PURPOSE: An electromagnetic wave shielding composition is provided to shield the electromagnetic wave just by coating the composition onto the surface of an electronic product. CONSTITUTION: The electromagnetic wave shielding composition comprises 10-30 wt% of carbon nanotube treated with lithium or potassium; 2-10 wt% of a polyol which becomes a phenol resin; 3-12 wt% of aldehydes; and the balance of a solvent selected from the group consisting of an alcohol of C1-C4, acetone and their mixtures. Also the electromagnetic wave shielding composition comprises 10-30 wt% of carbon nanotube treated with lithium or potassium; 2-10 wt% of a polyol which becomes a phenol resin; 3-12 wt% of aldehydes; 1-5 wt% of a pigment; 7-8 wt% of a dispersant; 7-8 wt% of a flowing improver; 7-8 wt% of an antifoaming agent; 7-8 wt% of a curing agent; and the balance of a solvent selected from the group consisting of an alcohol of C1-C4, acetone and their mixtures. |
