METHOD FOR STRUCTURING A TRANSPARENT CONDUCTIVE MATRIX COMPRISING NANO MATERIALS

摘要

The present invention refers to a method for selectively structuring of a polymer matrix comprising AgNWs (silver nano wires) or silver nano particles (Ag nano ink) or comprising mixtures of AgNWs and silver nano particles on a flexible plastic substructure or solid glass sheet. The method also includes a suitable etching composition, which allows to process the method in an industrial scale.

主权项

1. A method for selective decomposition and release of silver nanowires (AgNWs) and/or of silver nano particles, which are comprising within a polymer matrix, which in turn is positioned on a flexible plastic or glass substructure, comprising the steps:
a) printing an etching paste onto the surface of a composite material comprising the polymer matrix comprising silver nanowires (AgNWs) on a plastic substrate or glass sheet, b) etching for a predetermined period of time (fixed dwell time) with or without heating and c) cleaning the substrate surface, with the proviso that the polymer matrix remains and shows a porous structure.without removal of the polymer matrix
