By electrophoresis approach makes superfine diamond deposition obtained at the cathode, carbon nanotube composite materials with ultrafine diamond

Field emission cathode materials research has attracted the eyes of many researchers . The field emission cathode for now , most of the reported a mere carbon nanotube film and diamond film . Carbon nanotubes have been shown to have good field emission characteristics , but also has a negative superfine diamond affinity and low . Therefore, considering the above factors , the ultrafine diamond carbon  cutting tools  and field emission properties of the material has a certain significance . In the preparation of synthetic materials , considering the ultrafine diamond in some organic solvents as its surface will absorb some of the charged ions , it will take a weak voltage. So make way through electrophoresis  synthetic diamond powder  deposition on the cathode to get this diamond ultrafine carbon nanotubes with the preparation of synthetic materials has important significance. Electrophoresis method used in the experiment , the diamond superfine the cathode substrate, thereby preparing a synthetic material , such an  Diamond blade  the PECVD method of carbon nanotubes on a substrate and the diamond growth ultrafine synthetic materials compared to more economical simple and practical, and easier to control . Final testing of field emission characteristics of the samples , and a comparative analysis with separate layers deposited ultrafine diamond , diamond film and field emission properties of carbon nanotube film .
