preparation example Construction

[0032] A preparation method of perfluorosulfonic acid artificial muscle, the materials required for the experiment include:

[0033] Nafion117 film (DuPont), SPI conductive silver glue (43wt%, 10mL), SPI conductive carbon glue (40wt%, 10mL), deionized water 500mL, hydrogen peroxide (30wt%, 20mL), concentrated sulfuric acid (98wt%, 1mL), lithium chloride (purity 99%, 10g);

example 1

[0035] The preparation steps of selecting SPI conductive silver glue as the electrode are as follows:

[0036] 1. The pretreatment process of Nafion membrane

[0037] A commercial Nafion ion-exchange membrane was selected, and the Nafion ion-exchange membrane was a Nafion117 film produced by DuPont Company with a thickness of 190 μm, which was cut into a rectangle with a length of 50 mm and a width of 20 mm.

[0038] Soak the transparent Nafion membrane in 50 mL of 5% hydrogen peroxide aqueous solution for 4 hours, then soak the Nafion membrane in deionized water and heat to boil for 1 hour. Afterwards, soak the Nafion film in 50 mL of 5% sulfuric acid solution for 4 hours, then soak the Nafion film in deionized water and heat to boil for 1 hour.

[0039] After pretreatment, the Nafion film fully absorbs water and swells, and presents a soft and transparent shape.

Abstract

The invention discloses a preparation method of perfluorosulfonic acid artificial muscle, comprising the following steps: 1. a pretreatment process of Nafion membrane; 2. a preparation process of electrodes; 3. an ion exchange process of Nafion membrane. The preparation period of the perfluorosulfonic acid artificial muscle of the present invention is shortened by 80%, the cost is reduced by 30%, and the excellent performance is still maintained. It can grab a maximum weight of 8g, which is 20 times its own weight.

Description

technical field [0001] The invention relates to the technical field of new intelligent materials, in particular to a preparation method of perfluorosulfonic acid artificial muscle. Background technique [0002] Artificial muscle is a new type of material with driving performance. At present, artificial muscles developed earlier include pneumatic artificial muscles and hydraulic artificial muscles. These two artificial muscles generate greater driving force by filling or pumping gas or liquid. However, both artificial muscles require large loads, such as air pumps, liquid pumps, etc., which greatly affect the requirements of artificial muscles in terms of lightness and easy installation, and limit the practical application of artificial muscles. [0003] In the past ten years, the birth of a series of intelligent materials has provided a new development opportunity for the research of artificial muscles. Smart materials refer to materials that can change under external stimu...
