Description

technical field [0001] The invention relates to the field of polymer materials, in particular to an electrostrictive composite material and its preparation method and application. Background technique [0002] Electrostrictive composite material is a kind of material that can produce stretching motion under the action of electric field, so as to realize the conversion of electrical energy to mechanical energy. Electrostrictive composite materials are also known as artificial muscle materials because of their muscle-like motion in the conversion of electrical energy to mechanical energy. Among the materials and devices based on electrostrictive composite materials for electric energy-mechanical energy conversion in the prior art, the electrostrictive composite materials are mainly formed of single-component materials, which have high driving voltage and low output stress , so that there is still a big gap between its performance and muscle.
