NOVELTY - Preparing high-performance electrically driven IPMC flexible driver comprises e.g. (1) mixing C-CNC cellulose solution, distilled water, and 1-ethyl-3-methyl ionic liquid to form a mixed solution; (2) sealing the mixed solution and stirring; (3) adding graphene to the mixed solution, first ice bath and shaking the ice bath time; (4) sealing the mixed solution and stirring; (5) subjecting the mixed solution to ultrasonic treatment; (6) vacuum drying the mixed solution, where the vacuum drying; (7) pouring the solution into the mold, vacuum drying and allowing to stand the mold at room temperature to obtain substrate exchange membrane, and removing the substrate exchange from the mold membrane; (8) pouring the C-CNC cellulose solution into the mold, and vacuum drying obtain electrode film, and taking out the electrode film; and (9) cutting the electrode membrane and the substrate exchange membrane into the same shape, and heating press. USE - The method is useful for preparing high-performance electrically driven IPMC flexible driver. ADVANTAGE - The method has fast response, large deformation, high performance of the driver. DETAILED DESCRIPTION - Preparing high-performance electrically driven IPMC flexible driver based on C-CNC cellulose, comprises (1) mixing 20-25 pts. wt. C-CNC cellulose solution, 30-35 pts. wt. distilled water, and 0.5 pts. wt. 1-ethyl-3-methyl ionic liquid to form a mixed solution; (2) sealing the mixed solution and stirring for 3-4 hours; (3) adding 0.5-0.6 pts. wt. graphene to the mixed solution, first ice bath and shaking the ice bath time for 10-20 minutes, where the shaking temperature is 25-35 degrees C, and the shaking time is 240-300 minutes; (4) sealing the mixed solution and stirring for 0.5-1 hours; (5) subjecting the mixed solution to ultrasonic treatment for 60-120 minutes, and the ultrasonic treatment temperature is 35-45 degrees C; (6) vacuum drying the mixed solution, where the vacuum drying time is 24-50 minutes, and the vacuum drying temperature is 45-55 degrees C; (7) pouring the solution into the mold, vacuum drying at 45-55 degrees C for 16-24 hours, and allowing to stand the mold at room temperature to obtain substrate exchange membrane, and removing the substrate exchange from the mold membrane; (8) pouring the C-CNC cellulose solution into the mold, vacuum drying at 45-55 degrees C for 16-24 hours, and allowing to stand the mold at room temperature to obtain electrode film, and taking out the electrode film; and (9) cutting the electrode membrane and the substrate exchange membrane into the same shape, placing a piece of substrate exchange membrane between the two electrode membranes, and heating press for 6-8 hours.
