VI. Description of the invention: [Technical Field of the Invention] [0001] The present invention relates to a conductive tape and a method of manufacturing the same. [Prior Art] [0002] In scanning electron microscopy (SEM) and X-ray energy spectroscopy (EDS) analysis, it is often necessary to use an electrically conductive and viscous object to fix the sample to be observed. At present, a very wide range of Carbon Conductive Tape (CCT) is used, in which the charcoal is indefinite. [0003] However, the above-mentioned carbon conductive tape has two disadvantages: the resistance of the first series is very large, generally at the level of about 700 KQ/cin; the cost of the second system is relatively high (usually, the price of a roll of 8 nm x 20 m carbon conductive tape is about 300 RMB) 〇 [Summary of the Invention] [0004] In view of the above, it is necessary to provide a conductive tape having low electrical resistance and low cost and a method of manufacturing the same.

[0007] The conductive tape has a carbon nanomaterial in an adhesive layer, and its conductivity is superior to that of amorphous carbon, so the conductive adhesive material containing carbon nanomaterial No. A〇101 is 4th. Page / Total 11 pages 1013368833-0 1378133 .· On September 27, 101, the replacement of the page strip has a low resistance; when preparing the conductive tape, to achieve the same conductivity, the amount of carbon nanotubes will be less. Therefore, the cost of the conductive tape is low. [0008] The method for manufacturing a conductive tape is simple and low in cost by uniformly bonding a carbon nanomaterial and an adhesive to a substrate. [Embodiment] Hereinafter, embodiments of the present invention will be further described in detail with reference to the accompanying drawings. [0010] Referring to FIG. 1, an embodiment of the present invention provides a conductive tape 10 including a substrate 102 and an adhesive layer 104 formed on one side of the substrate. [0011] The substrate 102 may be selected from a relatively flexible polymer film such as a non-stick layer of a general transparent tape. [0012] In this embodiment, the adhesive layer 104 is a pressure-sensitive adhesive layer. The adhesive layer 104 comprises a carbon nano material and a rubber paste, wherein the carbon nano material may be a carbon nanotube, a carbon nanosphere or a mixture of the two, and the carbon nanotube may be selected from the multi-walled nanometer. Carbon tube, single-walled carbon nanotube or a mixture of the two. The carbon nanotubes can be prepared by a conventional method such as chemical vapor deposition, arc discharge or laser evaporation, and can be purified by centrifugation to obtain a carbon nanotube having a higher purity. At present, the mass production of carbon nanotubes is already achievable.

In the present embodiment, the carbon nanomaterial is a carbon nanotube having a ruthenium quality of 2 g and a dioxane volume of 400 ml. The carbon nanotubes and dichloroethane were mixed and continuously dispersed by a cell crusher for 15 minutes, and then dispersed by an ultrasonic cleaner for 30 minutes to obtain a dispersion. An optional step is to filter the dispersion using a 400 mesh screen which is designed to filter out some small clusters. Of course, if the size of the particle size in the dispersion is different, other screens may be used, or the size of the particle size is not particularly required, and the filtration step may be omitted. In the present embodiment, the organic vehicle has a quality of 30 g, which comprises 5 g of ethyl cellulose, 5 ml of dibutyl orthophthalate and 90 ml of terpineol. The dispersion was added to the organic vehicle, and then continuously dispersed by a cell crusher for 15 minutes, and then dispersed by an ultrasonic cleaner for 30 minutes to obtain the carbon nanomaterial. _126〇Production No. A_ Page 6 / Total u Page 1013368833-0 1378133 On September 27, 101, the replacement page conductive solution was corrected.

It should be noted that the quality, volume and dispersion time of the above materials may be increased or decreased depending on the actual situation to achieve a better effect, and need not be specifically limited to the present embodiment. The purpose of adding the organic vehicle to the obtained dispersion is to enhance the adhesiveness of the conductive solution of the carbon nanomaterial. Of course, if the tackiness of the conductive solution of the carbon nanomaterial is not particularly required, the step of adding the organic vehicle can be omitted.
