| 中文摘要 | an erasure-reconstniction porous structure with reversible antireflection (ar) property at near-infrared region (nir) was prepared for the first time based on solvent-stimuli-responsive phase transformation of polystyrene-block-poly(4-vinypyridine) (ps-b-p4vp). the inhomogeneous porous structure with a dense skin and porous underneath, which was obtained by the nonsolvent-induced phase separation of ps-b-p4vp film from micelle solution with mixed solvents (tetrahydrofuran and dimethylformamide), was used as starting porous film. then, the film was annealed by ps-selective solvent to erase the nanopores because the ps block was swollen effectively by its selective solvent. afterward, the nonporous film was immersed in linear aliphatic acid to reconstruct the nanoporous structure (loosely packed micelles) by the combination of the hydrogen bond interaction and the positively charge-induced repulsion between each chain. thus, an intelligent reversible ar property in the nir region between a high-transmittance porous state (similar to 99.0%) and a low-transmittance nonporous state (similar to 90.0%) was realized by alternate treatments of ps-selective solvent and linear aliphatic acids. this reversible erasure-reconstruction porous structure for switching between ar (98.0%) and non-ar (90.0%) properties could be recycled by at least four times. |
