发现蒙脱石插层有ε-己内酰胺。 X射线衍射表明ε-己内酰胺的链轴平行于蒙脱石板。插层蒙脱石在 200 摄氏度下被熔融的ε-己内酰胺溶胀。 ε-己内酰胺和6-氨基己酸（促进剂）与插层蒙脱土在260℃下聚合6小时，产生尼龙6-粘土杂化物。 X 射线衍射和透射电子显微照片显示，杂化材料的硅酸盐层均匀分散在尼龙 6 基体中。混合体的机械性能得到改善。与之前报道的由蒙脱石插层12-氨基月桂酸合成的尼龙6粘土杂化物(NCH)相比，该杂化物的强度和模量有所增加。该杂化材料的热变形温度（HDT）为164℃，比NCH高12℃。
It was found that montmorillonite was intercalated with epsilon-caprolactam. X-ray diffraction revealed that the chain axes of the epsilon-caprolactam were parallel to the montmorillonite plates. The intercalated montmorillonite was swollen by molten epsilon-caprolactam at 200-degrees-C. Epsilon-caprolactam and 6-aminocaproic acid (accelerator) were polymerized with the intercalated montmorillonite at 260-degrees-C for 6 h, yielding a nylon 6-clay hybrid. X-ray diffraction and transmission electron micrography revealed that the silicate layers of the hybrid were uniformly dispersed in the nylon 6 matrix. Mechanical properties of the hybrid were improved. The strength and the modulus of the hybrid increased compared with the previously reported nylon 6 clay-hybrid (NCH) synthesized by montmorillonite intercalated with 12-amino-lauric acid. The heat distortion temperature (HDT) of the hybrid was 164-degrees-C, which was 12-degrees-C higher than that of NCH.
