摘　　要：采用常压共溶复合工艺,在溶液体系中合成了分散均匀的n-CHA/HDPE,n-CHA/gHDPE两种生物功能材料,利用各种检测手段分析复合材料的界面结合状态。结果表明:n-CHA/HDPE复合材料是简单物理共混;而n-CHA/gHDPE复合材料则具有稳定的界面结合,n-CHA与gHDPE两相界面间有化学键形成。Two functionalized biomaterials were prepared in solution system by a new method at normal atmosphere. They were nano-carbonate hydroxyapatite reinforced high density polyethylene composite （n-CHA/HDPE） and n-CHA reinforced maleic anhydride grafted high density polyethylene composite （n-CHA/gHDPE）. The interface of composites was analyzed in terms of burning test, TEM, IR, XRD and Molau testing. The results showed that n CHA/HDPE composite was simple mechanical mixed, but n-CHA/gHDPE composite had stable interface connection based on the chemical bonding as esterification and hydrogen bonding formed between the two phases.
