Controlled microphase separated morphology of block polymer thin film and an approach to prepare inorganic nanoparticles

Well-defined amphiphilic block copolymers polystyrene-b-poly(ethylene oxide)-b-polystyrene (PS-b-PEO-b-PS) and polystyrene-b-polyethylene oxide (PS-b-PEO) with controlled block length were synthesized using atomic-transfer radical polymerization (ATRP). The films fabricated by drop coating the block...

More Information
Summary:Well-defined amphiphilic block copolymers polystyrene-b-poly(ethylene oxide)-b-polystyrene (PS-b-PEO-b-PS) and polystyrene-b-polyethylene oxide (PS-b-PEO) with controlled block length were synthesized using atomic-transfer radical polymerization (ATRP). The films fabricated by drop coating the block copolymer solution on mica show the marked microphase separated morphologies, which strongly depend on the block length ratio. The furrow maps of these films predict that they can be used as templates to prepare inorganic nanoparticles.
