Abstract

The invention provides an electrostrictive composite as well as a preparation method and an application thereof. The electrostrictive composite is prepared from 50%-60% of polyether type TPU particles, 5%-10% of carbon nanotubes, 10%-20% of biomass graphene, 10%-20% of nano barium titanate, 1%-5% of nanosilver particles and 5%-15% of glass fiber. Components mutually cooperate and have a synergistic effect, so that the electrostriction rate of the electrostrictive composite can be up to 24.1%-26.8%, and the composite can be applied to the field of functional materials and has a good application prospect.

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.
