W-doped VO2/PVP coatings with enhanced thermochromic performance

The preparation of VO2-based polymer coatings with simultaneously high visible transmittance and high solar modulation ability has been elusive for smart window design. In this work, reflux synthesis was examined with ammonium metavanadate as a non-toxic precursor, being reduced by aspartic acid in a water-based approach for the synthesis of monoclinic vanadium dioxide [VO2(M)]. The optimum synthesis conditions were determined for an oxidation...
