Abstract

The invention discloses a preparation process of a palladium electrode ion polymer and metal composite, which is used for preparing a palladium metal electrode IPMC (Ion Polymer Metal Composite) by using immersion reduction plating and chemical plating methods in which an ion exchange membrane is used as a matrix material and [Pd (NH3)4] C12 is used as a main salt. The preparation process comprises the following four main steps of: (1) pretreatment of the matrix membrane: carrying out roughening, surface cleaning, foreign ion removal and full swelling on the matrix membrane; (2) immersion reduction plating including two processes, i.e., ion exchange and ion reduction: subjecting a pretreated Nafion membrane to repeated palladium ion immersion and exchange, and reducing the pretreated Nafion membrane with NaBH4 by adopting ultrasonic waves to form palladium metals on the surface and the internal surface of the ion exchange membrane; (3) chemical plating: wherein the thickening electrodes on the outer surface of a core material to compact internal surface electrodes by using an improved chemical plating method; and (4) postprocessing of the composite. The preparation process has a higher popularization value due to relatively improved efficiency, relatively lower cost and excellent actuation response.

Description

technical field

[0001] The invention relates to a preparation method of a palladium electrode type ionic polymer-metal composite material, in particular to a chemical preparation method for improving the performance of the material and improving the process flow and process parameters. Background technique

[0002] Ionic polymer-metal composites (IPMCs), a typical ionotropic electroactuated polymer, are a new class of smart materials with both sensing and actuation functions. Compared with other similar materials, IPMC has outstanding advantages such as light weight, low driving voltage, good flexibility, and rapid response. All show broad application prospects. IPMC material is composed of ion exchange membrane core layer material and metal electrode layer material, which is usually formed by combining the electrode layer and ion exchange membrane by physical or chemical methods. The applicant has applied for an invention patent on the basic preparation process of Pd-Nafi...
