Process for producing articles having an electrically conductive coating |
摘要 |
The present invention relates to a process for producing articles having on at least part of their surface an electrically conductive coating by at least partly coating a substrate with a composition comprising finely divided electrically conductive metal particles and a binder and subjecting the coated substrate to at least one treatment with water in the presence of a halide ion source at a temperature in the range from ambient temperature to 200° C. The process of the invention allows articles having an electrically conductive coating to be produced in a simple, rapid and mild way. |

1. A process for producing an article having on at least part of its surface an electrically conductive coating, which article is selected from the group consisting of a printed circuit board, RFID antenna, battery and solar cell, wherein the process consists of at least partly coating a substrate with a composition comprising finely divided electrically conductive silver particles and a binder and improving the electrical conductivity of the electrically conductive coating by subjecting the coated substrate to at least one treatment with a composition that consists of water and a halide ion source at a temperature in the range from 50 to 95° C., wherein the composition optionally comprises a water soluble organic or inorganic acid, wherein the halide ion source is selected from an alkali metal halide, an alkaline earth metal halide, an aluminium halide, a zinc halide, and an ammonium halide such that the standardized specific surface resistance of the coating is less than 10 mΩ/25 μm. |
