摘要： A segregated polymeric material is described that includes a silicon-based hydrophobic polymer and a copolymer comprising a silicon-based hydrophobic polymer and a hydrophilic segment, wherein the copolymer has been segregated to a surface of the material by contacting the surface with an aqueous solution. The segregated polymeric material can be used to improve the wettability and decrease the protein adsorption of a surface.

摘要： A two-layer photo-responsive membrane including a polymer layer and a support layer, the polymer layer being disposed on a surface of the support layer. The polymer layer is formed of a graft copolymer that contains a hydrophobic backbone and multiple side chains, the side chains each consisting of repeat units that switch between a hydrophobic form and a hydrophilic form upon exposure to a light of a specific wavelength. The polymer layer has a molecular weight cut-off of 3,000 to 250,000 Daltons and a thickness of 50 nm to 10 µm; and the support layer has a molecular weight cut-off of 50 to 250,000 Daltons. Also disclosed is a method of preparing this two-layer photo-responsive membrane.
