摘要: Patterning silicon surfaces by well-ordered nanoperforated TiO(2) layers is achieved through a simple block copolymer-assisted liquid deposition technique followed direct thermal treatment. The crater diameters are tuned between 10 and 50 nm, depending on the molecular weight of surfactant patterning agent. formation mechanism such systems discussed. present nanopatterned heterogeneous (nanoholes with SiO(2) bottom walls) selectively functionalized two different perfluorinated organic groups. accessibility to substrate surface nanoholes selective distribution both functions evidenced water-contact-angle measurements, which satisfactorily verify Cassie relationship. Such have wide application prospects in varied fields as nanotechnology engineering.
