摘　　要：设计、合成了含有苯胺二聚体的苯乙烯甲基丁酸酯(VPB),通过自组装-自由基聚合的方法,成功地制备了聚合物纳米片层材料.VPB和聚合物的结构通过核磁谱和红外光谱进行了分析确认,VPB和聚合物的自组装行为通过电子显微镜、X射线进行了研究.实验结果表明,VPB在甲苯和丙酮的混合溶剂中可以自组装成为二维纳米片层,并能与马来酰亚胺进行自由基共聚反应,形成尺寸数微米、厚度2纳米的聚合物片层材料.本研究的结果证明,将自组装与自由基聚合结合是一种制备聚合物二维纳米片层材料的有效方法.4-vinyl benzyl 4-oxo-4-（（4-（phenylamino）phenyl）amino）butanoate （VPB） were designed and synthesized, and then polymer nanosheets were successfully prepared by self-assembly and polymerization of the VPB. Structures of the VPB and the polymer were characterized by 1HNMR spectroscopy and infrared spectroscopy. Self-assembly of the VPB and the polymers were investigated by transmission electron micrography and X-ray analysis. The results indicate that VPB can self-assemble into twodimensional nanosheets in the mixed solution of toluene and acetone, and morever, VPB can be copolymerized with N-butyl maleimide to form a polymer nanosheet with a size of several micrometers and thickness of 2 nanometers. It has been demonstrated that the combination of self-assembly and free radical polymerization is a convenient and efficient approach for the preparation of polymer nanosheets.
