Abstract

The invention relates to a polyester dielectric elastomer composite material and a preparation method. The cross-linking density of the polyester elastomer is reduced by adopting unsaturated aliphatic polyester synthesized by condensation polymerization of aliphatic glycol, aliphatic diacid and itaconic acid; meanwhile, the composite material with high dielectric constant and low elastic modulus is obtained by adding a high dielectric semiconductor filler; and the composite material can obtain high electro-deformation under very low external field voltage. The problem that the dielectric elastomer in the traditional method generates high electro-deformation under high voltage is solved.

Description

Technical field: [0001] The invention relates to a polyester dielectric elastomer composite material and a preparation method thereof. In particular, it relates to a polyester dielectric elastomer composite material capable of producing large electric deformation under small driving voltage and a preparation method thereof. Background technique: [0002] Dielectric Elastomer (DE) is an electroactive polymer with excellent comprehensive performance, which has large electro-induced deformation, high elastic energy density, fast response time (ms), low dielectric loss and viscoelastic hysteresis loss, With the characteristics of high conversion efficiency, it has broad application prospects in the fields of artificial muscles, biomedicine, micro-robots, planar loudspeakers, and prosthetic organs. [0003] Elastomers have unique high elasticity (short reaction time, small viscoelastic hysteresis), good flexibility and high filling capacity. The induction is weak and cannot be ...
