CONTROLLED ARCHITECTURE MATERIALS

摘要

A block copolymer; a method of reducing the surface tension of a liquid comprising adding to said liquid less than 10 wt % of a surface active agent derived from the block copolymer; a method for modifying the surface chemistry of a polymeric substrate comprising adding less than 10 wt % of a surface active agent derived from the block copolymer; a polymerized foam composition made from a mixture containing one or more of monomers, oligomers, and polymers, the mixture comprising less than 10 wt % of a surface active agent derived from the block copolymer and an article comprising the polymerized foam. A block copolymer comprising at least one block having a quaternary ammonium ion.
