Problems solved by technology

[0003] Traditional IPMC is mainly made of precious metals such as Pt and Au through repeated electroless plating. This preparation method not only has high cost and long production cycle, but also when working in a non-aqueous environment, the water in the membrane is easily electrolyzed, making it Unstable actuation performance
In recent years, Pt-Ni composite electrodes and other types of IPMC have been widely studied. Although IPMC with composite electrodes has good actuation performance and saves production costs, the electrodes are easily oxidized in the air, which greatly limits the wide application of this type.

Embodiment 1

[0043] The scanning device used in the embodiment is EPMA, the model is JXA-8530F.

[0044] The butyl rubber used for encapsulation was purchased from the market and prepared in a ratio of 1:2 with molecular weights of 2000 and 5000.

[0045] A kind of preparation method of IPMC actuator, comprises the steps:

[0046] (1) Electroless platinum plating

[0047] Take the Nafion117 membrane with a thickness of 0.2 μm. First, polish the Nafion117 membrane with 1200# sandpaper to a thickness of 0.17 μm; then use ultrasonic cleaning for 10 minutes, and then boil with 2mol / L dilute hydrochloric acid and deionized water for 30 minutes;

[0048] What ion adsorption adopts is dichlorotetraammine platinum (chemical formula: [Pt(NH 3 ) 4 ] Cl 2 ) solution, soak the pretreated basement membrane in a beaker containing the solution for 24 hours to form a soaked basement membrane with a size of 5cm×6cm, and soak the Pt in the basement membrane 2+ The content is 3mg / cm 3;

Abstract

The invention discloses a manufacturing method of an IPMC (ionic polymer-metal composite) actuator, and belongs to the technical field of function materials. The manufacturing method which comprises the steps of chemical platinum plating and copper electroplating is adopted, and the copper pyrophosphate electroplating technology is adopted by electroplating. In order to avoid the phenomenon that due to the fact that a copper electrode is prone to oxidizing in the air, a plating layer falls off, butyl rubber and polydimethylsiloxane are adopted to package a Cu-Pt type IPMC. After packaging is accomplished, the IPMC actuator is obtained. The method is easy to operate. The manufactured IPMC actuator has the actuation performance which is stable, controllable and high in repeatability, the practical application requirement can be met, the off-water working time is prolonged, the IPMC actuator also has the stable output response when the IPMC actuator is placed in the air for 22 days, and the IPMC actuator has the high application value.

Description

Technical field: [0001] The invention belongs to the technical field of functional materials, and in particular relates to a preparation method of an IPMC actuator. Background technique: [0002] IPMC (ionic polymer-metal composites), full name ionic polymer metal composite material, is an ionic EAP (Electro Active Polymer) material, which has good actuation performance, no noise, low density, low driving voltage and good toughness Etc. IPMC is a "sandwich" material composed of basement membrane and metal plating on both sides. Because it can be bent by applying an electrical signal, the actuation mechanism is similar to that of muscle, so it is also called "artificial muscle". Compared with ordinary drives, actuators made of IPMC do not need transmission mechanisms such as bearings and gears, which improves the energy conversion rate and makes many scientific fantasies come true. [0003] Traditional IPMC is mainly made of precious metals such as Pt and Au through repeate...
