METHOD OF LOADING INORGANIC NANOPARTICLES OR ORGANIC MOLECULES INTO POROUS PARTICLES OF MICRON OR SUBMICRON SIZE Russian patent published in 2020 - IPC B01D9/00 C09B1/46 C01G7/00 C01G49/02 C01F11/18 C08K5/92 

FIELD: chemistry.

SUBSTANCE: invention relates to loading porous particles of micron or submicron size with inorganic nanoparticles or organic molecules. Described is a method of loading inorganic nanoparticles or organic molecules into porous particles of micron or submicron size, involving obtaining a suspension of inorganic nanoparticles or organic molecules and porous particles in an aqueous medium or in an organic solvent medium; controlled suspension freezing with rate of crystallization front lower than critical speed, at which particles are captured by front, wherein freezing is carried out while stirring with speed, at which there is no sedimentation of particles; thawing of suspension; and recovering loaded porous particles, as well as a method of producing micron or submicron-size polymer capsules, comprising obtaining porous micronized or submicron sized particles, forming a polymer shell on the surface of said loaded porous particles of micron or submicron size, dissolving porous particles of micron or submicron size by processing with a reagent which dissolves porous particles, as well as a polymer capsule containing inorganic nanoparticles and/or organic molecules.

EFFECT: technical result is higher efficiency of loading inorganic nanoparticles or organic molecules into porous particles of micron or submicron size or polymer capsules.
