Abstract:
1. A method for producing a film of vanadium pentoxide nanowires with improved alignment, the method comprising the steps of a) preparing a solution of vanadium pentoxide (V b) diluting the solution of vanadium pentoxide nanowires with water and feeding the dilute aqueous solution into a Langmuir-Blodgett trough, c) adding a dispersant to the dilute aqueous solution of vanadium pentoxide nanowires, d) diluting a solution of a dioctadecyldimethylammonium halide with an organic solvent, applying the dioctadecyldimethylammonium halide solution to the surface of the dilute aqueous solution of vanadium pentoxide nanowires in the Langmuir-Blodgett trough, and allowing the solutions to stand to disperse the dioctadecyldimethylammonium halide solution in the Langmuir-Blodgett trough, e) controlling the surface pressure of the dioctadecyldimethylammonium halide solution using barriers mounted on the Langmuir-Blodgett trough, f) affixing a substrate to a dipping arm of the Langmuir-Blodgett trough and bringing the substrate into contact with the surface of the dioctadecyldimethylammonium halide solution, and g) separating the substrate from the dipping arm.
