Elastic conducting film material and preparation method thereof

Abstract

The invention provides an elastic conducting film material and a preparation method thereof. The preparation method of the elastic conducting film material comprises steps as follows: an elastic film is selected as an elastic attaching base body, certain pull force is applied to two ends of the elastic film, the elastic film is stretched to certain elongation and then fixed, the surface of the elastic film is coated with a liquid elastomeric adhesive, and an adhesive layer is formed; a flexible nano conducting film is pressed on the adhesive layer; the upper side of the flexible nano conducting film is coated with resin with a protection function, so that the adhesive and the resin are cured; the pull force applied to the elastic attaching base body is released, the flexible nano conducting film is driven to retract, and the elastic conducting film material can be prepared. The prepared conducting film material has the characteristics of certain elasticity, good flexibility, stable electrical property and the like; a carbon nanotube film is protected in a resin coating manner, wearing and electric leakage are not easily caused, and the electric safety and the durability of the material are improved.

Description

technical field [0001] The invention relates to the technical field of conductive materials, more specifically, to the field of elastic conductive composite films. Background technique [0002] In recent years, with the development of light and thin electronic devices and the demand for smart wearable conductive materials, traditional rigid electronic devices have become increasingly unable to meet the needs of the modern electronics industry, and conductive films are relatively thin in the market. The application is more and more extensive. However, the current conductive films are generally prepared on hard substrates such as glass and ceramics. The substrate itself has disadvantages such as brittleness, poor elasticity, and not easy to deform. Therefore, the prepared conductive film has poor flexibility and is not resistant to bending and compression. , the wearable performance is poor, and most of them use conductive fillers or coating coatings, and the preparation proc...

[0002] In recent years, with the development of thinner and lighter electronic devices and the demand for smart wearable conductive materials, traditional rigid electronic devices have become increasingly unable to meet the needs of the modern electronics industry, and conductive films are relatively thin in the market. more and more applications

However, the current conductive films are generally prepared on hard substrates such as glass and ceramics. The substrate itself has disadvantages such as brittleness, poor elasticity, and not easy to deform. Therefore, the prepared conductive film has poor flexibility and is not resistant to bending and compression. , poor wearable performance, and most of them use conductive fillers or coating coatings, the preparation process is relatively complicated, which greatly limits its application
