  • Patent number: 9708453
    Abstract: The method of the present disclosure is a method for producing a porous polymer film including: irradiating a strip-shaped polymer film with an ion beam while moving the polymer film transversely to the ion beam, so as to form a polymer film that has collided with ions in the beam; and chemically etching the formed polymer film so as to form openings and/or through holes corresponding to tracks left by the colliding ions in the polymer film. The ion beam (11) with which the polymer film is irradiated is obtained by folding a tail of an original beam (51) inwardly toward a center of the original beam by nonlinear focusing. The original beam is composed of ions accelerated in a cyclotron and has a cross-sectional intensity distribution profile in which an intensity is maximum at the center of the original beam and continuously decreases from the center toward the tail of the original beam, and the profile is an intensity distribution profile in a cross section perpendicular to a direction of the original beam.

  • Publication number: 20160304679
    Abstract: The method of the present disclosure includes: (I) irradiating a polymer film (1) with an ion beam composed of ions (2) accelerated in a cyclotron so as to form a polymer film that has collided with the ions in the beam; and (II) chemically etching the polymer film formed in the irradiation (I) so as to form openings (4b) and/or through holes (4a) corresponding to tracks (3) left by the colliding ions in the polymer film. In the irradiation (I), a beam current value of the ion beam is detected upstream and/or downstream of the polymer film in a path of the ion beam, and an irradiation conditioning factor in the irradiation of the polymer film with the ion beam is controlled based on the detected beam current value so that the polymer film can be irradiated with the ions at a predetermined irradiation density. The method of the present disclosure is suitable for industrial production of porous polymer films.

  • Patent number: 8372558
    Abstract: A vinyl monomer is graft polymerized on an aromatic hydrocarbon-based polymer film substrate to introduce graft chains into the substrate and thereafter a functional monomer represented by the following formula and having sulfonic acid groups or functional groups capable of conversion to sulfonic acid groups is graft polymerized to introduce the sulfonic acid groups or the functional groups capable of conversion to sulfonic acid groups: where R is an aromatic ring or an aliphatic chain; X is (1) —OH, (2) —OLi, —ONa or —OK, (3) —F or —Cl, or (4) —OCnH2n+1 where n is an integer of 1 to 7. Since the graft chains obtained by graft polymerization of the vinyl monomer can also be utilized as scaffold polymers, the graft polymerizability of the functional monomer to the aromatic hydrocarbon-based polymer film substrate is sufficiently improved to enable the preparation of a polymer electrolyte membrane that excels not only in proton conductivity and mechanical strength but also in dimensional stability.
