  • Patent number: 11884579
    Abstract: A process for the modification of a surface of a solid material, having the step of contacting the surface with a surface-modifying composition under irradiation with light of a wavelength in the range of 200 to 800 nm optionally in the presence of a photoinitiator, wherein the solid material has surface groups selected from C—OH, Si—OH, C?O and C—O—C groups and wherein the surface-modifying composition has at least a hydrosilane and at least one reactive compound (A) other than the hydrosilane, wherein the reactive compound (A) has at least two functional groups selected from (meth)acrylate, (meth)acrylamide, hydroxyl, carboxylic acid, alkene, alkyne and epoxy, and wherein the amount of hydrosilane in the composition ranges between 0.5 and 99 vol %, and wherein the vol % is determined at 20° C. relative to the total of the surface modifying composition. A solid material having a partial surface modification layer.

  • Publication number: 20200023333
    Abstract: A process for the modification of a surface of a solid material, said solid material comprising a polymer material arranged at the surface of the solid material. Said process comprises the step of: contacting the polymer at the surface of the solid material with an oxygen source and a catalytic amount of a transition metal compound under such conditions that oxygen is incorporated into the polymer surface, wherein a hydroxy group is formed, which is attached to a carbon atom of the polymer.
