Problems solved by technology

However, there are still a series of problems in the current production of conductive paper, such as (1) the high Young's modulus of the hard conductive filler, which leads to the tendency of the paper fiber to fall off during the bending process, and the resistance rises significantly after repeated bending (2) Some metal powders have the problem of oxidation, which greatly reduces the conductivity of the paper; (3) After some carbon-based conductive materials are combined with the paper, the transparency of the paper is greatly reduced or completely black

In addition, most of the existing high-transparency conductive paper preparation processes use physical deposition methods to control the thickness of the conductive layer within 50nm to obtain high transparency. However, the complicated deposition process requires harsh high-pressure, vacuum or high-temperature conditions. High consumption and low output limit the practical application of conductive paper

These problems have greatly limited the further expansion of the application field of conductive paper.
