【摘要】 钙离子(Ca²⁺)通过阳离子掺杂进入到掺杂了肝素钠的聚吡咯膜中,考察Ca²⁺对聚吡咯膜在模拟体液（SBF）中诱导磷灰石沉积能力的影响。结果表明:Ca²⁺掺入聚吡咯膜后能促进磷灰石在其表面的沉积,缩短涂层沉积的时间,提高了聚吡咯/磷灰石复合材料的制备效率。更多还原

【Abstract】 Ca²⁺ have been incorporated onto polypyrrole（PPy）,which was doped with heparin sodium salt,by cation doping.The effects of the incorporated of Ca²⁺ ions on the ability of bone-like apatite formation in simulated body fluid（SBF） was evaluated.The results suggested that the incorporation of Ca²⁺ onto doped PPy membrane might be an effective and fast way to prepare biomimetic apatite coating on the surface of PPy.更多还原
