【摘要】 <正> 近年来,基于有机高分子和片层结构的无机粘土的纳米复合在有机-无机复合材料领域中非常引人注目。就目前的研究状况而言,通常认为粘土有机化处理是生成纳米复合材料(插层/剥离型)的必要条件。而从实际的生产过程和材料的加工工艺的角度考虑,如果能够采用天然粘土直接与聚合物进行熔融复合制备纳米复合材料,可以大幅度地降低生产成本,同时减少能源消耗和环境污染。这方面的文献报道相对较少。其中,有采用反应性相容剂对EVA/未处更多还原

【Abstract】 Nylon 6/natural montmorillonite nanocomposites were prepared via direct melt extrusion. The results indicate that with appropriate selection of intercalation agents as well as favorable control of processing condition, nanocomposites with well dispersed state and high properties could be obtained using unmodified clay. It is of interest to note that the employment of macromolecular co-intercalation agent with functional groups have notable influence on the composite system investigated.更多还原
