【摘要】 利用粘度法和电导法研究了顺式氯氰菊酯微乳液微观结构的变化,对其形成机理进行了探讨,并用偏光显微镜和透射电镜等手段进行了表征。研究发现顺式氯氰菊酯微乳液体系随水相含量的增加分别形成了W/O型微乳液、层状液晶、双连续结构和O/W型微乳液;表面活性剂和醇分子之间依靠氢键和范德华力形成各向异性的类线形大分子,被破坏和重排是层状液晶结构区显示出异常流变特性和不规则电导率变化的主要原因。更多还原

【Abstract】 The paper studied the change of microstructures of Alpha-Cypermethrin microemulsion by means of the viscosity,conductivity,and discussed the formation mechanism of Alpha-Cypermethrin microemulsion determined by polarizing microscope and TEM.The study shows that the Alpha-Cypermethrin microemulsion aggregating forms changed form W/O microemulsion,lamella liquid crystal,B.C.structure to O/W microemulsion.With the increase of water the main reason of the abnormal theological property and the irregular conductivity of the lamella liquid crystal region is the destruction and recomposition of the anisotropic similar line big molecule of which the formation depends on the hydrogen bond and the Van der Waals force between the surfactants and the n-hexyl alcohol.更多还原
