Title (EN) CELLULOSE NANOFIBER CARBON AND METHOD FOR MANUFACTURING SAME
(FR) CARBONE DE NANOFIBRES DE CELLULOSE ET PROCÉDÉ DE PRODUCTION DUDIT CARBONE
(JA) セルロースナノファイバーカーボンとその製造方法
Abstract:
(EN) Provided is a cellulose nanofiber carbon for which the specific surface area can be increased and a method for manufacturing the same. This method for manufacturing a cellulose nanofiber carbon thermally treats a cellulose nanofiber to carbonize the same and involves: a freezing step S2 of freezing a solution or gel that includes the cellulose nanofiber to obtain a frozen body; a drying step S3 of drying the frozen body in a vacuum to obtain a dried body; and a carbonizing step S4 of heating and carbonizing the dried body in an atmosphere that does not cause the dried body to combust in order to obtain the cellulose nanofiber carbon.
(FR) L'invention concerne un carbone de nanofibres de cellulose pour lequel la surface spécifique peut être augmentée et un procédé pour produire ledit carbone. Le procédé pour produire un carbone de nanofibres de cellulose traite thermiquement une nanofibre de cellulose en vue de carboniser ladite nanofibre et comprend : une étape de congélation S2 consistant à congeler une solution ou un gel qui comporte la nanofibre de cellulose en vue d'obtenir un corps congelé ; une étape de séchage S3 consistant à sécher le corps congelé sous vide en vue d'obtenir un corps séché ; et une étape de carbonisation S4 consistant à chauffer et à carboniser le corps séché dans une atmosphère qui ne provoque pas la combustion du corps séché afin d'obtenir le carbone de nanofibres de cellulose.
(JA) 比表面積を大きくすることが出来るセルロースナノファイバーカーボンとその製造方法を提供する。セルロースナノファイバーを熱処理することでカーボン化するセルロースナノファイバーカーボンの製造方法であって、セルロースナノファイバーを含む溶液またはゲルを凍結させて凍結体を得る凍結工程S2と、凍結体を真空中で乾燥させて乾燥体を得る乾燥工程S3と、乾燥体を燃焼させない雰囲気中で加熱して炭化させてセルロースナノファイバーカーボンを得る炭化工程S4とを含む。
