Title: METHOD FOR THE LOW-TEMPERATURE PREPARATION OF ELECTRICALLY CONDUCTIVE MESOSTRUCTURED COATINGS
Abstract:
The present invention relates to a method for manufacturing mesostructured coatings comprising electrically conductive structures formed of metal nanoparticles. Said method includes the steps that involve: a) depositing, on a substrate, a first layer consisting of a silica material, mesostructured by a structuring agent, and a photocatalytic material; b) depositing, on the first layer, a second layer of a mesostructured silica material, said second layer being free of photocatalytic material; c) consolidating the first and second layers at a temperature between 50º C and 250º C; and d) placing the consolidated coating in contact with a solution that contains metal ions and irradiating said coating with a radiation that enables the photocatalytic material to be activated. Said method is characterized in that it includes no heat treatment at a temperature greater than 250º C.
