采用基于聚苯乙烯乳胶球的自组装胶体模板制备了三维高有序大孔导电聚合物薄膜。聚（吡咯），聚（苯胺）和聚（二噻吩）通过电化学聚合，聚合物通过聚（苯乙烯）乳胶球（直径0.5或0.75微米）之间的间隙生长，在金衬底上自组装成紧密排列的阵列。乳胶球模板随后在甲苯中溶解去除。从扫描电子显微镜研究中可以看出，导电聚合物薄膜中有规则的孔径和相互连接的通道。所研究的导电聚合物的孔径与用作模板的聚苯乙烯球的尺寸有关。在一些聚合物的研究中发现了结构收缩的证据。
Three-dimensional highly ordered macroporous conducting polymer films were prepared using a self-assembled colloidal template based on poly(styrene) latex spheres. Poly(pyrrole), poly(aniline) and poly(bithiophene) were polymerised electrochemically and the polymer grown through the interstitial spaces between poly(styrene) latex spheres (0.5 mum or 0.75 mum in diameter) self-assembled in a close-packed array on gold substrates. The latex sphere template was subsequently removed by dissolution in toluene. Regular pore sizes and interconnected channels within the conducting polymer films were evident from scanning electron microscopy studies. The pore sizes for the conducting polymers studied were related to the dimensions of poly(styrene) spheres used as the template. Evidence for shrinkage of the structure was found for some polymers studied.
