Estimating the term…
The invention relates to a process for improving the electrical and optical performance of a transparent electrically conductive material having silver nanowires. The invention also relates to a process for manufacturing a film made of a transparent electrically conductive material, such as a transparent electrode, a transparent heating film, or a film for electromagnetic shielding. The process of the invention includes the following steps: a) a step of bringing silver nanowires into contact with an acid solution, this solution having a pH lower than 7, preferably lower than 3; and b) a step of eliminating the acid. The field of application of the invention is in particular the field of optoelectronics.
A process for manufacturing a layer made of a transparent electrically conductive material based on silver nanowires, wherein the process comprises:
A process for manufacturing a transparent conductive electrode, comprising a step of bringing silver nanowires into contact with a solution of nitric acid, said solution of nitric acid having a nitric acid content higher than or equal to 0.2% and lower than or equal to 20% by weight of nitric acid relative to the total weight of the solution;
