The silica particles were treated with a 2-propanol solution and heated at 120℃ for 24 h after solvent evaporation. For multilayer coverage, the linear chain and network structures were expected to form on the surface by a polycondensation reaction using the di-and trialkoxy structures, respectively. However, the rigid network structure was formed from both the di-and trialkoxy structures for both glycidoxy and amino functional silanes. Fourier transform infrared spectroscopic analysis revealed that a ring opening of the epoxy group occurred, followed by a reaction to form the network structure, even with the dialkoxy structure for the glycidoxy functional. The ring opening of the epoxy group could be reduced by setting the heating temperature at 80℃, and the linear chain structure was formed by di-alkoxy structure. In the case of the amino group, the network formation by the dialkoxy structure was seemed to be caused by the hydrogen bonding between the amino group and the silanol group on a silica surface.","subitem_description_language":"en","subitem_description_type":"Other"},{"subitem_description":"文化財保存に用いられているOH-100の成分であるシラン化合物は、シラン分子のアルコキシ基の数や有機官能基の種類により、補強する土壌との反応性や形成したシラン菫縮合体の硬さをコントロールすることが可能である。この点について基礎的に検討した。グリシドキシ基あるいはアミノ基を含有し、アルコキシ基の数が2と3のシランカップリング剤で球状シリカ粒子の表面処理を行い、多分子被覆層のシラン分子鎖の運動性を¹Hパルス核磁気共鳴（パルスNMR) で評価した。パルスNMR測定の結果、グリシドキシ基では処理後の加熱温度が120℃の場合、アルコキシ基の数が2、3ともにシラン鎖はリジッドであった。赤外分光分析から加熱でエポキシ基の開環が起こり、アルコキシ基による網目形成反応に関与している可能性が示された。加熱温度80℃では，アルコキシ基の数が2の場合はシラン鎖がフレキシブルであった。アミノ基の場合も、アルコキシ基の数が2、3ともにシラン鎖はリジッドであった。アミノ基とシリカ表面のシラノール基との水素結合の影響と考えられる。また、アルコキシ基の数が2より3の方がわずかに緩和がゆるやかであった。熱重量分析から、アルコキシ基の数が3の場合は、2の場合より吸着水がシラン処理層により多く残存しており、これが影響したものと推定した。","subitem_description_language":"ja","subitem_description_type":"Other"}]},"item_10_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.32286/0002000238","subitem_identifier_reg_type":"JaLC"}]},"item_10_publisher_34":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"関西大学文化財保存修復研究拠点","subitem_publisher_language":"ja"},{"subitem_publisher":"Institute for Conservation and Restoration of Cultural Properties, Kansai University","subitem_publisher_language":"en"}]},"item_10_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"BB04028363","subitem_source_identifier_type":"NCID"}]},"item_10_version_type_17":{"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_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"中村, 吉伸","creatorNameLang":"ja"},{"creatorName":"Nakamura, Yoshinobu","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"福田, 知由","creatorNameLang":"ja"},{"creatorName":"Fukuda, Tomoyoshi","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"山村, 和広","creatorNameLang":"ja"},{"creatorName":"Yamamura, Kazuhiro","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"藤井, 秀司","creatorNameLang":"ja"},{"creatorName":"Fujii, Syuji","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2023-09-06"}],"displaytype":"detail","filename":"KU-0040-20130304-19.pdf","format":"application/pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://kansai-u.repo.nii.ac.jp/record/2000238/files/KU-0040-20130304-19.pdf"},"version_id":"18165632-9c21-4f01-a41c-1f562becd4f6"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"エジプト","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"サッカラ","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"文化財","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"修復","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"関西大学","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"Kansai University","subitem_subject_language":"en","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":"シリカ粒子と反応したシラン重縮合体の硬度におよぼすシラン分子のアルコキシ基の数と有機官能基の影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"シリカ粒子と反応したシラン重縮合体の硬度におよぼすシラン分子のアルコキシ基の数と有機官能基の影響","subitem_title_language":"ja"}]},"item_type_id":"10","owner":"10","path":["106"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-09-06"},"publish_date":"2023-09-06","publish_status":"0","recid":"2000238","relation_version_is_last":true,"title":["シリカ粒子と反応したシラン重縮合体の硬度におよぼすシラン分子のアルコキシ基の数と有機官能基の影響"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2023-09-14T02:48:01.073292+00:00"}
