Fundamental and applied studies of TEMPO-oxidized cellulose nanofibers and their related researches are reviewed, primarily based on the results obtained in our laboratory and by collaboration. When TEMPO-mediated oxidation in water is applied to bleached wood kraft pulps for papermaking, C6-carboxylate groups are efficiently and position-selectively formed on the surfaces of wood cellulose microfibrils. TEMPO-oxidized wood celluloses having sufficient amounts of sodium carboxylate groups can be converted to individualized cellulose nanofibers with almost uniform widths of 4 nm and lengths \u003e1 \u00b5m by mild mechanical disintegration in water. Electrostatic repulsion and/or osmotic effect efficiently work between anionically charged TEMPO-oxidized wood cellulose microfibrils, resulting in the formation of the individual nanofibers with high aspect ratios and high crystallinity. Cast films prepared from the TEMPO-oxidized cellulose nanofiber (TOCN)/water dispersions have high optical transparency, extremely low oxygen permeability, low thermal expansion coefficients, high strengths and other unique properties. The new cellulose-based nanofiber films are expected to be applied as transparent packaging materials with a high oxygen barrier for foods and medicines, flexible display panels, electronic devices, health care and other uses. Thus, TOCNs prepared from abundant wood biomass have great potential as novel bio-based nanofibers in state-of-the-art material fields required for the establishment of a sustainable society.", "subitem_description_type": "Abstract"}]}, "item_4_full_name_3": {"attribute_name": "\u8457\u8005\u5225\u540d", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "53504", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "ISOGAI, Akira"}]}]}, "item_4_publisher_20": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "\u6771\u4eac\u5927\u5b66\u5927\u5b66\u9662\u8fb2\u5b66\u751f\u547d\u79d1\u5b66\u7814\u7a76\u79d1\u9644\u5c5e\u6f14\u7fd2\u6797"}]}, "item_4_source_id_10": {"attribute_name": "\u66f8\u8a8c\u30ec\u30b3\u30fc\u30c9ID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00162451", "subitem_source_identifier_type": "NCID"}]}, "item_4_source_id_8": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "03716007", "subitem_source_identifier_type": "ISSN"}]}, "item_4_subject_15": {"attribute_name": "\u65e5\u672c\u5341\u9032\u5206\u985e\u6cd5", "attribute_value_mlt": [{"subitem_subject": "610", "subitem_subject_scheme": "NDC"}]}, "item_4_text_21": {"attribute_name": "\u51fa\u7248\u8005\u5225\u540d", "attribute_value_mlt": [{"subitem_text_value": "The University of Tokyo Forests"}]}, "item_4_text_34": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"subitem_text_value": "Departmental Bulletin Paper"}]}, "item_4_text_4": {"attribute_name": "\u8457\u8005\u6240\u5c5e", "attribute_value_mlt": [{"subitem_text_value": "\u6771\u4eac\u5927\u5b66\u5927\u5b66\u9662\u8fb2\u5b66\u751f\u547d\u79d1\u5b66\u7814\u7a76\u79d1\u751f\u7269\u6750\u6599\u79d1\u5b66\u5c02\u653b\u88fd\u7d19\u79d1\u5b66\u7814\u7a76\u5ba4"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "\u78ef\u8c9d, \u660e"}], "nameIdentifiers": [{"nameIdentifier": "53503", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2017-06-09"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "esrh126001.pdf", "filesize": [{"value": "23.9 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 23900000.0, "url": {"label": "esrh126001.pdf", "url": "https://repository.dl.itc.u-tokyo.ac.jp/record/25243/files/esrh126001.pdf"}, "version_id": "35606fc6-e5b1-47e5-b7d1-d07597be5a92"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "TEMPO \u9178\u5316\u30bb\u30eb\u30ed\u30fc\u30b9\u30ca\u30ce\u30d5\u30a1\u30a4\u30d0\u30fc\u306e\u8abf\u88fd\u3068\u7279\u6027\u89e3\u6790", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "TEMPO \u9178\u5316\u30bb\u30eb\u30ed\u30fc\u30b9\u30ca\u30ce\u30d5\u30a1\u30a4\u30d0\u30fc\u306e\u8abf\u88fd\u3068\u7279\u6027\u89e3\u6790"}]}, "item_type_id": "4", "owner": "1", "path": ["9/504/2469/2490", "27/2466/2467/2489"], "permalink_uri": "http://hdl.handle.net/2261/51466", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2012-07-17"}, "publish_date": "2012-07-17", "publish_status": "0", "recid": "25243", "relation": {}, "relation_version_is_last": true, "title": ["TEMPO \u9178\u5316\u30bb\u30eb\u30ed\u30fc\u30b9\u30ca\u30ce\u30d5\u30a1\u30a4\u30d0\u30fc\u306e\u8abf\u88fd\u3068\u7279\u6027\u89e3\u6790"], "weko_shared_id": null}
