  • Patent number: 11383008
    Abstract: The present invention relates to an efficient method for grafting a properties-imparting compound onto a polymeric substrate containing carbon-hydrogen (C—H) bonds using clip chemistry. The method of the invention includes coating the substrate with the properties-imparting compound and irradiating it with a reactive light source, and repeating this sequence at least once. The present invention further relates to surface-modified polymeric substrates grafted with a properties-imparting compound, in particular obtained with the method of the invention, medical devices comprising same, and non-medical of said surface-modified polymeric substrates.
