Beschreibung
Zusammenfassung:	The present invention relates to a structure for the controlled release of at least one active substance, where the structure comprises the active substance and a cellular solid material comprising cellulose nanofibers (CNF). The structure has a density of less than 1000 kg/m3, and the cellular solid material comprises closed cells. The invention further relates to a method for preparing the structure; as well as the use of the structure. L'invention porte sur une structure de libération contrôlée d'au moins une substance active, la structure comprenant une substance active et une matière cellulaire solide comprenant des nanofibres de cellulose (CNF). La structure a une densité inférieure à 1000 kg/m3, et la matière cellulaire solide comprend des alvéoles fermés. L'invention porte également sur une procédure de préparation de la structure, ainsi que son utilisation.
