中文摘要a new method of reversibly moving us nanoparticles in the perpendicular direction was developed on the basis of the phase separation of block copolymer brushes. polystyrene-b-(poly(methyl methaerylate)-co-poly(cadmium dimethacrylate)) (ps-b-(pmma-co-pcdma)) brushes were grafted from the silicon wafer by surface-initiated atom transfer radical polymerization (atrp). by exposing the polymer brushes to h2s gas, ps-b-(pmnla-co-pcdnla) brushes were converted to polystyrene-b-(poly(methyl methacrylate) -co-poly(methacrylic acid)(cds)) (ps-b-(pmma-co-pmaa(cds))) brushes, in which us nanoparticles were chemically bonded by the carboxylic groups of pmaa segment. alternating treatment of the ps-b-(pmma-co-pmaa(cds)) brushes by selective solvents for the outer block (a mixed solvent of acetone and ethanol) and the inner ps block (toluene) induced perpendicular phase separation of polymer brushes, which resulted in the reversible lifting and lowering of us nanoparticles in the perpendicular direction. the extent of movement can be adjusted by the relative thickness of two blocks of the polymer brushes.
