Though imidazolium groups were desired to connect with styrene groups via two different ways, i.e. parallel or perpendicular orientations to the graft-polymer chains via copolymerization (AEM1) or homo-polymerization (AEM2), both AEMs possess high ion conductivity (>100 mS/cm at 60 °C) and modest stability. The morphologies of these membranes were elucidated by small-angle neutron scattering method. Our results revealed that 1) both AEMs show clear microphase separation with a length scale of 30–40 nm, and the semi-crystalline structural feature of the hydrophobic microdomains contributes to the membrane mechanical property; 2) at the length scale <6 nm, ionic structures of the two AEMs are different: Parallel type of AEM1 shows a homogeneous distribution of ions in the ion channel; while perpendicular type of AEM2 shows ionic clusters nanophase-separated from the graft polymers.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.physb.2018.01.064","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://www.sciencedirect.com/science/article/pii/S0921452618300942?via%3Dihub#!"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.sciencedirect.com/science/article/pii/S0921452618300942?via%3Dihub#!","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0921-4526","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"ザオ, ユエ"}],"nameIdentifiers":[{"nameIdentifier":"500167","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"吉村, 公男"}],"nameIdentifiers":[{"nameIdentifier":"500168","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hwan-ChulYu"}],"nameIdentifiers":[{"nameIdentifier":"500169","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"前川, 康成"}],"nameIdentifiers":[{"nameIdentifier":"500170","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"廣木, 章博"}],"nameIdentifiers":[{"nameIdentifier":"500171","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kishiyama, Yoshihiro"}],"nameIdentifiers":[{"nameIdentifier":"500172","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shishitani, Hideyuki"}],"nameIdentifiers":[{"nameIdentifier":"500173","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamaguchi, Susumu"}],"nameIdentifiers":[{"nameIdentifier":"500174","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tanaka, Hirohisa"}],"nameIdentifiers":[{"nameIdentifier":"500175","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Koizumi, Satoshi"}],"nameIdentifiers":[{"nameIdentifier":"500176","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Appavou, Marie-Sousai"}],"nameIdentifiers":[{"nameIdentifier":"500177","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Houston, Judith"}],"nameIdentifiers":[{"nameIdentifier":"500178","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Radulescu, Aurel"}],"nameIdentifiers":[{"nameIdentifier":"500179","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Richter, Dieter"}],"nameIdentifiers":[{"nameIdentifier":"500180","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"ザオ ユエ","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"500181","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"吉村 公男","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"500182","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"前川 康成","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"500183","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"廣木 章博","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"500184","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Small angle neutron scattering study on the morphology of imidazolium-based grafted anion-conducting fuel cell membranes","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Small angle neutron scattering study on the morphology of imidazolium-based grafted anion-conducting fuel cell membranes"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-01-29"},"publish_date":"2019-01-29","publish_status":"0","recid":"49518","relation_version_is_last":true,"title":["Small angle neutron scattering study on the morphology of imidazolium-based grafted anion-conducting fuel cell membranes"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:19:19.709632+00:00"}
