通过丙烯酸钠和季铵氯化物基团之间的亲和络合物的静电相互作用，将纳米级聚（乙二醇二甲基丙烯酸酯-co-丙烯酸钠）（poly（EGDMA-co-AcNa））粒子有效地自组装到聚（二乙烯基苯-co-苯乙烯基甲基三甲基氯化铵）（poly（DVB-co-StMTMACl））表面，得到具有树莓状结构的核-冠复合粒子.通过扫描电镜（SEM）和透射电镜（TEM）研究了盐电解质对树莓状聚合物复合材料形貌的影响。聚（DVB-共-StMTMACl）核、聚（EGDMA-共-AcNa）冠和树莓样复合物的ζ-电位（xi）值通过ζ-电位分析仪测定。利用接触角测量系统研究了水在由树莓状颗粒形成的微纳二元粗糙聚碳酸酯（PC）薄膜表面的静态接触角。(c)2008 Elsevier B.

Nano-sized poly(ethyleneglycol dimethacrylate-co-sodium acrylate) (poly(EGDMA-co-AcNa)) particles were effectively self-assembled on poly(divinylbenzene-co-styrylmethyl trimethyl ammonium chloride) (poly(DVB-co-StMTMACl)) surfaces to result in core-corona composite particles with a raspberry-like structure by an electrostatic interaction through an affinity complex between sodium acrylate and quaternary ammonium chloride group. The effect of salt electrolyte on the morphology of the raspberry-like polymer composites was investigated by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The zeta-potential (xi) values of poly(DVB-co-StMTMACl) core, poly(EGDMA-co-AcNa) corona, and raspberry-like composite were determined by zeta-potential analyzer. The water static contact angle on the surfaces of polycarbonate (PC) film with micro-nano binary roughness originated from raspberry-like particles was investigated on a contact angle system.
