| 英文摘要 | in the current study, we investigate the self-assembly of polystyrene-block-poly(4-vinylpyridine) (ps-b-p4vp) confined in the nanopores of the anodic aluminum oxide (aao) template and the subsequent morphology transformation induced by the rayleigh instability. ps-b-p4vp nanotubes and nanorods with various internal nanostructures are fabricated by wetting the aao template with ps-b-p4vp/chloroform solution, and then followed by solvent evaporation. after the removal of aao template by potassium hydroxide solution, several different solvents (chloroform, toluene, and n,n-dimethylformamide) with different qualities are used to swell and anneal those nanotubes and nanorods suspended in aqueous media. morphology transformation from nanostructured ps-b-p4vp nanotubes or nanorods to ordered nanospheres is observed by annealing upon chloroform and toluene while the morphology remains unchanged upon n,n-dimethylformamide annealing, indicating that solvent quality is a key factor in tuning the morphology and internal structures. kinetics study and theoretical analysis for the morphology transition from two-dimensional (2d) block copolymer (bcp) nanotubes and nanorods to three-dimensional (3d) bcp nanospheres are further performed. from the morphological evolution and the quantitative calculation, it is confirmed that this transition is induced by the rayleigh instability. this study provides a simple but promising method, that is, solvent annealing method, for the fabrication of bcp nanospheres with ordered internal nanostructures, which may have great application in drug delivery and other nanotechnology. |
