Abstract To obtain three dimensional mesh nano-hydroxyapatite/graphene oxide composites, a surface modified hydroxyapatite (SHA) obtained by grafting with citric acid. The SHA particles were covered by GO in SHA/GO composites, and the structure of composites is three-dimensional structures. The biomimetic mineralization in SBF solution showed the bone-like apatite layer on composites surface. Aspirin was loaded onto the SHA/GO composites. The change of GO content in composites has a great influence on the adsorption performance of Aspirin.

合成嵌入三维氧化石墨烯网络的表面改性羟基磷灰石用于载药

摘要 为了获得三维网状纳米羟基磷灰石/氧化石墨烯复合材料，采用柠檬酸接枝获得的表面改性羟基磷灰石（SHA）。SHA/GO复合材料中的SHA颗粒被GO覆盖，复合材料的结构为三维结构。SBF溶液中的仿生矿化显示复合材料表面有类骨磷灰石层。阿司匹林被加载到 SHA/GO 复合材料上。复合材料中GO含量的变化对阿司匹林的吸附性能有很大影响。
