摘　　要：应用电子自旋共振法对TritonX - 10 0、正戊醇、正己醇、正庚醇、正辛醇及辛烷形成的反相微乳液进行了研究 ,研究结果表明反相微乳液的形成过程伴随着表面活性剂链排列的变化 ,在加入水量较少时栅状区域的表面活性剂链排列拥挤 ,进一步的水化作用使其排列疏松。而疏水性强的探针则表明水化作用渗透到了反相微乳液的疏水区域。The associated structure of TritonX-100 reverse microemusion formed by octane and different co-surfactants such as petanol, hexanol, heptanol and octanol is studied with ESR. It is shown that the formation of reverse microemusion is accompanied by the change of surfactant chains, and it becomes loose with further hydration process . Results labeled by hydrophilic probe show that hydration action permeates into hydrophilic region of reverse microemulsion
