    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.

    摘要: The invention relates to composite materials, more specifically to composite membrane materials on the basis of polymeric materials used for the purification of a liquid, in particular drinking water. The novel composite material for the purification of a liquid by filtration is formed from a polymeric membrane in the form of a fibrillar-porous matrix comprising a hydrophilic polymer and a metallic antibacterial agent. The fibrillar-porous matrix comprises, at least in part of the volume thereof, stable active zones consisting of clusters of a metallic antibacterial agent in combination with molecules of hydrophilic polymer, wherein at least some of the clusters of metallic antibacterial agent are bonded to one another and to the surface of the pores of the matrix by means of the molecules of hydrophilic polymer, wherein at least some of the clusters of metallic antibacterial agent are additionally chemically bonded to the surface of the pores of the matrix, wherein the mean distance between the active zones is smaller than at least three times the mean diameter of the pores of the matrix. The technical result achieved using the invention consists in achieving stable hydrophilicity of the polymeric membrane during use thereof while at the same time maintaining the permeability of the polymeric membrane and increasing the bacteriostasis of the composite material. An additional technical result achieved using the invention consists in increasing the bacteriostasis of the juxtamembrane region during filtration of a liquid.
