Problems solved by technology

However, since the carbon nanotubes 12 in the nano-flexible electrothermal material 10 are prone to agglomeration, the dispersion of the carbon nanotubes 12 in the nano-flexible electrothermal material 10 is not uniform enough
Therefore, the response rate, conductivity and stress of the nano-flexible electrothermal material 10 need to be further improved.

Abstract

The invention relates to an electrostrictive composite material comprising a flexible macromolecule base, a plurality of carbon nano tubes distributed in the flexible macromolecule base and a plurality of ceramic particles distributed in the flexible macromolecule base. Besides, the invention also relates to a preparation method of the electrostrictive composite material.

Description

technical field [0001] The invention relates to an electrostrictive composite material and a preparation method thereof, in particular to an electrostrictive composite material containing carbon nanotubes and a preparation method thereof. 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...
