METHOD FOR PREPARING V2O5 NANOWIRE FILM HAVING IMPROVED ALIGNMENT AND THE V2O5 NANOWIRE FILM PREPARED THEREFROM

摘要

A method for manufacturing a divanadium pentaoxide nano wire thin film with improved alignment is provided to conveniently cut manufactured nano wires in order to secure reproducibility and characteristic of devices. A method for manufacturing a divanadium pentaoxide nano wire thin film comprises the following steps of: preparing a divanadium pentaoxide nano wire(V2O5 nano-wire) solution; diluting the solution in water and inputting the diluted solution into the Langmuir-Blodgett trough; adding a dispersing agent to the diluted solution; diluting a halogenated dioctadecyl dimethylammonium solution in an organic solvent and coating the diluted halogenated dioctadecyl dimethylammonium solution on the surface of the diluted solution prepared in previous step; adjusting the interface pressure of the halogenated dioctadecyl dimethylammonium solution by using a barrier in the Langmuir-Blodgett trough; fixing a substrate on a dipping rod of the Langmuir-Blodgett trough and contacting the substrate with the interface of the halogenated dioctadecyl dimethylammonium solution; and separating the substrate from the dipping rod.
