成果简介：Fluoroalkyl silane (FAS)-loaded polystyrene microcapsules were prepared via Pickering emulsion polymerization using silica/titania nanoparticles as Pickering agents, wherein the nanoparticles were first modified with a Trixton X-100-tethered silane coupling agent. The microcapsules display rugged surfaces and have average sizes from 150 nm to 890 nm, depending on the nanoparticles-to-oil mass ratio. Under UV exposure, the microcapsules break up and release the encapsulated FAS, demonstrating their UV-responsive ability. The microcapsules were further embedded into waterborne coatings. Monitoring the evolution of the surface wettability of the coatings under UV-exposure indicates that the releasing rate of FAS could be tunable by the content of TiO2 nanoparticles in the microcapsules.
