采用聚丙烯酸钠（PAS）对凹凸棒土（AT）进行表面处理，然后通过简单熔融共混法制备了聚酰胺6（PA 6）/AT纳米复合材料。透射电镜（TEM）和傅里叶变换红外光谱（FT-IR）分析表明，PAS对AT进行了提纯和表面改性。X射线衍射分析表明，AT在PA 6基体中的微观结构几乎没有变化。通过对纳米复合材料的断口分析、玻璃化转变温度（T.）获得的动态力学分析，和界面相互作用的因素;场发射扫描电子显微镜的纳米复合材料的断裂表面上显示，AT的均匀分散得到。上述两个方面符合纳米复合材料的力学性能和热性能的改善。Polym.比较器：30：147153，2009. (C)2008年塑料工程师学会
Attapulgite (AT) clay was firstly treated with sodium polyacrylate (PAS), then polyamide 6 (PA6)/AT nano-composites were prepared by simple melt compounding. Transmission electron microscope (TEM) and Fourier transform infrared spectrometry (FT-IR) of treated AT confirm the success of purifying and surface modification of the original AT by PAS. X-ray diffraction spectra for the nanocomposites show that the microstructure of AT in PA6 matrix is almost unchanged. It indicates that a strong interfacial adhesion exists between AT and PA6 matrix through analyzing fracture surfaces of the nanocomposites, the variation of glass transition temperature (T.) obtained by dynamic mechanical analysis, and interfacial interaction factors; field emission scanning electron microscopy on the fracture surfaces of the nanocomposites shows that a uniform dispersion of AT is obtained. The above two aspects conform to the improvement of mechanical and thermal properties of the nanocomposites. POLYM. COMPOS., 30:147153, 2009. (C) 2008 Society of Plastics Engineers
