Photoreversibly Switchable Superhydrophobic Surface with Erasable and Rewritable Pattern
TL;DR: The facile fabrication of a functional nanoporous multilayer film with wettability that is reversibly tunable between superhydrophobicity and superHydrophilicity with UV/visible irradiation is reported, opening up new avenues for external stimuli-responsive smart surfaces.
Journal ArticleDOI
UV-Driven Reversible Switching of a Roselike Vanadium Oxide Film between Superhydrophobicity and Superhydrophilicity
TL;DR: The fabrication of a roselike nanostructured vanadium oxide (V2O5) film with photoinduced surface wettability switching by carrying out the drop-casting of a suspension of V2 O5 particles synthesized with the sol−gel method provides not only the possibility of producing large homogeneous or patterned surfaces with tunable wettabilities, but also potential uses in catalysts, catalysts and coatings.
Journal ArticleDOI
Solubility-Induced Ordered Polythiophene Precursors for High-Performance Organic Thin-Film Transistors
Yeong Don Park,Hwa Sung Lee,Yeon Joo Choi,Donghoon Kwak,Jeong Ho Cho,Jeong Ho Cho,Sichoon Lee,Kilwon Cho +7 more
TL;DR: In this article, the authors improved the field effect mobility of self-assembled regioregular poly(3-hexylthiophene), P3HT, by adding small amounts of the non-solvent acetonitrile to the solutions prior to film formation.
