Self-Disinfecting Frequently Touched Surface

A frequently-touched surface for use by multiple users includes a surface protected by a laminate structure. The laminate structure includes a self-sterilizing sulfonated polymeric outer layer, sulfonated to a certain % to kill at least 95% microbes within 30 minutes of contact. The self-sterilizing sulfonated polymer layer can be applied to the frequently touched surface by any of coating, lamination, and spraying. The sulfonated polymer in embodiment is selected from perfluorosulfonic acid polymers, polystyrene sulfonates, sulfonated block copolymers, sulfonated polyolefins, sulfonated polyimides, sulfonated polyamides, sulfonated polyesters, sulfonated polysulfones, sulfonated polyketones, sulfonated poly(arylene ether), and mixtures thereof. The sulfonated polymer has a degree of sulfonation of at least 10%.

VERTICALLY PHASE-SEPARATED LAYER OF A BLOCK COPOLYMER

A layer including a block copolymer in which a microphase-separated structure of the block copolymer has been induced perpendicular to a substrate, this process being difficult in heating under atmospheric pressure; a method for producing the layer; and a method for producing a semiconductor device in which is used a vertically phase-separated layer of a block copolymer. A vertically phase-separated layer of a block copolymer formed by heating at a pressure below atmospheric pressure and a temperature at which induced self-assembly can occur.
