[0018] The preparation method of the electro-responsive three-dimensional carbon nanotube enriched conductive double network polymer hydrogel of the present invention comprises the following steps in sequence:
[0019] The first step is to immerse the foamed nickel in the carbon nanotube water-based slurry, and vacuumize the carbon nanotube water-based slurry to fill the foamed nickel. This process is repeated 1 to 5 times, and then dried to obtain the carbon nanotube-loaded foamed nickel;
[0020] In the second step, sodium montmorillonite, carbon nanotube aqueous slurry, acrylic acid, 2-acrylamido-2-methylpropanesulfonic acid, N, N'-methylenebisacrylamide and initiator are added to Mix evenly in deionized water to obtain hydrogel precursor mother liquid A;
[0021] The third step is to immerse the carbon nanotube-loaded nickel foam obtained in the first step into the hydrogel precursor mother liquid A obtained in the second step, and vacuumize the hydrogel precursor mother l...

[0031] Nickel foam is immersed in the carbon nanotube water-based slurry (carbon nanotube content 2.3wt%, slurry solid content 3.6%, dispersant content 1.26wt%, the same below), vacuumizes the carbon nanotube water-based slurry to be full of foam nickel and then dried. This process was repeated 5 times to obtain carbon nanotube-loaded nickel foam. 1.5 grams of sodium montmorillonite, 26 grams of carbon nanotube aqueous slurry, 3.1 grams of 2-acrylamido-2-methylpropanesulfonic acid, 9.7 grams of acrylic acid, 0.23 grams of N,N'-methylenebispropene Amide and 0.2 g of potassium persulfate were added to 25 g of deionized water and stirred to obtain a hydrogel precursor mother liquid A. Then, immerse the carbon nanotube-loaded nickel foam into the hydrogel precursor mother liquid A, vacuumize the hydrogel precursor mother liquid A to fill the carbon nanotube-loaded nickel foam, and then heat to 60 ° C for 8 hours of polymerization reaction to obtain Poly(2-acrylamido-2-methylpropa...

[0033] Nickel foam is immersed in the carbon nanotube water-based slurry (carbon nanotube content 2.3wt%, slurry solid content 3.6%, dispersant content 1.26wt%, the same below), vacuumizes the carbon nanotube water-based slurry to be full of foam nickel and then dried. This process was repeated three times to obtain carbon nanotube-loaded nickel foam. 2.1 grams of sodium montmorillonite, 20 grams of carbon nanotube aqueous slurry, 6.1 grams of 2-acrylamido-2-methylpropanesulfonic acid, 5.7 grams of acrylic acid, 0.23 grams of N,N'-methylenebispropene Amide and 0.2 g of ammonium persulfate were added to 25 g of deionized water and stirred to obtain a hydrogel precursor mother liquid A. Then, immerse the carbon nanotube-loaded nickel foam into the hydrogel precursor mother liquid A, vacuumize the hydrogel precursor mother liquid A to fill the carbon nanotube-loaded nickel foam, and then heat to 80 ° C for 5 hours of polymerization reaction to obtain Poly(2-acrylamido-2-methylpr...
