PROCESS FOR MASK-FREE LOCALIZED ORGANIC GRAFTING ONTO CONDUCTIVE OR SEMICONDUCTIVE PORTIONS OF COMPOSITE SURFACES

摘要

The invention concerns a mask-free localised grafting of organic molecules capable of being electrically activated, on a composite surface comprising conductive and/or semiconductive portions, by contacting said organic molecules with said composite surface, whereby the grafting is carried out electrochemically in one single step on specific selected zones of said conductive and/or semiconductive portions, said zones being brought to a potential not less than an electric potential threshold determined relative to a reference electrode, said electric potential threshold being the potential beyond which the grafting of said organic molecules occurs.
