Abstract

The invention provides an ionic rubber elastic body, which comprises: 10% to 95% of a rubber matrix material; 1% to 80% of a liquid ionic material; and a nano powder material 0.1% to 50%; additives 0% to 30%. The ionic rubber elastic body provided by the present invention is added with nano-powder material. The nano-powder material has a high specific surface area and can be uniformly dispersed in the rubber matrix material; meanwhile, because the surface of the nano-powder material contains hydroxyl groups, it is very Strong, so it has good compatibility with liquid ionic materials, the liquid ionic materials can be coated on the surface of nano-powders, and the uniform dispersion of liquid ionic materials in rubber matrix materials can be realized through the loading of nano-powder materials , so that the original difficult-to-mix liquid ionic material and rubber matrix material are functionally compounded to obtain high ion conductivity and high capacitance per unit area.

Description

technical field [0001] The invention belongs to the technical field of sensors, and in particular relates to an ionic rubber elastic body and a preparation method thereof, and an ionic electronic skin. Background technique [0002] Skin plays an extremely important role in the process of human interaction with the outside world. Through the multiple sensory capabilities of the skin, people can feel the tingling of needles, the stimulation of flames and ice, and can easily distinguish the surface of glass, fabric and rubber. However, for people with damaged skin tissue or amputee, the sensory function of their skin is destroyed, and their quality of life will be greatly reduced. Existing artificial mechanical prosthetics can already simulate the appearance and various mechanical functions of the original limbs very well, and when the sensory function of the skin is added to the mechanical prosthetics, it can restore various external perception capabilities of the prosthetics...
