Abstract:
An epoxy resin - barium titanate composite is provided to suppress the percolation due to the contact between batio3 molecules by mixing ceramic particle surface-treated with an organic dispersing agent and a polymer resin. An epoxy resin - barium titanate composite comprises barium titanate surface-treated with an organic dispersing agent. The organic dispersing agent is selected from the group consisting of polystyrene having a maleic anhydride or acrylic acid at the end, a block type copolymer of maleic anhydride or acrylic acid and polystyrene, and sulfonated polystyrene at a main chain.
Abstract:
PURPOSE: A dispersion-controlled carbon nano-tube electrode and a counter electrode for a dye-sensitized solar cell using the same are provided to improve the dispersing property of the carbon nano-tube by wrapping the carbon nano tube. CONSTITUTION: A conductive transparent electrode(102) is formed on the upper transparent substrate(101). An oxide semiconductor layer(103) is formed on the conductive transparent electrode. Photosensitive dye is absorbed to the surface of the oxide semiconductor layer. A thin or thick counter electrode(105) is formed on the lower substrate(106). Electrolyte(104) is filled in the counter electrode.
Abstract:
PURPOSE: Provided is a process for preparing a cellulose fiber structure by impregnating a cellulose fiber structure with an aqueous solution of a phosphorous compound and a nitrogen compound, heat treating in a nitrogen atmosphere, converting the obtained cellulose ammonium phosphate ester compound to a cellulose sodium phosphate ester compound by ion exchange and coupling a refractory metal is provided. Thereby the obtained fiber structure can be used for fire retardant material, insulating material and high temperature filter material. CONSTITUTION: This process comprises the steps of: forming a cellulose ammonium phosphate ester compound by impregnating a cellulose fiber structure containing cellulose fiber with an aqueous solution of a phosphorous compound and a nitrogen compound and reacting at 200 to 400deg.C in a nitrogen atmosphere; forming a cellulose sodium phosphate ester compound by ion exchange of the formed compound in a sodium hydroxide solution; coupling with a metal ion by impregnating the formed cellulose sodium phosphate ester compound with an alcohol solution of refractory metal chloride.
