The radiation-induced graft polymerization of an ethyl 4-styrenesulfonate (ETSS) monomer onto PEEK substrates, with divinylbenzene (DVB) (0.05, 0.1, 0.2, and 0.5wt.%) as a crosslinker, followed by hydrolysis, generated crosslinker-containing PEEK-PEMs (PEEK-×0.05, -×0.1, -×0.2, and -×0.5), because the crosslinker (up to 0.5wt.%) did not cause any destructive effect on the on grafting and hydrolysis rates. As a result, grafting degrees of 100–114% and ion exchange capacities (IECs) of 2.2–2.7 mmol/g, respectively, were achieved. Increasing the DVB amounts (from 0 to 0.5 wt.%), the conductivity, and water uptakes decreased; the PEEK-×0.5 showed a conductivity of 0.10 S/cm and water uptake of 43%. This confirms the successful incorporation of crosslinking structures on the graft-polymers. The hydrothermal test involved the immersion of PEMs in water at 120 °C for 500 hours. The no-crosslinked PEEK-PEMs with the same IEC (2.7 mmol/g) experienced a decreases in the weight and IEC to 84 and 68% levels from the initial values, respectively, while those of crosslinked PEEK-×0.05 almost maintained their initial values (100 and 96%, respectively). These results indicated that very small amounts of crosslinkers can decreases the conductivity and the water absorption tendency while increasing the hydrothermal stability at higher temperatures.","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.radphyschem.2019.108647","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.sciencedirect.com/science/article/pii/S0969806X19312216","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0969-806X","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":"Hasegawa, Shin"}],"nameIdentifiers":[{"nameIdentifier":"999469","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hiroki, Akihiro"}],"nameIdentifiers":[{"nameIdentifier":"999470","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Maekawa, Yasunari"}],"nameIdentifiers":[{"nameIdentifier":"999471","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ohta, Yuko"}],"nameIdentifiers":[{"nameIdentifier":"999472","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Iimura, Nobuaki"}],"nameIdentifiers":[{"nameIdentifier":"999473","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fukaya, Atsuko"}],"nameIdentifiers":[{"nameIdentifier":"999474","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shin, Hasegawa","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"999475","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Akihiro, Hiroki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"999476","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Yasunari, Maekawa","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"999477","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":"Thermally stable graft-type polymer electrolyte membranes consisting based on poly (ether ether ketone) and crosslinked graft-polymers for fuel cell applications","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Thermally stable graft-type polymer electrolyte membranes consisting based on poly (ether ether ketone) and crosslinked graft-polymers for fuel cell applications"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-12-23"},"publish_date":"2019-12-23","publish_status":"0","recid":"78214","relation_version_is_last":true,"title":["Thermally stable graft-type polymer electrolyte membranes consisting based on poly (ether ether ketone) and crosslinked graft-polymers for fuel cell applications"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:45:00.359043+00:00"}
