Preparation method of high-conductivity tensile strain response material

Abstract

The invention discloses a preparation method of a high-conductivity tensile strain response material, and belongs to the technical field of semiconductor sensor materials. The preparation method comprises steps as follows: firstly, a CNT(carbon nano tube) / graphene hybrid material is prepared, then CNT / graphene is uniformly dispersed in a solution of a high polymer material by a homogenizer throughultrasonic oscillation, and finally, a CNT@graphene / polymeric nanocomposite, namely, the high-conductivity tensile strain response material, can be prepared with a solution pouring film formation ordip-coating method. The prepared material has high conductivity, better flexibility and good strain response capacity. The preparation method is simple, low in cost and high in applicability, can be applied to large-scale production and can be widely applied in industries such as smart skin, pressure-sensitive sensors and the like.

Description

technical field

[0001] The invention belongs to the technical field of semiconductor sensor materials, and in particular relates to a preparation method of a highly conductive tensile strain response material. Background technique

[0002] Graphene is a two-dimensional nanomaterial composed of a single layer of carbon atoms, which has a large specific surface area, high electrical conductivity, and good mechanical properties and other functional properties. As a one-dimensional nanomaterial, carbon nanotubes have high aspect ratio, light weight, perfectly connected hexagonal structure, and many excellent mechanical, electrical, and chemical properties, and have a wide range of applications.

[0003] The conductive composite material prepared by dispersing the conductive filler into the non-conductive polymer matrix will restructure the internal conductive path under the action of external force, and has certain force-sensitive properties. Due to its good flexibility and pro...
