Title: METHOD FOR THE LOCALISED TRANSFER OF A PALLADIUM SPECIES ONTO A SUBSTRATE BY PAD PRINTING
Abstract:
A method for the localised transfer of a palladium species onto a substrate by pad printing, said method comprising the preparation (52) of an intermediate layer of molecules covering a contact face of a pad, said molecules each comprising a main chain, one end of said main chain ending in a less polar group and an opposite end of this main chain ending in a more polar group, the more polar group being chosen from the group consisting of thiols, amines, phosphines and disulphides, the less polar group having a polarity that is strictly lower than that of the more polar group, such that these molecules are only fixed to the contact face by means of Van Der Waals forces and such that the palladium species to be transferred bonds with the more polar group of the molecules, the main chain being a hydrocarbon chain comprising fewer than twenty carbon atoms.
