Summary: WO3 nanoparticles and MoO3 nanoribbons were prepared using a microwave-assisted hydrothermal method. A stable WO3/MoO3 suspension with a nanoheterojunction structure was obtained after grinding treatment. The ground WO3/MoOx composite film exhibited enhanced electrochromic performance due to its morphology and enhanced electron transfer. A complementary electrochromic device (ECD) using ground WO3/MoOx showed high transmittance modulation, fast switching times, high coloration efficiency, and cycling stability.

Summary: The high-performance electrochromic polyamide NPTB-PA shows multi-oxidation stages and lower oxidation potentials due to the strong electron-donating ability of dimethylamino groups. By forming covalent bonds between polymer backbones and precursor of zirconium dioxide via in-situ sol-gel reaction, the hybrid films could shorten the switching response time and reduce oxidation redox potentials. In the ECD, the combination of NPTB-PA and HV exhibits panchromatic absorption and extremely high contrast of transmittance change.
