Title (EN) POROUS NANOCRYSTALLINE CELLULOSE STRUCTURES
(FR) STRUCTURES CELLULOSIQUES NANOCRISTALLINES POREUSES
Abstract:
(EN) The invention disclos a class of foam materials characterized by regions of material unidirectionality. After acidic hydrolysis of cellulose, the obtained cellulose crystals are suspended in water and unidirectionally frozen. The porous product obtained after solvent exchange and drying shows a structure of unididirectionally oriented pores.
(FR) Cette invention concerne une classe de matériaux de mousse caractérisés par des régions à orientation unidirectionnelle des matériaux. Après hydrolyse acide de la cellulose, les cristaux de cellulose obtenus sont suspendus dans l'eau et congelés selon une orientation unidirectionnelle. Le produit poreux obtenu après échange de solvants et séchage montre une structure dont les pores présentent une orientation unidirectionnelle.
