为了研究尼龙 6 /粘土纳米复合材料制备和结构 ,采用合适的改性剂对粘土进行有机改性 ,改性后的有机土与尼龙按一定比例在具有反螺纹段的双螺杆挤出机中熔融复合。TEM测试结果表明 :大多数粘土以单晶层均匀分散于基体中 (即使有少数以多晶层出现 ,厚度大约 2 0nm) ,形成纳米复合材料 In order to study the preparation and structure of nylon 6 / clay nanocomposites, the clay was modified by a suitable modifier. The modified organic soil and nylon were melted in a certain proportion in a twin-screw extruder with a reverse-threaded section complex. TEM test results show that most of the clay uniformly dispersed in the matrix as a single crystal layer (even with a few polycrystalline layer, the thickness of about 20nm), the formation of nanocomposites
