Carbon nanotube fiber-ionic gel artificial muscle and electric actuating performance testing method thereof

Abstract

The invention discloses a carbon nanotube fiber-ionic gel artificial muscle and an electrodeformation test method thereof, and belongs to the technical field of electrochemical actuation performance test. The artificial muscle is mainly prepared from carbon nanotube fibers and ionic gel under certain conditions. According to the invention, two electrodes of the artificial muscle are electrified through a power supply, and a displacement sensor and a data collection box are used for measuring the electrodeformation shrinkage amount of electrified fiber; by adding graphene, the conductivity of the artificial muscle is increased, so that the electric actuating performance is improved; salt with moisture retention capacity is dissolved in the gel, and the gel is coated with an elastomer layerwith water retention capacity, so that the service life of the artificial muscle is prolonged, and the artificial muscle is driven in a gas or liquid environment compared with carbon nanotube fibers;and the artificial muscle has the advantages of being high in conductivity, high in energy conversion efficiency, excellent in mechanical property, wider in application environment and the like, and has wide application in the fields of medical treatment and public health, industrial product manufacturing, robot research and development and the like.

Description

technical field [0001] The invention relates to the technical field of electrochemical actuation performance testing, in particular to a carbon nanotube fiber-ion gel artificial muscle and a method for testing the electrical actuation performance thereof. Background technique [0002] In recent years, artificial muscles have received extensive attention and research because of their advantages such as light weight, convenient process, and good flexibility. Artificial muscle is a new type of material that responds to external stimuli and produces different deformations through different structures. As people have higher requirements for the performance of artificial muscles, the requirements for the performance of the electric actuation material as its core part are also higher, but at present, the mechanical properties and electrical conductivity of most materials cannot be balanced, and there are fractures and damages during use. , Low room temperature conductivity, poor d...

Problems solved by technology

As people have higher requirements for the performance of artificial muscles, the requirements for the performance of the electric actuation material as its core part are also higher. However, at present, the mechanical properties and electrical conductivity of most materials cannot be balanced, and there are fractures and damages during use. , low room temperature conductivity, poor driving performance, etc.

At the same time, when the artificial muscle is driven in a gas or liquid environment, it is greatly restricted in the actual application process.
