Ceramic paste composition using carbon nanotube or carbon nanotube-metal composite and conductive film containing the same

摘要

Provided is a ceramic paste composition including carbon nanotubes or a carbon nanotube-metal composite and a silicone adhesive, wherein the silicone adhesive includes 45 to 65 wt% of silicon dioxide, and 0.1 to 10 wt% of a silanol group, and has a weight ratio of a methyl group: a phenyl group of 1: 0.3 to 2.5. The ceramic paste composition according to the present invention is characterized by having low sheet resistance, through which an excellent heat generating property, and shielding, absorbing and conducting properties may be implemented. Further, though the ceramic paste composition has a very high heat generating temperature of 400 °C, as compared with general paste based on carbon nanotubes, the physical properties thereof may be maintained stably, thereby implementing the inherent properties of ceramic paste. In addition, the ceramic paste may be easily formed into a planar conductive film by a simple process, and thus, widely used in various fields including heat generating products such as those for keeping warmth or heating, and products for electromagnetic wave shielding and absorption, electrodes, electronic circuits, antennas, and the like.
