The ABC triblock copolymer comprises an ionic liquid (IL)-phobic A block, an IL-philic B block, and a photo/thermoresponsive C block containing azobenzene moieties. The IL-phobic A block forms a rigid micellar core in an IL over a wide temperature range and the photo/thermoresponsive C block undergoes upper critical solution temperature (UCST)-type phase transition in ILs. In concentrated polymer solution, the ABC triblock copolymer can form a percolated micellar network at low temperatures through aggregation of A and C blocks as physical crosslinks, bridged by IL-philic B blocks. In contrast, the ion gel undergoes structural transition to jammed micelles at high temperatures due to the disassembly of the thermoresponsive C block, resulting in significant softening of the ion gel. Importantly, the temperature dependences of the viscoelastic properties of the ion gel differ drastically depending on photo-irradiation conditions as the photoinduced isomerization of azobenzene moieties in the C block modulates the affinity between the polymer chain and IL. Utilizing this feature, photoinduced softening/hardening of the ion gel is realized at constant temperature. This study provides a promising strategy to control the rheological properties of nonvolatile soft materials via contactless light irradiation that could be exploited in various applications such as photoresponsive soft actuators and photo-healable soft materials.","subitem_description_type":"Abstract"}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Royal Society of Chemistry "}]},"item_2_relation_13":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1039/c8sm01578c","subitem_relation_type_select":"DOI"}}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1744683X","subitem_source_identifier_type":"ISSN"}]},"item_2_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Department of Chemistry and Biotechnology, Yokohama National University"},{"subitem_text_value":"Department of Chemistry and Biotechnology, Yokohama National University"},{"subitem_text_value":"Department of Chemistry and Biotechnology, Yokohama National University"},{"subitem_text_value":"Yokohama Natl Univ, Dept Chem & Biotechnol"},{"subitem_text_value":"Department of Chemistry and Biotechnology, Yokohama National University"},{"subitem_text_value":"Department of Chemistry and Biotechnology, Yokohama National University"}]},"item_2_version_type_18":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Tamate, Ryota"}],"nameIdentifiers":[{"nameIdentifier":"34900","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Usui, Ryoji"}],"nameIdentifiers":[{"nameIdentifier":"34901","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hashimoto, Kei"}],"nameIdentifiers":[{"nameIdentifier":"34902","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kitazawa, Yuzo"}],"nameIdentifiers":[{"nameIdentifier":"34903","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kokubo, Hisashi"}],"nameIdentifiers":[{"nameIdentifier":"34904","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Watanabe, Masayoshi"}],"nameIdentifiers":[{"nameIdentifier":"34905","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"B360158657","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=B360158657"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-12-06"}],"displaytype":"detail","filename":"C8SM01578C.pdf","filesize":[{"value":"4.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"C8SM01578C.pdf","url":"https://ynu.repo.nii.ac.jp/record/9423/files/C8SM01578C.pdf"},"version_id":"96683e4f-efee-4b0c-860a-f0c2f82aa1fb"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"THIN-FILM TRANSISTORS","subitem_subject_scheme":"Other"},{"subitem_subject":"POLYMER","subitem_subject_scheme":"Other"},{"subitem_subject":"LIQUID","subitem_subject_scheme":"Other"},{"subitem_subject":"HYDROGELS","subitem_subject_scheme":"Other"},{"subitem_subject":"MICELLIZATION","subitem_subject_scheme":"Other"},{"subitem_subject":"SPECTROSCOPY","subitem_subject_scheme":"Other"},{"subitem_subject":"RELAXATION","subitem_subject_scheme":"Other"},{"subitem_subject":"CHALLENGES","subitem_subject_scheme":"Other"},{"subitem_subject":"MORPHOLOGY","subitem_subject_scheme":"Other"},{"subitem_subject":"RHEOLOGY","subitem_subject_scheme":"Other"}]},"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":"Photo/thermoresponsive ABC triblock copolymer-based ion gels: photoinduced structural transitions","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Photo/thermoresponsive ABC triblock copolymer-based ion gels: photoinduced structural transitions"}]},"item_type_id":"2","owner":"3","path":["496"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-12-12"},"publish_date":"2018-12-12","publish_status":"0","recid":"9423","relation_version_is_last":true,"title":["Photo/thermoresponsive ABC triblock copolymer-based ion gels: photoinduced structural transitions"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-20T19:26:33.971154+00:00"}
