Water content (W_c) of the obtained PU hydrogels was less than 3.0 g g^<-1> and NCO/OH ratio was varied from 0.05 to 0.6 mol mol^<-1>. Phase transitions of NaCS and NaCS-PU hydrogels were measured by differential scanning calorimetry (DSC). From DSC curves, glass transition temperature (T_g), melting peak at low temperature (T_<ml>), melting peak at high temperature (T_<mh>) and liquid crystal transition temperature (T_<lc>) were obtained. It was also confirmed that there were three kinds of water, non-freezing water, freezing bound water, and freezing water. T_g decreased in a W_c from 0.05 to 1.0 g g^<-1>, reached a minimum and then increased W_c from 1.0 to 3.0 g g^<-1>. The T_g lowest value increased with increasing NCO/OH ratio indicating that molecular motion was restricted by cross-linking. The nano level structures of NaCS and NaCS-PU hydrogels were observed by atomic force microscopy (AFM).","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.57375/00000461","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"福井工業大学"}]},"item_10002_relation_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"TF00008920","subitem_relation_type_select":"NCID"}}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2868571","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"大西, 徹"}],"nameIdentifiers":[{"nameIdentifier":"10068","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"畠山, 兵衛"}],"nameIdentifiers":[{"nameIdentifier":"10069","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Onishi, Toru","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"10070","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hatakeyama, Hyoe","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"10071","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2023-04-12"}],"displaytype":"detail","filename":"KJ00004437936.pdf","filesize":[{"value":"723.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00004437936.pdf","url":"https://fut.repo.nii.ac.jp/record/467/files/KJ00004437936.pdf"},"version_id":"daabd3b4-e38d-49dd-98fd-72a966396e6c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"sodium cellulose sulfate","subitem_subject_scheme":"Other"},{"subitem_subject":"polyurethane","subitem_subject_scheme":"Other"},{"subitem_subject":"hydrogels","subitem_subject_scheme":"Other"},{"subitem_subject":"phase transition","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"化学架橋硫酸セルロースナトリウム塩ヒドロゲルのナノレベル構造と熱的性質","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"化学架橋硫酸セルロースナトリウム塩ヒドロゲルのナノレベル構造と熱的性質"},{"subitem_title":"Nano Level Structure and Thermal Properties of Chemically Cross-linked Sodium Cellulose Sulfate Hydrogels","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"2","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-04-04"},"publish_date":"2009-04-04","publish_status":"0","recid":"467","relation_version_is_last":true,"title":["化学架橋硫酸セルロースナトリウム塩ヒドロゲルのナノレベル構造と熱的性質"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-06-20T14:31:53.064683+00:00"}
