Problems solved by technology

The literature (S. De et al., Silver nanowire networks as flexible, transparent, conducting films: extremely high DC to optical conductivity ratios, Acs Nano 3 (2009) 1767-1774) reported a new method in polyethylene terephthalate ( The method of preparing silver nanowire conductive layer on PET) film, but the adhesion between silver nanowire and PET is poor, the conductive layer is easily damaged by sticking, and the surface is not flat enough, and the surface fluctuation may be as high as 100 nanometers to 300 nanometers. There is still a considerable gap in practical application

Abstract

The invention provides a structure and a preparation method of a silver nanowire transparent conductive film based on a thermoplastic transparent polymer, which is characterized in that the silver nanowire conductive network is uniformly spread on a hard substrate, and then the The method makes a continuous silver nanowire conductive network embedded on the surface of a thermoplastic transparent polymer, and part of the surface of the silver nanowire is exposed to the air to form a silver nanowire conductive film based on the thermoplastic transparent polymer.

Description

[0001] technical field [0002] The invention provides a structure of a silver nanowire transparent conductive film based on a thermoplastic transparent polymer and a preparation method thereof. Background technique [0003] Transparent conductive film is a functional film with high visible light transmittance and certain conductivity. It is widely used as transparent electrodes in liquid crystal displays, touch screens, electroluminescent devices and thin film solar cells, as well as antistatic coatings and electromagnetic shielding layer. The transparent conductive film can achieve high visible light transmittance and high electrical conductivity at the same time, so it can ensure the simultaneous transmission of visible photons and carriers. So far, the transparent conductive material with the best overall performance is tin-doped indium oxide (ITO), which can achieve a square resistance value of less than 10Ω and a resistivity of less than 1.5×10 when the visible light ...
