Abstract
IPMC is a new type of polymer material that will act violently to the stimulation of electrical signals. IPMC has changed the traditional mechanical driving mode. However, the development of IPMC is limited by factors like manufacture cost. In order to reduce the manufacture cost of IPMC, improve the output displacement and output force of IPMC, and make IPMC closer to real life, in this paper, we use carbon nanotubes to modify the ion exchange membrane of IPMC, and PDDA to modify carbon nanotubes and graphene. A graphite plated electrode and a carbon nanotube electrode were coated on a platinum plated IPMC. The common modified Pt-IPMC, carbon nanotubes modified Pt-IPMC, carbon nanotubes modified GS-IPMC, and carbon nanotubes modified CNT-IPMC were prepared. Through the experiment, it is found that the maximum output displacement of GS-IPMC modified by carbon nanotubes is 4.9 mm, and the maximum output force is 39 mN. The output displacement of ordinary Pt IPMC is 3.18 mm and the maximum output force is 31 mN. The maximum displacement and output force of GS-IPMC modified by CNTs are higher than those of Pt IPMC, which is more suitable for research and application.

Industrial-grade polydiallyl dimethyl ammonium chloride (PDDA) was purchased from Suzhou Haonuo Industry and Trade Co., Ltd., which was used for package of graphene and electrophoresis of carbon nanotubes; single layer graphene and carbon nanotubes were purchased from Shenzhen Suiheng Graphene Technology Co., Ltd.; Dichlorotetra ammonium platinum was purchased from BiDe Pharmaceutical; Industrial grade methanol was purchased from Yantai Shuangshuang Chemical Co., Ltd; Technological process
The IPMC will be flipped appropriately every time when the reducing solution is added during the electroless plating process, there is a large gap between the electrodes on either side
Summary
Ionic polymer IPMC is a new type of polymer material. IPMC is a polymer material. Compared with conventional actuation materials, it is endowed with the advantages of lightweight, large strain range, low energy consumption, soft structure, good environmental adaptability, strong affinity, and various functions.[1,2,3,4] IPMC has very broad application prospects in the fields of biomimetic soft robots, medicine, aerospace, and underwater research.[5] For example, Bian et al.[6] have designed a bionic mechanical fish drive technology. They use pulse voltage, IPMC rapid response drive technology and spatial stacked structure
