Thin films of electrochromic (EC) materials are being used as energy saving platforms. However, manufacturing high quality of such films while ensuring their superior stability and high coloration availability, as well as their persistency in diverse conditions of temperature and/or illumination, is challenging. Herein we proposed to create the next generation of composites that display EC characteristics using a user-controlled manufacturing strategy based on Matrix Assisted Pulsed Laser Evaporation (MAPLE). In our approach, tungsten trioxide and graphene oxide were employed as starting materials, with MAPLE controlling material deposition conditions and overall composites' thickness. The resulting EC composites were characterized for their chemical and physical properties using Fourier Transform Infrared Spectroscopy and Energy Dispersive Spectroscopy, and Optical and Atomic Force Microscopy respectively, with changes in their electrochemical characteristics being evaluated by cyclic voltammetry and related to film thickness through the use of spectrophotometry. It was found that MAPLE deposition conditions allow for formation of composites that display enhanced electron transport capabilities and high energy efficiency at their interfaces; further, it was found that MAPLE allowed for uniform films production, of controlled thickness as well as eliminated possible impurities normally associated with other methods used for EC films production such as sputtering, sol-gel or electrodeposition, and chemical wet deposition respectively. Our work could potentially provide a user-controlled synthesis and manufacturing strategy for the formation of next generation of EC thin films that have minimum interfacial defects while possessing maximum conversion efficiency to thus influence and/or dictate their energy saving profiles.
