在不对粘土矿物和添加剂进行任何处理的情况下，采用固相剪切球磨法成功制备了聚酰胺6/天然粘土矿物纳米复合材料。采用盘磨机设备对PA 6/粘土混合物进行盘磨机，制备PA 6/粘土复合粉末。将所得粉末作为母料用纯PA 6稀释以通过双螺杆挤出机制备复合材料。粘土硅酸盐层被发现是部分剥离和均匀分散在尼龙6基体中的纳米水平。对纳米复合材料的流变性能和力学性能进行了表征。随着粘土含量的增加，纳米复合材料的剪切粘度比纯PA 6的剪切粘度高，拉伸强度和拉伸模量增加，冲击强度降低。© 2005 Wiley Periodicals，Inc.聚合物科学杂志B部分：聚合物物理44：249-255，2006
The polyamide-6 (PA6)/natural clay mineral nanocomposites were successfully prepared by solid-state shear milling method without any treatment of clay mineral and additives. PA6/clay mixture was pan-milled to produce PA6/clay compounding powder, using pan-mill equipment. The obtained powder as master batch was diluted with neat PA6 to prepare composites by a twin-screw extruder. The clay silicate layers were found to be partially exfoliated and dispersed homogeneously at nanometer level in PA6 matrix. The rheological measurements and mechanical properties of nanocomposites were characterized. The shear viscosities of nanocomposites were higher than that of pure PA6, and tensile strength and tensile modulus increased, but Izod impact strength decreased, with increasing concentration of clay. © 2005 Wiley Periodicals, Inc.
