Multicolor electrochromic film based on SnO2/V2O5 core/shell structure for adaptive camouflage

Abstract

Electrochromic films with high stability and large color contrast have application prospects in advanced adaptive camouflage. In this work, a SnO2/V2O5 core/shell composite film with rough surface is prepared by combining hydrothermal and electrodeposition methods. The composite film exhibits remarkable electrochromic properties, including large transmittance modulation (47%), high coloration efficiency (118 cm2 C1) and admirable optical cyclic stability. The core/shell structure plays a pivotal role in the enhanced electrochromic performances due to the large reactive area and high adhesion to substrate. Impressively, highly reversible color change among yellow, green, and blue is observed in the electrochromic film, suggesting its potential application in adaptive camouflage for conditions of desert, oasis and ocean.
