Rapid oxidative activation of carbon nanotube yarn and sheet by a radio frequency, atmospheric pressure, helium and oxygen plasma

Fabrication and study of supercapacitor electrodes based on oxygen plasma functionalized carbon nanotube fibers

“…When these materials are used as electrode materials in an aqueous electrolyte system (as described above), the high ionic resistance between the surface of the electrode and aqueous electrolyte hinders the accessibility of the electrolyte ions into the electrode material regardless of its porosity [49,50] . Plasma functionalization has long been confirmed to increase the wettability of CNT and of other carbon-based materials [36,39,40,41,49] (Fig. S6).…”

“…CNTs by nature are hydrophobic and inert, making them unfavorable for specific applications such as in microfluidic devices. Wettability of carbon nanotubes has been altered by changing their chemical composition or structure, and this can be achieved by oxygen plasma functionalization [32,[35][36][37][39][40][41] .…”

Atmospheric pressure plasma treatment on graphene grown by chemical vapor deposition

“…Surface modification of carbon nanomaterials is being actively investigated. For example, the reduction of graphene oxide and the formation of surface functional groups on carbon nanotubes (CNT) using atmospheric pressure plasmas were reported [22,23].…”

PHOTOCATALYTIC PROPERTIES OF TiO2/CNTs FILMS WITH DIFFERENT MORPHOLOGY ON STAINLESS STEEL SUBSTRATES

“…2(c), the surface of CNTs is rough, and the hollow structure of CNTs is Oxygen plasma treatment is a very e±cient process for the functionalization of CNTs and C-Ox groups can be generated on the surfaces of CNTs. [18][19][20] For sample B, the C-Ox groups sites can be the suitable places for the adsorption of water, which will react with TiCl 4 for the formation of TiO 2 . And the slow hydrolysis reaction can induce the deposition of TiO 2¯l ms on the surface of CNTs [as illustrated in Fig.…”
