Popis: | Metallic substrates are modified by a polymeric layer obtained under photochemical irradiation of acetonitrile. The reaction involves a photogenerated radical and leads to the covalent bonding of the organic layer to the metal. Different characterization techniques allow to unravel the structure of the layer: Substrate-CH2-CH-(NH2)[-CH2-CH-(NH2)-]n-[CH2-C(═O)]m. A mechanism is discussed that accounts for the formation of the layer. The method is quite easy to implement, it only necessitates a UV lamp and a very common solvent. Photografting is well suited to pattern surfaces with polymeric layers by irradiation through a mask, and finally, the patterning of copper at the micrometer scale is described as a proof of concept. |
