Nanoparticles from slightly oxidised cellulose

摘要

Preparing a dispersion containing particles made of slightly oxidized cellulose, comprises: (a) providing slightly oxidized, preferably non-nanoscale cellulose into an aqueous, preferably non-acidic medium; and (b) dispersing simultaneously or subsequently by the addition of energy, where the particle size (D50-value) is less than 300 nm, preferably less than 100 nm, determined by a dynamic laser scattering. An independent claim is included for a dispersion obtained by the above process.
