Nylon/saponite nanocomposites were synthesized and characterized. The nanocomposites were prepared by means of a fast, efficient, low cost, and environmentally friendly method. All of the tested preparations resulted in the pre-designed nanocomposites. To this end, delaminated saponites were directly synthesized to be used as a filler in a polymer matrix formed by nylon-6 by the in situ intercalation polymerisation of an ε-caprolactam monomer without the use of surfactants or other organic reagents to organophilise the clay, thus avoiding the drawbacks of contamination. The efficiency of the preparation method increased, and significant savings were achieved in terms of both energy reaction time, savings of 60% and 70%, respectively, by using microwave radiation as an energy source during the synthesis of the nanocomposites. In addition, given that the method that was followed avoids the use of contaminating organophilic agents, it is important to highlight the savings in reagents and the fact that there was zero environmental contamination.
合成并表征了尼龙/皂石纳米复合材料。这些纳米复合材料采用快速、高效、低成本且环保的方法制备。所有测试制剂均得到了预先设计的纳米复合材料。为此，通过ε-己内酰胺单体的原位插层聚合，直接合成了剥离皂石，用作由尼龙-6形成的聚合物基体中的填料，无需使用表面活性剂或其他有机试剂对粘土进行亲有机化处理，从而避免了污染问题。制备方法的效率提高了，通过在纳米复合材料合成过程中使用微波辐射作为能源，在能量反应时间方面分别节省了60%和70%，实现了显著的节约。此外，鉴于所采用的方法避免了使用污染性亲有机试剂，突出了试剂的节省以及零环境污染这一事实。
