Abstract: The present invention relates to individual cellulose nanofibrils decorated with magnetic nanoparticles made of transition metal ions or an oxide thereof, as well as a method for the preparation thereof. The method of the present invention is performed in an oxidizing atmosphere, which gives a complete oxidation of the metal ions to hydroxide/oxide complexes and affords a strong attachment of the obtained complexes to the cellulose nanofibrils. The resulting metal ion complexes attach to the nanofibrils prior to the formation of the magnetic nanoparticles, thus preventing associations and agglomerations of the precipitated magnetic nanoparticles. Applications for the present invention include water purification, catalysis and biomedical applications.

Abstract: There is provided cellular sol id materials comprising at least 50 wt% cellulose nanofibers (CNF), as calculated on the total weight of the cellular solid material, and a surfactant, wherein: a) the surfactant is anionic; b) the material has a density of less than 500 kg/m3; and c) at least 50% of the cells of the material have a diameter of at least 10 µm. Also provided are methods for manufacturing a dried cellular solid material with a density of less than 500 kg/m3, comprising the steps of: (a) providing a dispersion comprising cellulose nanofibers (CNF) in an aqueous solvent, (b) adding an anionic surfactant to the dispersion in (a) to obtain a mixture; (c) preparing a wet foam from the mixture obtained in (b), wherein the wet foam has a density less than 98% of the mixture prepared in (b); and (d) drying the wet foam obtained in (c) to obtain the cellular solid material. Uses of the cellular solid materials are also provided.
