钯-聚吡咯复合薄膜已经使用三种不同的自下而上的程序合成，所有程序都包括钯纳米颗粒的电化学合成，所述钯纳米颗粒随后恒电位沉积或嵌入到电化学产生的聚吡咯薄膜中。所得复合材料的透射电子显微照片显示，金属夹杂物具有约5 nm的平均直径，具有均匀的尺寸分布。实验证明，纳米粒子和复合薄膜都具有电活性。这种方法的可扩展性的其他金属-聚吡咯材料（即银-聚吡咯复合材料）的电合成的初步结果也被提出。(C)2000 Elsevier Science S.A. All rights reserved.
Palladium-polypyrrole composite thin films have been synthesised using three different bottom-up procedures all comprising the electrochemical synthesis of palladium nanoparticles that are subsequently potentiostatically deposited or embedded into an electrochemically produced polypyrrole thin film. Transmission electron micrographs of the resulting composites show that the metallic inclusions have a mean diameter of about 5 nm with a homogeneous size distribution. Experimental evidence is also provided that both the nanoparticles and the composite thin films are electroactive. Preliminary results on the extendibility of this approach to the electrosynthesis of other metal-polypyrrole materials (namely Ag-PPy composites) are also presented. (C) 2000 Elsevier Science S.A.
