Abstract:
Provided are a cooling device coated with carbon nanotubes and method of manufacturing the same. Carbon nanotubes are dispersively coated on a surface of the cooling device that radiates generated by a predetermined apparatus or component through thermal exchange. Thus, a carbon nanotube structure is formed so that the cooling device can improve in a thermal radiation characteristic and become small-sized. As a result, electronic devices can be downscaled and heat generated by a highly integrated electronic circuit chip can be effectively radiated, thus increasing lifetime and performance of an operating circuit.

Abstract:
Provided is a method of forming electron emitter tips for a field emission display device (FED) using copper-carbon nanotube composite electroplating. In the method, a cathode substrate having a surface on which a copper seed layer is defined is provided. The cathode substrate is dipped along with an anode substrate in an electroplating tank that is filled with an electroplating solution containing carbon nanotubes and a copper electrolytic solution. Thereafter, a copper-carbon nanotube composite is electroplated on the cathode substrate by supplying power to the cathode substrate and the anode substrate. By forming the electron emitter tips using the copper-carbon nanotube composite electroplating, an FED having a good adhesion of carbon nanotubes with the substrate can be fabricated. Also, the FED can have high luminance and a long lifetime and consume low power.

The present invention relates to a touch panel. The touch panel, according to the present invention, comprises: a base material; and an adhesive layer, which is coupled to the base material and has a release force of 1900g/25mm with respect to a polycarbonate sheet, wherein the form of the adhesive layer includes an acrylic polymer product comprising an acrylic polymer and a thiol polymer, which is derived from a thiol compound that binds to a side chain or the end of a chain in the acrylic polymer, thereby effectively preventing oxygen, moisture, or other foreign substances from infiltrating a base material film and the surface of the adhesive layer or a conductive body thin film and the surface of the adhesive layer, and preventing deterioration of optical properties such as visibility, due to bubbles that are generated form an adhesive surface. In addition, change in resistance of the conductive body thin film is effectively prevented when the adhesive layer is directly coupled to the conductive body thin film and when exposed to extreme conditions, such as high temperature or high temperature and high humidity, thereby enabling stable operation of the touch panel for a long time.
Abstract:
The present invention relates to a method for manufacturing a molybdenum sputtering target for a back surface electrode of a CIGS solar cell. The method for manufacturing the molybdenum sputtering target includes: a step of filling molybdenum powder into a mold formed of a graphite material; a step of mounting the mold, in which the molybdenum powder is filled, inside a chamber of a discharge plasma sintering device; a step of forming a vacuum state inside the chamber; a step of increasing the temperature of the molybdenum powder within the mold according to a preset temperature increase pattern in a state where the molybdenum powder is maintained under a predetermined pressure to perform a formation process until the temperature of the molybdenum power reaches a final target temperature; a step of further maintaining the final target temperature for about 1 minute to 10 minutes; and a step of cooling the inside of the chamber while maintaining the predetermined pressure. According to the method for manufacturing the molybdenum sputtering target for a CIGS solar cell, when a sintered body suitable for the sputtering target is manufactured using a discharge plasma sintering process, high density may be achieved. Also, since a single process is performed for a short time, a sintered body having a uniform structure and high purity without causing particle growth may be manufactured.
