Abstract:
Rigid polystyrene foams contain thermally treated non-graphitic anthracite coke particles. Such athermanous materials permit a more energy-efficient grinding process, wherein the ground particles are yielded in the desired platelet form and these ground particles also disperse well in a polystyrene matrix. Therefore the rigid polystyrene foams containing the anthracite coke particles have a density of less than 40 kg/m3 and a thermal conductivity of less than 40 mW/m·K which provides desired thermal insulation properties.

Abstract:
The present invention relates to a heat-ray-shielding sheet that includes, on a support, a heat-ray-shielding layer including heat-shielding microparticles and a resin binder filling a void part. The microparticles are made of tin-doped indium oxide (ITO) or the like and have an average particle diameter of equal to or less than 100 nm, the reflectance in the heat-ray-shielding layer at a wavelength of at least 2,000 nm is at least 15%, and the surface resistivity in the heat-ray-shielding layer is equal to or more than 106Ω/□. Increasing the surface resistivity imparts a radio-wave-transmitting property, and causing longer-wavelength near-infrared light to be reflected boosts heat-ray-shielding efficiency while preventing thermal cracking and the like of a glass substrate. Additionally compounding the heat-ray-shielding layer with a near-infrared-absorbing dye, or disposing a reflecting layer in addition to the heat-ray-shielding layer allows the heat-ray shielding effect to be further improved.

Abstract:
Disclosed is a method for producing edge-functionalized graphite with phosphoric acid. According to the method, graphite is pulverized into smaller pieces and is then exposed to an atmosphere containing oxygen and water. The method enables the production of graphite functionalized with phosphoric acid groups, which could not be achieved by conventional mechanochemical methods. In addition, the method is carried out in a very simple and economical manner and is suitable for large-scale production.
