使用三烷基咪唑鎓四氟硼酸盐相容的多壁碳纳米管（MWNT）/聚苯乙烯纳米复合材料，通过熔融挤出制备了分散良好的多壁碳纳米管（MWNT）/聚苯乙烯纳米复合材料。通过透射电子显微镜和激光扫描共焦显微镜图像分析实现的改进的量化。差示扫描量热法和傅里叶变换红外和X射线衍射分析显示了π阳离子、纳米管-咪唑相互作用的证据，以及咪唑盐从叉指双层转变为MWNT表面咪唑的有序层状结构的证据。
Well-dispersed multiwalled carbon nanotube (MWNT)/polystyrene nanocomposites have been prepared via melt extrusion, using trialkylimidazolium tetrafluoroborate-compatibilized MWNTs. Quantification of the improvements realized via transmission electron microscopy and laser scanning confocal microscopy image analysis. Differential scanning calorimetry and Fourier-transform infrared and X-ray diffraction analysis show evidence for a pi-cation, nanotube-imidazolium interaction and the conversion from an interdigitated bilayer, for the imidazolium salt to an ordered lamellar structure, for the imidazolium on the surface of the MWNTs.
