Details:
CNTs-Black Carbon Prepared by Electrostatic Adsorption:
CNTs (Outside diameter: >50nm, Inside diameter: 5-15nm, length: 5-20um)--treated by Cationic surfactant (Cetyl trimethyl ammonium bromide); The Super Conductive Black Carbon Nanoparticles (Size: 50nm~100nm, particles shape: spherical)--Carbon black surface is usually negatively charged. The black carbon and CNTs through Electrostatic adsorption self-assembly form a uniform and stable complex. Carbon black nanoparticles effectively isolate the agglomerations of CNTs and form stable CNTs/Carbon Black composite. Carbon black has a large surface area with electronegativity, therefore, the carbon black nanoparticles can adsorb more of CNTs.

The Product Apllication:
CNTs by electrostatic adsorption self-assembly to the high conductivity of carbon black nanoparticles surface to form a "bunch of grapes" complex structure, fibrous CNTs stems, spherical conductive carbon black grapes. The property of structural synergies conductive efficiency makes CNTs to give the material higher strength and wear resistance, suitable for processing into the conductive sheet and suitable for processing into clean, wear-resistant sheet. Good processing and mechanical properties, suitable to be added to the high content of carbon black conductive plastic, such as fuel cell bipolar plates. Recommended that the CNTs/Carbon Black composite can be used in other areas conductive sheet, conductive film, and high-conductive plastics....
