## Description

- description: In this study, we developed binder-enhanced reversible photochromic
    tungsten oxide (WO3) films for advanced applications. Expanding on previous research,
    we used tungsten oxide hybrid composites as the base material and incorporated
    various binders, specifically polyethylene glycol (PEG), polysorbate 80 (PS 80),
    and carboxymethyl cellulose (CMC), to evaluate their effects on reversible photochromic
    reactions. Our experiments demonstrated that the inclusion of CMC significantly
    improved the photochromic properties and exhibited the fastest reversible reactions
    when compared to PEG and polysorbate 80. This enhancement is attributed to the
    high density of hydroxyl groups and the network structure of CMC, which facilitate
    efficient proton transfer and oxygen permeability, both crucial for the reoxidation
    process in WO3. Density functional theory (DFT) calculations supported these findings
    by indicating that CMC has a suitable bandgap and electron mobility, which enhance
    charge injection and transport. Additionally, the fabricated films showed consistent
    and stable performance under both heat treatment and natural ambient conditions.
    These results underscore the potential of CMC as an effective binder for developing
    high-performance, reversible photochromic films suitable for applications in smart
    windows, displays, and optoelectronic devices.
