Preparation method of metal conductive film having flexible substrate

Abstract

The invention discloses a method for preparing a metal conductive film with a flexible substrate. The invention realizes the continuous and large-area production of the flexible conductive film, greatly shortens the production cycle, greatly improves the productivity and reduces the production cost, and solves the problem of the flexible metal film. The problem of large-area continuous production of network transparent conductive films. Metal nanoparticles are grown on top of graphene in situ. This method has a lower contact barrier than simply mixing graphene and metal nanoparticles. Metal nanoparticles The electrons in the graphene are more likely to migrate to the graphene, so that the carriers in the graphene become more, and the graphene itself has a higher carrier mobility, and the graphene and the metal nanoparticles grown on it form a synergistic Enhancement effect, the transparent conductive film prepared by the invention has better conductivity.

Description

technical field [0001] The invention relates to the field of conductive materials, in particular to a method for preparing a metal conductive film with a flexible substrate.
