“…The peak at 284.6 eV is the contribution of CeC in aliphatic and aromatic species in the material [25], which implies that carbon has been formed possibly due to the dehydration during the combustion. A binding energy of 285.4 eV can be attributed to CeOH, CeOP, or CeN [26]. A binding energy of 287.1 eV can be assigned to eC]O [26].…”

“…Nakayama et al analyzed carbon fibers, on which various oxygen-related surface functional groups coexisted, by combining the GCD method with the curve-fitting method. [39] Chilkoti and Ratner considered the selectivity of several derivatization reagents for the OH and COC groups in the corresponding polymer films and exploited the more suitable reactions. [44] Malitesta et al considered the C O and C N groups in polypyrrole films.…”

“…[33,34] Thus the reactions have been performed in the gas phase, which is designated as the gas-phase chemical derivatization (GCD) method. [31,35 -38] Its systematic analysis was established by Nakayama, Takahagi, and co-workers, [38] and has been applied to the surface analyses of carbon fibers [39,40] DLC films, [41] and other carbonaceous materials. [42,43] However, the GCD method has a serious drawback that a derivatization reaction does not always concern the target surface functional group but is also sensitive to other groups.…”

a Oxygen-related surface functional groups on diamond-like carbon (DLC) films were derivatized with fluorine-and nitrogenrelated groups by the gas-phase chemical derivatization (GCD) method, and the groups were analyzed quantitatively by X-ray photoelectron spectroscopy (XPS). It is desirable that a derivatization reaction is unique to the target group; however, it usually causes undesirable side reactions which affect other groups. This diversity of the reactions has complicated the analysis. In this report, we have overcome the problem by applying a mathematical treatment which takes the side reactions into account. This improved analysis shows that it is no longer necessary to have derivatization reactions unique to the target groups. As a result, it is demonstrated that the carbonyl (C O) group is the dominant surface functional group on both the DLC and its wet-oxidized films, the carboxyl (COOH) group plays a minor role, and the presence of the hydroxyl (OH) group is logically denied. Considering the oxidation steps of these oxygen-related surface functional groups, it is suggested that the C O group on the DLC films requires the cleavage of the carbon-carbon bond with a relatively high activation energy barrier to change into the COOH group.

“…By this process, relative intensity Fls/Ois will become less than that of (1) because of the washing out of the low molecular compounds from the surface layer. The de rivatization in gas phase were undertaken by the simi lar method to Nakayama's methods (8)(9)(10). The adopted method was shown in Fig.…”
