摘　　要：采用自由基乳液聚合方法合成了纳米石墨/聚丙烯酸甲酯复合乳液,并用紫外及可见分光光度计和扫描电子显微镜对乳液进行了表征。结果表明:运用丙烯酸甲酯对纳米石墨进行聚合包覆的改性方法实现了纳米石墨在水基液中的稳定分散,并确定最佳聚合条件为:5 h,70℃。Nanographite/poly（methyl acrylate）compound latex was synthesized through in-situ free radical polymerization of methyl acrylamide in presence of the nanographite.The effect of synthetic product was investigated by ultraviolet-visible absorption spectroscopy and scanning electron microscope（SEM）.The results showed that the way of polymeric coat by methyl acrylate realizd the steady decentralization of nanographite in a water-based fluid.The optional polymeric conditions were 70℃,5h.
