Abstract

The invention discloses a flexible stretchable conductive material and a device and method for manufacturing the same. A material comprise an elastic matrix, a flexible stretchable conductive mesh, and a plurality of conductive spiral monomers which are arrange in parallel in a row-column manner and are connected into a conductor end-to-end. The method comprises the following steps of: dropping amixture of a conductive helical monomer and an organic solvent onto a metal mask, and low-frequency reciprocating oscillation; Placing a composite body filled with conductive spiral monomer in a heating furnace for heat treatment and welding to form a conductive spiral bundle; Cooling to room temperature; Take out that conductive spiral beam and putting it into a forming die for compaction; Pouring a liquid elastic matrix into the compacted forming die; The flexible stretchable conductive material is obtained by heat curing and demoulding. The invention can effectively avoid the problem of stress concentration and prolong the service life of the material. And the problem of material failure caused by separation of microstructure from elastic matrix after repeated mechanical deformation issolved.

Description

technical field [0001] The present invention relates to the technical field of conductive material production, in particular to a flexible and stretchable conductive material based on a microhelical structure and its production device and method. Background technique [0002] Flexible and stretchable conductive materials can still maintain stable conductive properties under mechanical stretching or bending, so they show great application prospects in flexible electronics, smart wear, and the Internet of Things. At the same time, their design and manufacturing technologies are also It has always been a research hotspot in the field of new materials. Among them, the use of deformable microstructures to manufacture flexible conductive materials is an important research field. The basic principle is to use deformable microstructures to achieve stretching and bending deformation while maintaining stable conductivity. At present, these materials are generally based on two-dimensi...
