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 ...
