DEVICE FOR COAXIAL ELECTROHYDRODYNAMIC FORMATION OF POLYMER MICRO- OR SUBMICRONE STRUCTURES Russian patent published in 2019 - IPC B05B5/03 B81C3/00 

FIELD: chemistry.

SUBSTANCE: invention relates to devices for coaxial electroforming of polymer capsules or micro- and submicron-sized fine fibres. Technical result is achieved by device for coaxial electro-hydrodynamic moulding of polymer micro- or submicron structures, containing coaxial external capillary for supply of polymer solution and internal capillary for supply of encapsulated substance, fixed in housing and connected to first high voltage source, settling electrode. Device additionally comprises a confusor located between the housing and the grounded precipitation electrode, having channels for feeding gas into the space between the confusor and the grounded precipitation electrode, as well as a second high-voltage source connected to the precipitation electrode.

EFFECT: technical result is possibility of formation of micro- and submicron structures of certain geometric shape from polymer solutions of low viscosity and improved quality of coatings of micro- and submicron structures due to uniform spraying of polymer solution.
