将N-异丙基丙烯酰胺与乙烯基二茂铁(13：1)进行共聚，在电极上涂覆一层共聚物膜。共聚物膜发生了热诱导体积相变，在高于或低于相变温度(Tt)时，膜在水介质中分别发生收缩或膨胀。膨胀膜中均匀电荷输运的表观扩散系数至少是收缩膜中的5倍。在膨胀和收缩状态之间，薄膜的表观形式势也是不同的
N-Isopropylacrylamide was copolymerized with vinylferrocene (13:1), and an electrode was coated with a film of thus obtained copolymer. The copolymer film showed thermally induced volumetric phase transition; at higher or lower temperatures than the transition temperature (T t ), the film is shrunken or swollen, respectively, in aqueous media. The apparent diffusion coefficient for the homogeneous charge transport in the swollen film is at least 5-fold larger than that in the shrunken film. The apparent formal potential of the film is also different between the swollen and shrunken states
