Abstract
For surface modification of natural or synthetic macromolecular substrates, organic compounds are used that have hydrophilic, hydrophobic, oleophobic, ionic and/or cross-linkable groups and that also have groups which are easily convertible to nitrene or carbene, e.g., azide or diazo groups. Such organic compounds are applied to the surface to be modified as a monolayer or oligolayer from a solution thereof and then are photochemically activated. Conditions which cause orientation of the molecule with the azide or diazo group toward the surface of the substrate are advantageous. The other cross-linkable groups may promote diagonal cross-linking of the applied layer.
Claims11
Process for covalent surface modification of a macromolecular substance comprising applying a solution of an organic monomeric compound having a hydrophobic linear chain having 1 to 26 carbon atoms, having at least one azide or diazo group at one end of said monomeric compound, and having at least one hydrophilic, hydrophobic, oleophobic and/or ionic group present at the opposite end of said monomeric compound, to the surface of said macromolecular substance and then photochemically activating said organic monomeric compound to convert said at least one azide or diazo group of said organic monomeric compound into at least one nitrene or carbene group, respectively.
