文摘
The potential electrochromic application of graphene-based nanohybrids is hampered by the challenges in interfacing the electrochromic nanoparticles with graphene at atomic scale and in fabricating their thin film on the substrate through a scalable method. In an effort to overcome these challenges, we demonstrate a highly dispersible graphene-based molybdenum oxide nanohybrid (mRGO-MoO3–x) for flexible electrochromic application. With only a squeeze pipet, mRGO-MoO3–x could be deposited with a high coverage on various substrates through a scalable equipment-free Langmuir–Blodgett film deposition method. By taking advantage of high transmittance benefited from its remarkable thinness, the mRGO-MoO3–x Langmuir–Blodgett film shows a superior reversible electrochromic property with high coloration efficiency on both hard and flexible substrates.
