Problems solved by technology

However, the vast majority of current polymer materials will undergo serious deterioration at high temperatures, and may even cause extreme situations such as smoke and fire
[0011] Studies have shown that when the hollow network structure is fused at a certain point, a chain reaction will quickly occur, causing the collapse of the entire transparent conductive network, and accidents will occur
[0012] All in all, the conductive powder in traditional products will be damaged / shedding at high temperature (eg 150-600°C)
And some heat-labile auxiliary materials (such as some resin materials) even have the risk of fire
On the other hand, the damage of the conductive part will further cause the product to heat up, thus forming a vicious circle

Description

technical field [0001] The invention relates to the technical field of conductive shielding structures, in particular to a high-temperature-resistant transparent conductive shielding structure and a preparation method thereof. Background technique [0002] In the past few decades, light-transmitting conductive materials can be divided into two types: continuous type and aperture type based on the basic working principle. The former is mainly a light-transmitting thin film material, such as indium tin oxide (ITO), ultra-thin metal, graphene, transparent conductive polymer, etc.; the latter uses opaque materials to form small pores to achieve light transmission. Effects, such as metal orifice plates, wire mesh, metal nanowires, carbon nanotubes, metal grids, etc. Among them, the continuous light-transmitting conductive film requires that the material itself has both ideal conductivity and light transmission. When the index requirements are strict, the range of available mate...
