Formation of functional groups on graphite during oxygen plasma treatment

Oxygen plasma functionalization of poly(p-phenilene sulphide)

“…Plasma treatment was performed in a plasma reactor that consisted of a discharge vessel, a two-stage rotary vacuum pump, a gas feeding system, vacuum gauge, and a rf generator [11]. The discharge vessel is a cylinder with the length of 400 mm and the diameter of 40 mm, made from a borosilicate glass with a low recombination coefficient for reaction O + O !…”

A comparison between physically and chemically driven etching in the oxidation of graphite surfaces

“…as catalyst supports [1], biomedical materials [2], or first-wall materials in nuclear reactors [3]. Depending on the specific use the carbon material will be given, different surface characteristics (for example, nanostructure or chemical composition) must be tuned to different levels in order to modulate such properties as adhesion [4,5], wettability [6], or adsorption [7]. This implies that several different methods for the controlled modification of carbon surfaces must be available, as well as an in-depth understanding of their effects on carbon surfaces at the microscopic level.…”

“…As a particularly relevant type of surface modification of carbon materials, we concentrate here on oxidation. Oxidation of carbon materials is a topic of scientific and technological relevance [6,[8][9][10][11][12][13], and can be carried out through a variety of approaches. Thus, carbon surfaces can be oxidized via high temperature treatment under air or molecular oxygen [9,14], through oxygen ion bombardment [15][16][17][18], by exposure to oxygen-containing plasmas [10,11,19,20] or ozone [21,22], or by wet chemical and electrochemical means [23].…”

Density of O-atoms in an Afterglow Reactor During Treatment of Wool

“…The initial step in interaction is surface functionalization. Oxygen radicals interact chemically with the surface of organic materials causing formation of O-rich polar functional groups such as C-O, C=O, O-C=O [9]. After receiving a certain dose of radicals the surface of an organic material becomes saturated with oxygen.…”
