Benefits of technology

This new type of rubber-like polymer has several technical advantages over existing materials that are currently available: it's easier to work with compared to other types like plastic or metal; its properties can be controlled easily by adjusting certain parameters such as temperature during manufacturing process (temperature) which makes them more effective at transmitting force without losing their shape when compressed).

Problems solved by technology

The technical problem addressed in this patented text relates to finding an effective way to make stronger electrically conductive polymer films that can withstand higher voltages without losing their effectiveness due to being too soft at room temperature compared to traditional rubber-based products like gloves made from these plugs.

Abstract

Dielectric elastomer material and a preparation process thereof relate to the dielectric elastomer material and the preparation process thereof, which solves the problems existing in the current dielectric elastomer material of low dielectric constant, low deformation, voltage which is exerted to deform close to the disruptive voltage of material. The dielectric elsastomer material is prepared by plasticizer, catalyst and virgin rubber of silicon rubber in silicon resin BJB TC 5005 and relaxation-type ferro-electricity ceramic material. The preparation process comprises firstly agitating raw materials under constant temperature except relaxation-type ferro-electricity ceramic material, then adding relaxation-type ferro-electricity ceramic material to agitate under constant temperature again, and conducting solidification treatment for prepared substances after poured into patternmaking dies. The dielectric elastomer material of the invention has high dielectric constant, large deformation, and voltage for deformation is far lower than the disruptive voltage of the dielectric elastomer material of the invention. The preparation process of the invention is simple, and is easy to be operated, and technique is easy to control.
