These AEMs were prepared by radiation-induced grafting of 2-methyl-1-vinylimidazole and styrene into poly(ethylene-co-tetrafluoroethylene) (ETFE) films and a subsequent N-alkylation with methyliodide, and possessed both high alkaline durability and high conductivity. Our results showed that the crystalline lamellar and crystallite structures originating from the pristine ETFE films were more or less conserved in these AEMs, but the lamellar d-spacing in both dry and wet membranes were enlarged, indicating an expansion of the amorphous lamellae due to the graft chains introduced in the grafting process and the water incorporated in the swelling process. For the first time, the swelling behavior of the AEMs was studied quantitatively in various water mixtures of water and deuterated water with different volume ratios (contrast variation method), and the morphology of these membranes was elucidated by three phases: phase 1) crystalline ETFE domains, which offer good mechanical properties; phase 2) hydrophobic amorphous domains, which are made up of amorphous ETFE chains and offer a matrix to create conducting regions; phase 3) interconnected hydrated domains, which are composed of the entire graft chains and water and play a key role to promote the conductivity.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Royal Society of Chemistry"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1039/c5sm02724a","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1744-683X","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":"Zhao, Yue"}],"nameIdentifiers":[{"nameIdentifier":"480531","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yoshimura, Kimio"}],"nameIdentifiers":[{"nameIdentifier":"480532","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shishitani, Hideyuki"}],"nameIdentifiers":[{"nameIdentifier":"480533","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yamaguchi, Susumu"}],"nameIdentifiers":[{"nameIdentifier":"480534","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tanaka, Hirohisa"}],"nameIdentifiers":[{"nameIdentifier":"480535","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Koizumi, Satoshi"}],"nameIdentifiers":[{"nameIdentifier":"480536","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Szekely, Noemi"}],"nameIdentifiers":[{"nameIdentifier":"480537","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Radulescu, Aurel"}],"nameIdentifiers":[{"nameIdentifier":"480538","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Richter, Dieter"}],"nameIdentifiers":[{"nameIdentifier":"480539","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Maekawa, Yasunari"}],"nameIdentifiers":[{"nameIdentifier":"480540","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"ザオ ユエ","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"480541","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"吉村 公男","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"480542","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"前川 康成","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"480543","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":"Imidazolium-Based Anion Exchange Membranes For Alkaline Anion Fuel Cells: Elucidation of the Morphology and the Interplay Between Morphology and Properties","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Imidazolium-Based Anion Exchange Membranes For Alkaline Anion Fuel Cells: Elucidation of the Morphology and the Interplay Between Morphology and Properties"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-04-27"},"publish_date":"2017-04-27","publish_status":"0","recid":"47864","relation_version_is_last":true,"title":["Imidazolium-Based Anion Exchange Membranes For Alkaline Anion Fuel Cells: Elucidation of the Morphology and the Interplay Between Morphology and Properties"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:34:42.250835+00:00"}
