Advantage of the scanning tunnelling microscope in documenting changes in carbon fibre surface morphology brought about by various surface treatments

Comparison of short carbon fibre surface treatments on epoxy composites

“…1(a)) seems to be relatively smooth and there are some small impurities absorbed on the fibre surface, which were introduced during the fibre manufacturing process. Under a treatment temperature of 450°C the surface does not look appreciably different when compared to untreated ones, which suggests that the treatment was mild and did not cause essential morphological changes on the fibre surface [14]. However, by using the gas physical adsorption technique, Wan et al [11] reported that after treatment under a similar condition mentioned above, the total carbon fibre surface area was doubled.…”

EIS study of the redox reaction of at glassy carbon electrode via diazonium reduction in aqueous and acetonitrile solutions

“…Recently, Pinson and Andrieux have demonstrated that the generation of the aryl radical is a concerted process, which involves the electron transfer and the cleavage of dinitrogen before the formation of the covalent bond [3]. This modification process is very attractive because it avoids the use of oxidative conditions which can escort to the damaging oxidation of the carbon substrate [4] and also because it allows the presence of selected functional groups on the aryl groups.…”

Electroanalysis of thiocyanate using a novel glassy carbon electrode modified by aryl radicals and cobalt tetracarboxyphthalocyanine

“…E-mail address: t.nyokong@ru.ac.za (T. Nyokong). of these oxygen functionalized groups has proven problematic to study, aggravated by carbon surface corrosion [12][13][14]. It is consequently necessary to develop convenient and efficient modification techniques for the augmentation of glassy carbon surfaces.…”
