Abstract

The self-assembly of a silica-surfactant nanocomposite in a porous alumina membrane is discussed. A mesoporous membrane composed of nanochannels with a uniform diameter has a potential use for precise size-exclusive separation of molecules. A novel method to form a hybrid membrane composed of silica-surfactant nanocomposite and a porous alumina membrane, by which size-selective transport of molecules across the membrane becomes possible is presented. The nanocomposite formed inside each columnar alumina pore is an assembly of surfactant-templated silica-nanochannels with a channel diameter of 3.4 nm.
