Problems solved by technology

In addition, with the development of thinner and thinner 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 widely used in the market due to their thinner and thinner more and more widespread
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

Abstract

The invention relates to a conductive composite film comprising a carbon nanotube / graphene / polyaniline composite film, wherein the upper surface and the lower surface of the composite film are loaded with resin and both ends are adhered by electrodes. The preparation of the film is realized through the following steps: immersing a layer of carbon nanotube film in graphene suspension; taking it out and having it dried for a carbon nanotube / graphene composite film; obtaining a nanotube / graphene / polyaniline composite film by in-situ growth of polyaniline nanowire arrays on the surface of carbon nanotube / graphene composite film; adhering electrodes at two ends of the nanotube / graphene / polyaniline composite film; and coating and solidifying the upper surface and the lower surface of the film with resin. A flexible conductive film can be used in smart textiles as both a conductive material and a flexible electronic device. The conductive film material prepared by the invention has good conductivity reaching from 103S / m to 105S / m, and can bear certain bending and compression deformation.

Description

technical field [0001] The invention belongs to the field of composite film material and its preparation and application, in particular to a conductive composite film and its preparation and application. Background technique [0002] Traditional conductive materials are generally metal materials, but in recent years, with the development and progress of science and technology, some non-metallic conductive materials have developed rapidly and have been widely used in the fields of electronic power, communication, energy and so on. In addition, with the development of thinner and thinner 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 widely used in the market due to their thinner and thinner more and more widely. However, the current conductive films are generally prepared on hard substrates such as gla...
