Abstract: front page image
(EN) The purposes of the present invention are: to provide a fluid -permeable porous body which contains cellulosic nanofibers that have extremely small fiber diameters and that exhibit high hydrophilicity; and to manufacture the porous body at a low cost. A porous body composed of a porous support that has many interconnected pores in which nanofibers are entangled with each other and thus form a network structure, characterized in that the nanofibers are cellulosic nanofibers having a number-average fiber diameter of 1 to 100nm.
(FR) Les objectifs de la présente invention sont : fournir un corps poreux perméable à un fluide qui contient des nanofibres cellulosiques qui ont des diamètres de fibre extrêmement petits et qui présentent un caractère hydrophile élevé ; et fabriquer le corps poreux à bas coût. L'invention concerne un corps poreux composé d'un support poreux qui a de nombreux pores communicants dans lesquels des nanofibres sont entremêlées les unes avec les autres et forment ainsi une structure en réseau, caractérisées en ce que les nanofibres sont des nanofibres cellulosiques ayant un diamètre de fibre moyen en nombre de 1 à 100 nm.
(JA) 本発明の目的は、極めて繊維径が細く、かつ、親水性の高いセルロース系ナノファイバーを含んでなる流体透過性のある多孔質体を提供すること及び多孔質体を低コストで製造することである。本発明に係る多孔質体は、多数の孔が連通した多孔質の支持体の孔内で、ナノファイバーが絡み合って網目状構造体を形成した多孔質体であって、前記ナノファイバーが、セルロース系ナノファイバーであり、かつ、数平均繊維径が1~100nmであることを特徴とする。
