Publication number: 20150228994Abstract: Provided is a polymer electrolyte membrane that is formed of a fluorine free material, is soft and hardly cracks, and is excellent in hot water resistance. The polymer electrolyte membrane is obtained by crosslinking a block copolymer (Z) containing a polymer block (A) containing a structural unit derived from an aromatic vinyl compound and having an ion-conducting group; and an amorphous polymer block (B) containing a structural unit derived from an unsaturated aliphatic hydrocarbon and free of any ion-conducting group, the block copolymer (Z) being crosslinked with a crosslinking agent (X) having, in a molecule thereof, two or more aromatic rings of which one or more hydrogen atoms are substituted with hydroxy groups.Type: ApplicationFiled: August 12, 2013Publication date: August 13, 2015Applicant: KURARAY CO., LTD.Inventors: Kenta Toshinari, Sayaka Ede, Taketomo Yamashita, Tomohiro Ono, Nozomu Sugoh

Patent number: 8993192Abstract: An electrolyte membrane having a structure wherein fine rubber particles having substantially no ion-conducting group and having an average particle size of 20 nm to 1 ?m are uniformly dispersed in a matrix including a resin component having ion-conducting group. The electrolyte membrane has high bonding ability to electrodes and does not cause cracks and ruptures because it is kept flexible even under low humid or absolutely dried condition, in addition, shows high ion conductivity even under low humid or absolutely dried condition because the matrix having ion-conducting groups are continuous.Type: GrantFiled: February 12, 2010Date of Patent: March 31, 2015Assignee: Kuraray Co., Ltd.Inventors: Tomohiro Ono, Takeshi Nakano, Taketomo Yamashita, Keiji Kubo, Nozomu Sugoh

Publication number: 20120007277Abstract: Methods and devices for forming a vertically-oriented multilayer laminates, for example, a vertically-oriented multilayer laminates, are provided. The laminates may be fabricated by hardenable fluids, for example, polymers that are directed along flow paths to divide, repossession, and combine streams to provide the desired laminated structure. The flow divisions and recombination may be practiced repeatedly wherein laminates have tens or even tens of thousands of individual layers may be produced. The polymers used may have comparable viscosities, for example, having viscosity ratios of less than 3. Though aspects of the invention may be used packaging, aspects of the invention may be applied to any field where laminated structures are desired.Type: ApplicationFiled: August 5, 2009Publication date: January 12, 2012Applicants: KURARAY CO., LTD., UNIVERSITY OF MASSACHUSETTS LOWELLInventors: Eiji Nakamura, Nozomu Sugoh, Tomiaki Otake, Joey Mead, Stephen Orroth, Carol Barry, Mithun Kamath, Scott Winroth
