Conductive photoswitchable vanadium oxide nanopaper based on bacterial cellulose
Résumé
A bacterial cellulose mat was used as a template for the fabrication of conductive photoswitchable hybrid nanopaper by the incorporation of sol-gel synthesized vanadium nanoparticles. The resulting nanopaper, prepared through a green pathway, was able to photoinduce a reversible color change. Conductive properties at the nano- and macroscales were confirmed by electrostatic force microscopy and semiconductor analysis measurements, respectively. Flexible, conductive nanopaper: A bacterial cellulose mat is used as template for the fabrication of a conductive photoswitchable hybrid nanopaper by the incorporation of sol-gel synthesized vanadium nanoparticles. A simple, rapid, and low-cost pathway is developed for the production of vanadium oxide nanopaper. This work enables a new strategy for the fabrication of flexible, conductive, and optically active photochromic nanopaper. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
