METHOD FOR OBTAINING FIBROUS MATERIAL CONTAINING OXIDE NANOPARTICLES FROM THERMOPLAST MELT Russian patent published in 2017 - IPC D01D5/08 B82B3/00 

FIELD: chemistry.

SUBSTANCE: method, like the prototype, involves forming a fibrous material by laminating a melt of a thermoplastic polymer by the action of a gas stream containing solid particles. Particles penetrate into the surface layer of the softened material, and particle consolidation occurs, when the material passes into a solid aggregate state. New is that the formation of fibers occurs under the influence of an unheated gas stream containing oxide nanoparticles or small droplets of liquid, in which such nanoparticles having an ambient temperature are dispersed. Gas ejection is provided, in which an additional flow of unheated gas is generated around the jet of molten polymer fed. The particle size is less than 100 nm.

EFFECT: production of fibrous material with oxide nanoparticles fixed on its surface with one or, at least, two kinds, with minimal energy costs and simplification of the technological process.
