    Abstract: Purposes of the present invention are to provide a carbon-fiber-containing concrete or mortar composition which has excellent handleability due to a reinforcement produced from precut raw-material carbon fibers, such as short fibers, scrap fibers resulting from processes, or carbon fibers reclaimed from CFRPs, etc., and to provide a carbon-fiber-reinforced concrete or mortar structure which is a cured object formed from the carbon-fiber-containing concrete or mortar composition and in which the fibers have a high reinforcing effect. This carbon-fiber-containing concrete or mortar composition includes carbon-fiber masses each configured at least from carbon fibers and a binder, and is characterized in that the carbon-fiber masses each have the shape of a spindle.

    Abstract: Provided is a binder for use in an electrode layer or separator for a lithium-ion secondary battery, wherein the binder is unlikely to cause powder removal and does not completely cover the surface of the active material particles when used in an electrode layer as a binder. The binder of the present invention is a binder for a non-aqueous secondary battery, the binder comprising a fibrid of an aromatic polyamide, wherein the fibrid swells and is not dissolved in an N-methyl-2-pyrrolidone solvent in which an alkali metal salt and/or an alkaline earth metal salt is present at a concentration of 1,000 ppm or less, and is completely dissolved in an N-methyl-2-pyrrolidone solvent in which an alkali metal salt and/or an alkaline earth metal salt is present at a concentration of 10,000 ppm or more.

    Abstract: Provided is a conductive film for antennas, in which a conducting film and a substrate made of a polycarbonate resin material containing a polycarbonate resin are laminated, and the polycarbonate resin contains, as main constituent units, a unit (A) represented by the following formula (1) and/or a unit (B) represented by the following formula (2). The conductive film for antennas has low dielectric characteristics and bendability, can form an antenna with a low transmission loss, and has excellent adhesion to the conducting film.




    (In the formula (1), R1 and R2 each independently represent an alkyl group having 1 to 6 carbon atoms or a halogen atom, and R3 and R4 each independently represent a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, or a halogen atom.)





    (In the formula (2), R1 and R2 each independently represent an alkyl group having 1 to 6 carbon atoms or a halogen atom, R3 and R4 each independently represent a hydrogen atom, an alkyl group having 1 to 6 carbon atoms, or a halogen atom, R5 represents a halogen atom, an alkyl group having 1 to 20 carbon atoms, or a cycloalkyl group having 3 to 20 carbon atoms, and n represents an integer of 0 to 10.)
