PROCESS FOR DEPOSITING NANOPARTICLES ON A NANO-STRUCTURED METAL-OXIDE SUBSTRATE

摘要

The present invention relates to a process for depositing nanoparticles (NPs) on a nanostructured metal-oxide substrate (NSMO), characterised in that it comprises steps of: a) functionalising the NSMO substrate with a bifunctional coupling agent carrying a first function, this first function being a phosphonic function that forms a bond with the NSMO, and a second function that it intended to form a bond with a nanoparticle; and b) grafting the nanoparticles via a bond to the second function of the coupling agent. The invention also relates to a multilayer comprising a nanostructured metal-oxide substrate covered with nanoparticles by way of a bifunctional coupling agent carrying a first function, this first function being a phosphonic function that forms a bond with the NSMO, and a second function that is intended to form a bond with a nanoparticle. The invention is applicable to the microelectronics field and especially to the manufacture of electrodes and the manufacture of photovoltaic panels.
