Embodiment Construction
[0009] Such as figure 1 As shown, a dielectric elastomer stack driver manufacturing process includes the following steps: firstly, spraying a single-walled carbon nanotube solution on a dielectric elastomer IPN film. Among them, the production process of IPN film (1) is: pre-stretch the acrylic film and fix it on the metal support frame (2), keep the pre-stretch ratio between 350% and 500%, and configure the IPN reaction agent (m 过氧化苯 :m TMPTMA :m 乙酸乙酯 =10:100:57), use an airbrush to evenly spray the IPN reaction agent on both sides of the polyacrylic film, let it stand for 10h~12h, then put it in a vacuum drying oven for heating. Control temperature: 85℃~90℃, time: 6h~7h, air pressure: -0.07Mpa~-0.09Mpa. After cooling, an IPN film is made. The configuration of the single-wall carbon nanotube solution is: the concentration of the solute single-wall carbon nanotube in the solution is 0.2 mg / ml, and the solvent is isopropanol. After the solution is uniformly dispersed with ...

Description
technical field [0001] The invention belongs to the field of dielectric elastomer driving, and relates to a manufacturing process of a reproducible dielectric elastomer stack driver using single-wall carbon nanotubes as electrodes. Background technique [0002] In recent years, dielectric elastomer actuators, as a kind of artificial muscle actuators, have broad application prospects in aerospace, robotics, and medical fields due to their advantages such as high power density, large electrostrictive deformation, and high energy conversion efficiency. The currently used polyacrylic acid, a dielectric elastomer deformable material, needs to be pre-stretched in both directions. In order to maintain the stretched state, a pre-tensioning mechanism must be provided in the stretching direction. Therefore, ordinary polyacrylic acid films cannot be used for the development of stacked drivers. In terms of research on stacked actuators, the Swiss Federal Materials Testing and Developmen...
