“…This technique has been applied in various fields as a simple method to fabricate metal oxide thin films. Silica-like polymers (polysilsesquioxane), in which one of the substituents on the silicon atom is replaced by an organic group, can also be synthesized by the same method, and various functions can be introduced by the organic substituents [40][41][42][43][44][45][46][47].…”

Since graphene oxide can be synthesized in large quantities by oxidation of inexpensively available natural graphite and can be dispersed in water, it can be coated onto a variety of substrates by solution processes. Graphene oxide can also be reduced to yield reduced graphene oxide, which has similar electronic features to graphene. This review introduces the environmentally friendly methods for the synthesis of reduced graphene oxide utilizing electrochemical and thermal methods and summarizes our recent research results on their application to energy-related materials such as electric double-layer capacitors, thermoelectric devices, transparent conductive films, and lithium-ion secondary batteries.

Since GO is obtained by oxidizing graphite under acidic conditions and exfoliating it in water and the product contains many acidic functional groups such as hydroxyl and carboxyl groups, the aqueous dispersion of GO can be obtained in an acidic state.…”

We developed new oxidative electrochromic materials based on triarylamines and benzidine. These were coated onto substrates and cured by UV irradiation to obtain polymer films. These materials emitted yellow, magenta and cyan colored light. In color devices using these materials, high transmittances of the uncolored states and high optical densities of the colored states were shown to be compatible. We demonstrated that CMYK and RGB can be expressed by mixing these materials. We also succeeded in prototyping EC decorative glass by combining these materials and using inkjet printing; this represents a new application for oxidative EC materials.
