Block copolymers with well-defined nanoscopic structures have recently gained much attention for their potential uses as functional nanostructures. I address on some applications of the block copolymer thin films: nanotemplates for PN heterojunction photovoltaic devices and separation membranes for biomaterials. To achieve this objective, cylindrical nanodomains in block copolymer are first perpendicularly oriented to a substrate. Then, cylindrical nanodomains with diameter of 10~40 nm are removed by either selective solvent etching or UV treatment; thus nanoporous templates are prepared. By using electropolymerization, high density nanowire arrays of conducting polymer of poly(pyrrole) and poly(3,4-ethylenedioxythiopene) were obtained and their electric properties were measured. Also, these nanoporous thin films were found to be very useful for the separation of human Rhinovirus type 14, major pathogen of a common cold in humans, from the buffer solution. |
