FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing a dispersion, consisting of microfibrillated cellulose and nanoparticles, which comprises preparing a slurry of pretreated cellulose fibres, wherein cellulose fibres are pretreated by mechanical processing, enzymatic treatment, carboxymethylation, oxidation action TEMPO, grafting CMC, chemical swelling or acid hydrolysis, introduction of nanoparticles into the slurry and treating slurry through mechanical breakdown such that dispersion is formed, comprising microfibrillated cellulose, wherein nanoparticles are absorbed on surface of microfibrillated cellulose and/or absorbed within microfibrillated cellulose.
EFFECT: invention also relates to a dispersion obtained according to technology, paper or cardboard products to be coated, consisting of said dispersion.
