| Abstract Scope |
Various types of nanobrush (e.g., vertically-oriented polymer grafts and carbon nanotubes) draw a considerable attention as a new class of functional materials with shape-derived unique properties. In this paper, we report the synthesis of titanate nanofunnel brushes by hydrothermal treatment of sol-gel derived amorphous TiO2 thin films. This specific nanostructure has not been reported so far; the top of nanosheets is a completely rolled tubular shape and the bottom end of wide skirt side is anchored on the substrate. Also, the surface morphology can be tuned from nanosheets to nanofunnels by changing NaOH concentration during hydrothermal treatment. The unique morphology enables us to control its surface chemistry for the fabrication of functional interfaces. As an example of such an interfacial application, a superhydrophobic adhesive surface for small water droplet delivery was demonstrated. |
