Abstract:
A coating film to prevent a conspicuous fingerprint has a water contact angle of no less than 60° so that most of water contained in fingerprints on the coating film evaporates without forming a layer adsorbed on the coating film. Further, the coating film has lipophilicity and has a diiodomethane contact angle of no more than 45° so that the coating film exhibits enhanced affinity to fingerprints, which primarily contain oily components.
Abstract:
A polymer electrolyte composition for a dye-sensitized solar cell, a polymer electrolyte, a dye-sensitized solar cell employing the polymer electrolyte, and a method for preparing the same. The polymer electrolyte composition for a dye-sensitized solar cell includes: a mono-functional or multi-functional monomer having at least one ethylene glycol in a side chain; a photoinitiator; a lithium salt; and an organic solvent. The polymer electrolyte suppresses the volatilization of a redox electrolyte and provides stable photoelectrochemical properties against environmental changes, such as a rise in the external temperature of a solar cell. The dye-sensitized solar cell includes: first and second electrodes facing each other; a dye-adsorbed porous film interposed between the first and second electrodes; and the polymer electrolyte interposed between the first and second electrodes. The dye-sensitized solar cell has a high voltage and high photoelectric conversion efficiency.

Abstract:
A fusing unit which includes a pressure member to be elastically supported on an outer peripheral surface of a heating roller while coming into surface contact with the outer peripheral surface. The pressure member serves to grind the outer peripheral surface of the heating roller, to maintain a surface roughness of the heating roller at a predetermined level or less.
