PA6/蒙脱土熔融插层复合材料结构与性能分析

通过熔融共混法插层复合制备了聚酰胺(PN)6／蒙脱土纳米复合材料，测试了力学性能并对不同蒙脱土含量的PA 6／蒙脱土纳米复合材料进行了对比。实验表明，通过熔融插层可使PN 6基体插层于蒙脱土中，所得到的复合材料的性能较PN 6有很大提高。蒙脱土特殊的层状结构使得利用熔融共混在机械力的作用下插层到纳米级复合材料成为可能。

Study on structure and properties of melt-intercalated polyamide 6/montmorillonite nanocomposites

The polyamide (PA) 6/montmorillonite nanocomposites were successfully prepared through melt intercalation process. The mechanical property of the melt-intercalated composites were compared with that of the intercalated composites of PA 6/montmorillonite prepared via polymerization process. The results show that PA 6 is intercalated into montmorillonite through the melt intercalation process and the nanocomposites so obtained possess a mechanical performance superior to pure PA 6. The lamellar structure of montmorillonite makes it possible to intercalate PA 6 into the nanocomposites under the action of mechanical force during the melt blending process.
