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 关键词: liquid phase deposition;nanoparticles;nanotechnology;polymer blends;polymer films;polymer structure;polymerisation;surface morphology;microphase morphology;amphipilic block polymer thin film;inorganic nanoparticles;atomic transfer radical polymerization;drop coating;block copolymer solution;mica;block length ratio;polystyrene-b-poly (ethylene oxide)-b-polystyrene;polystyrene-b-polyethylene oxide;surface morphology;Al2O3-K2O-SiO2
