Study on the optical properties of transparent epoxy / clay nanocomposites a new type transparent epoxy based nanocomposites has been prepared by the reaction of alkylammonium exchanged montmorillonite ( amt ) with diglycidyl ether of bisphenol a ( dgeba ) and triethylamine as the curing agent . the morphology of amt in the epoxy matrix was characterized with x - ray diffraction ( xrd ) , scanning electron microscopy ( sem ) and transmission electron microscopy ( tem ) 光学透明环氧树脂粘土纳米复合材料光学性能采用十八烷基伯胺盐、十六烷基三甲基溴化胺处理na基蒙脱土制备出两种不同的有机土,以三乙胺为固化剂,有机土与双酚a型环氧树脂熔融插层聚合后制备出剥离型和插层型两种结构的环氧树脂粘土纳米复合材料。
