Embodiment 1

[0035] In this embodiment, SBS is used as the elastomer fiber substrate, dichloroethane is used as the solvent, and gallium indium alloy (Ga 0.685 In 0.215 sn 0.1 , melting point -19°C) as a conductive material, the present invention will be further described through examples, but this should not limit the scope of protection of this patent, all other thermoplastic elastomer materials that can be used for spinning, all soluble thermoplastic elastomers Solvents and liquid metals with a melting point lower than room temperature are suitable for the superelastic yarn with high electrical conductivity and high electrical conductivity stability and the preparation method disclosed in the present invention.

[0036] The present embodiment provides a kind of preparation method of high conductive stability superelastic yarn, comprises the following steps:

[0037] (1) Preparation of spinning solution: dissolving the thermoplastic elastomer material TPE in an organic solvent to obtai...

Embodiment 2

[0051] This embodiment provides a high conductive stability superelastic yarn and a preparation method thereof. The preparation steps are the same as the preparation steps provided in Example 1. The difference is that the surface of the elastic conductive yarn obtained in step (4) is A layer of TPE fiber is coated by electrospinning again to form a coating or protective layer, which changes the type of TPE or liquid metal, as shown in Table 1:

Abstract

The invention discloses a high-conduction-stability superelastic yarn, and a preparation method and application thereof. The preparation method comprises the following steps of (1) preparing a spinning solution, namely dissolving a thermoplastic elastomer material TPE in an organic solvent to obtain the spinning solution; (2) preparation TPE fiber: preparing TPE micro-nano fiber from the spinningsolution obtained in the step (1) through electrostatic spinning, collecting the TPE fiber by using a metal wire in the spinning process, and coating the TPE fiber onto the surface of the metal wire;(3) peeling the TPE fiber coating the surface of the metal wire from the surface of the metal wire, and performing drying to obtain a TPE yarn; and (4) coating liquid metal onto the surface of the dried TPE yarn to obtain an elastic conductive yarn. The preparation method provided by the invention has the advantages that the method is simple; the efficiency is high; the cost is low; and the methodis applicable to mass production. The high-conductivity and high-conduction-stability superelastic yarn can be used for wearable optoelectronic equipment and all other equipment needing to use stretchable conductor materials.
