| 中文摘要 | Poly(acrylic acid)-block-polystyrene (PAA-b-PS) functionalized multiwall carbon nanotubes (MWNTs)were prepared by nitroxide-mediated ‘‘living” free-radical polymerization. The product functionalizedMWNTs (MWNT-PAA-b-PS) contained 20% by weight PAA-b-PS based on the infrared spectroscopy anal-ysis and thermal gravimetric analysis. Such MWNT-PAA-b-PS nanoparticles can be used in spray coatingmethod to fabricate superhydrophobic MWNT films, and water-droplet mobility on the superhydropho-bic film can be reversibly converted from rollable to pinned through adjusting the appearance of PAAchains on the topmost surface of the film. Switching mechanism has been discussed in detail. We alsodirectly observed the air–solid–liquid interface from the above of a water droplet by a microscope to con-firm the superhydrophobic states, and proved that the transition between the wettability states appearedon the same surface with reversible conversion of water-droplet mobility. |
