在硅橡胶基体中分散均匀

通过调节KH550和TiO

的加入量

提高了介电常数

并使介电损耗保持在一个较低范围

弹性模量相对较低

提高了材料的电致形变性能。

Abstract

Dielectric elastomer material is a new type of smart materials that can be widely used in sensors and actuators. The electrostriction is a crucial characteristic of the dielectric elastomer

which is affected by its dielectric constant and elastic modulus. Silicone rubber has low dielectric elastic modulus and fast strain response

but its electrostriction is small. Based on this situation

the modified TiO

/silicone rubber dielectric elastomer composite material was prepared with silicone rubber as the matrix and KH550 modified TiO

as the filler

with its tensile properties

dielectric properties and electrostriction being tested. It is found that the addition of KH550 enables TiO

to be uniformly dispersed in the silicone rubber matrix. By changing the content of KH550 and TiO

added

the dielectric constant is increased

the dielectric loss is kept low

the elastic modulus is low

and the electrostriction is improved.
