用MMA作为油相，制备了纳米AgCl/MMA反相微乳液，聚合MMA合成了AgCl/PMMA 复合纳米材料。电导测试表明，温度与R（水/表面活性剂的摩尔比）影响着反相微乳液的形成，如Fig 1中R1¢-R2¢、R1-R2为保持NaCl、AgNO3的反相微乳液球形结构的最佳范围。

对复合材料进行了力学分析，杨氏模量及冲击强度都得了增强，粒径越小（即图中浓度越小）增强的效果越好，如Fig3、Fig4。认为纳米粒子与聚合物之间界面粘接越强，纳米粒子与聚合物之间形成的中间相层就越易诱发银纹的产生，复合材料的强度和韧性越好。并用Einstein模型处理AgCl/PMMA复合材料界面间的作用强弱，发现聚合物与纳米AgCl之间粘接良好，粘接系数B达到2.35，如Fig 5.

AgCl/PMMA nano-composites are prepared with reverse template. Electronic conductivity testing shows that the temperature and R( water/surfactant molar ration) affect the structure of reverse microemulsion. TEM and SEM are employed to characterize the nano-composite. Mechanical testing shows that the Young modulus and the toughness reinforced in the nano-composites. It is explained that stronger adhesion between polymer and nano-particles makes the interphase layer induce the crack occurred easily, which make the nano-composite toughen and reinforcement. With calculation the adhesion between polymer and nano-particles with Einstein formula, we find that there is strong adhesion between polymer chains and nano-AgCl.
