Abstract:
(EN) Provided are: a cellulose nanofiber liquid dispersion containing 0.01-30 wt% of a chemically-modified cellulose, 0.01-20 wt% of a surfactant, and 50-99.8 wt% of a dispersion solvent, wherein the chemically-modified cellulose is a fine powder which has undergone half-esterification to modify a hydroxy group contained in the cellulose with a dibasic acid anhydride, and the surfactant is at least one selected from surfactants that have a surface tension of 70 m·N/m or less as measured by the Wilhelmy method, and that result in a contact angle of 90° or less between droplet and solid surface; a cellulose nanofiber composite resin; and production methods for the cellulose nanofiber liquid dispersion and the cellulose nanofiber composite resin.
(FR) L'invention concerne : une dispersion liquide de nanofibres de cellulose contenant de 0,01 à 30 % en poids de cellulose chimiquement modifiée, de 0,01 à 20 % en poids de tensioactif, et de 50 à 99,8 % en poids de solvant de dispersion, où la cellulose chimiquement modifiée est une poudre fine qui a subi une demi-estérification pour modifier un groupe hydroxy contenu dans la cellulose avec un anhydride d'acide dibasique, et le tensioactif est au moins un tensioactif choisi parmi les tensioactifs ayant une tension superficielle, mesurée par le procédé de Wilhelmy, de 70 m·N/m ou moins, et qui engendrent un angle de contact de 90 ° ou moins entre une gouttelette et une surface solide ; une résine composite à base de nanofibres de cellulose ; et des procédés de production de la dispersion liquide de nanofibres de cellulose et de la résine composite à base de nanofibres de cellulose.
(JA) 化学修飾セルロースを0.01~30wt%と、界面活性剤を0.01~20wt%と、分散溶媒を50~99.8wt%とを含むセルロースナノファイバー分散液であって、前記化学修飾セルロースは、セルロースに含まれる水酸基に対して二塩基酸無水物を修飾する半エステル化処理された微粉末の化学修飾セルロースであり、前記界面活性剤は、ウィルヘルミー法による表面張力の測定値が70m・N/m以下であって、かつ液滴と固体表面の接触角が90°以下の界面活性剤より選択される少なくとも1種であるセルロースナノファイバー分散液、セルロースナノファイバー複合樹脂、及びそれらの製造方法。
