Provided herein is a spray nozzle and a coating system using the same, the spray nozzle and the coating system comprising a liquid nozzle injecting liquid towards a substrate; a gas nozzle for injecting gas to collide with the liquid on an injection path of the liquid to perform a primary atomization of the liquid; and a voltage supply connected to the liquid nozzle, the voltage supply for applying voltage to the liquid nozzle to generate an electric field between the liquid nozzle and substrate to perform a secondary atomization of the liquid.


The present invention provides a droplet jetting apparatus which jets fluid in a droplet shape. The apparatus includes a main body (100), which has a chamber (110) for containing fluid. The main body further has at least one nozzle (120) which communicates with the chamber and jets a droplet onto a printable matter, and a first electrode (130) which is formed on the inner surface of at least one selected from between the nozzle and the chamber by patterning treatment to make electrical contact with the fluid. The apparatus further includes a second electrode (140), which is provided between the nozzle and the printable matter and has a through hole, through which the droplet is jetted from the nozzle onto the printable matter, a power supply (200) which supplies a voltage applied between the first electrode and the second electrode, and a control unit (300) which controls the power supply.


There is disclosed an apparatus for spraying and patterning, using an electrostatic force, includes a nozzle to which a voltage is applied to exhaust ink, a droplet circulation chamber provided in one end of the nozzle, with a hole provided in one end to spray the ink exhausted from the nozzle based on a particle size of the droplet and to temporarily collect the not-sprayed ink, and a substrate for impacting the ink sprayed from the hole thereon by forming an electric field between the nozzle and the substrate.


Disclosed is a conductive nano ink composition which contains 0.05 to 15 parts by weight of a high molecular compound having a molecular weight of 100,000 to 1,000,000 and comprising at least one between a natural high-molecular compound and a synthetic high-molecular compound; 1 to 6 parts by weight of a wetting dispersant; and 10 to 100 parts by weight of an organic solvent, per 100 parts by weight of a conductive nano structure, thereby providing an electrode line having a narrow line width due to its uniform viscosity and excellent electrical properties. Further, it is possible to provide a transparent electrode excellent in light transmittance and electric conductivity as it is patterned using the conductive nano ink composition.
