Problems solved by technology

However, there are still some limitations. For example, the structure of the actuator is relatively simple, and most of them are laminated with double-layer materials. Therefore, the actuator can only bend to the side with a small amount of thermal expansion, and the bending direction is single, which is difficult to meet Today's Diverse Demands for Actuators

Abstract

The invention discloses an electric actuation material, which comprises a first composite layer, a second composite layer and a matrix material layer, the first composite layer comprises a first material layer and a first adhesive layer, and the first material layer is passed through a first adhesive layer. The binder layer is stacked on the surface of one end of the base material layer; the second composite layer includes a second material layer and a second adhesive layer, and the second material layer is stacked on the other end of the base material layer through the second adhesive layer. Surface; the coefficient of thermal expansion of the first and second material layers is greater than that of the base material layer, the first and second material layers are both polymer material layers, and the base material layer is a carbon-based material layer. The electrical actuation material of the present invention has good flexibility and good electrical and mechanical properties of carbon-based materials, and is easy to prepare. The electric actuator based on the electric actuator material of the present invention responds quickly and has a large degree of deformation, which can realize bending in a specific direction at a specific position and widen the diversity of the actuator.

Description

technical field [0001] The invention relates to the field of electric actuation materials, in particular to electric actuation materials and electric actuators. Background technique [0002] The working principle of the actuator is to convert other energy into mechanical energy. There are three ways to achieve this conversion: through electrostatic field into electrostatic force, that is, electrostatic drive; through electromagnetic field into magnetic force, that is, magnetic drive; using materials Thermal expansion or other thermal properties effect the conversion of energy, ie thermal actuation. [0003] The use of thermally driven actuators overcomes the shortcomings of small deformation of electrostatically driven and magnetically driven actuators. As long as the actuator structure can ensure a certain amount of heat energy, it can produce corresponding deformation. In addition, compared with electrostatic force and magnetic force , the thermal driving force is larger....
