酸酯（pMOEP）通过接枝共聚对真丝织物进行改性。与原始丝织物相比，pMOEP 接枝丝织物上的 Ca 吸附显着增强。 SEM观察表明，接枝pMOEP的丝织物在模拟体液中浸泡1周后，出现了一些微晶沉积，而原丝织物表面没有发生任何变化。 X射线衍射表明该微晶含有羟基磷灰石。这些结果表明，pMOEP 接枝丝织物比原始丝织物更有效地诱导羟基磷灰石形成。
Silk fabric was modified with polymethacryloyloxyethylphosphate (pMOEP) by graft copolymerization. Ca-adsorption onto pMOEP-grafted silk fabric was significantly enhanced compared to that onto original silk fabric. SEM observation indicated that some crystallites were deposited on the pMOEP-grafted silk fabric after 1 week of immersion in simulated body fluid, whereas no change occurred on the surface of the original silk fabric. X-ray diffraction showed that this crystallite contained hydroxyapatite. These results indicate that pMOEP-grafted silk fabric induce hydroxyapatite formation more effectively than the original silk fabric.
