Surface modification and characterization of carbon black with oxygen plasma

Influence of Plasma Treatment on Microstructures and Acid–Base Surface Energetics of Nanostructured Carbon Blacks: N2 Plasma Environment

“…Among these, the interaction of the plasma treatment with carbon surfaces produces highly active species, such as free radicals, ions, and metastable species, which cause ablation, crosslinking, and oxidation reactions, depending on the nature of the gases used in the plasma zone (6,(13)(14)(15). There are two principal advantages to mild plasma treatment method for materials: (1) the reaction takes place only on the material surface without significantly changing bulk properties, and (2) it is possible to make any atmosphere, such as oxidative, reductive, and inactive.…”

Zeta Potential as a Tool to Characterize Plasma Oxidation of Carbon Fibers

“…medium for the surface chemical modification of different Samples, ground to õ63 mm, were treated to various BO types of carbon materials, including graphites (1, 2), meso-degrees by varying the time of exposure to a microwave carbon microbeads (3)(4)(5), glassy carbons (6-8), carbon (2450 MHz) generated oxygen plasma. Treatments were blacks (9,10), and carbon fibers (11)(12)(13)(14)(15)(16)(17). The oxygen carried out in a Technics Plasma 200-G reactor at 150 W plasma treatment of the latter type of material deserves par-and with an oxygen flow rate to sustain 1.0 mbar pressure ticular interest as it can be used to improve the carbon fiber-inside the reaction chamber.…”

Manufacturing of Industrial Supercapacitors

“…Many treatments have been developed for surface modification of carbon for electrochemical applications: acid treatment [147,148], oxidizing [149][150][151], electrochemical [152], thermal [153], by laser [154], by plasma [155,156], by polishing [157], or by washing in a solvent [158], hydrogenation followed by a sulfonation [159], a first halogenation step by chlorine or bromine and a second step consisting in a dehalogenation under hydrogen [160] and so on.…”
