Abstract: Provided are composite array electrode, preparation method thereof and use thereof. The composite array electrode comprises a microelectrode array substrate, and a modification layer formed on a surface of a microelectrode of the microelectrode array substrate, wherein the modification layer comprises a plurality of electrically conductive layers arranged at intervals on the surface of the microelectrode, an insulating layer arranged on the surface of the microelectrode except the electrically conductive layers, and wherein material for the electrically conductive layers comprises one or more of nano platinum, nano iridium, conductive polymer and carbon nanotubes. The composite array electrode effectively eliminates the influence of edge effect such that the electric field distributes uniformly on the microelectrode surface of the composite array electrode, significantly improving electrochemical performance and detection capability of the electrode.

Abstract: A method for preparing a flexible electrode is provided. The method comprises sequentially forming a flexible base layer and an intermediate conductive layer on a carrier plate; treating an elastomeric template having an electrode pattern with an acid, followed by transferring and printing the electrode pattern onto the intermediate conductive layer to form an electrode inducing layer; forming a titanium dioxide-polydopamine composite layer in a gap of the electrode inducing layer; forming a platinum electrode layer on the titanium dioxide-polydopamine composite layer; removing the carrier plate. The invention solves the problems of slow formation of a polydopamine film and slow formation of a platinum electrode layer. A flexible electrode is further provided.
