  • Patent number: 11306190
    Abstract: A method for modifying a polymeric surface is disclosed. The polymeric surface is activated utilizing atmospheric pressure plasma. An atom transfer radical polymerization initiator is then coupled to the activated surface. A monomer is then polymerized on the activated surface utilizing an activators regenerated by electron transfer (ARGET) atom transfer radical polymerization (ATRP) process. The method enables brush-modification of the polymeric surface, even if the polymeric surface is substantially chemically inert. By way of example, the method enables a chemically inert, substantially hydrophobic polymer surface to be functionalized with substantially hydrophilic polymer brushes. The methods of the present disclosure have general applicability to a myriad of implementations where tunable surface chemistry is advantageous, such as filtration membranes, marine surfaces, and medical devices seeking a biocompatible coating.
