Investigators from University of Lyon Target Chemical Engineering (Multifunctional surfaces from multi-step generation of silver thiolate)

July 2, 2014

By a News Reporter-Staff News Editor at Journal of Engineering -- Investigators publish new report on Chemical Engineering. According to news reporting originating in Ecully, France, by VerticalNews journalists, research stated, "In this article, a novel methodology is studied for making multifunctional surfaces with multilayers of silver thiolate complexes. The method consists, first, in the catalytic generation of a silver thiolate film (first generation) from immersion of silver nanoparticles on a ZrO2-coated substrate in a thiol solution."

The news reporters obtained a quote from the research from the University of Lyon, "Then, successive steps of sample immersion in silver nitrate and in thiol solutions lead to silver thiolate layers of higher generations. The specificity of these latter layers is a much bigger grain size than the one in the layer of the first generation, owing to a new mechanism of formation. This property is used for building superhydrophobic and transparent coated substrates. Owing to sol-gel deposition of ultrathin ZrO2 layers, the anti-reflective effect of the silver perfluorodecanethiolate layers diminish the light reflection on the silica substrate."

According to the news reporters, the research concluded: "It is also shown that other functionalities can be added to the surface with the successive use of thiol solutions of different nature."
