Electrical properties and stability of epoxy reinforced carbon black composites

Influence of irradiation crosslinking on time dependences of conduction and self‐heating in acetylene carbon black filled high‐density polyethylene composites

“…During the process of self-heating, the decay in I(t) and the increase in T s (t) could be described as 13,28,29 I͑t͒ Ϫ I e ϭ ͑I 0 Ϫ I e )exp͕ Ϫ t/ i ͖…”

Comparative studies on Graphite and Carbon Black powders, and their dispersions

“…8 The characteristic XRD patterns of these powders were recorded using an Xpert' PRO XRD spectrometer, equipped with Cu anode X-ray tube (with K α radiation of 1.54 Å), a flat crystal monochromator, and a proportional detector consisting of a cylindrical chamber filled with xenon/methane gas mixture. UV-Vis optical studies of the prepared samples of CBMF, 9 GMF, 10 CBSO 11 and GSO 12 were investigated using Lambda 35 Double Beam UV-Vis Spectrophotometer, manufactured by Perkin Elmer, Germany.…”

“…The diverse nature of surface and dispersion properties of different grades of CB has immense impact on their realization in xerographic toners [7]. In addition to this, CB is used in the tire industry as reinforcement filler [8] as well as pigment for printing inks, plastics and coatings [9,10]. CB is known to possess high refractive index (n = 2.26) with good chemical and thermal stability [11].…”

Influence of dispersing additives on the conductivity of carbon black pigment dispersion

“…(2) The peak at 1600 cm À1 originates in asymmetrical stretching of aromatic C=C bond with the oxygen atom near one of the vibrating C atoms. (3) The broadest peak at about 1250 cm À1 could be attributed to different functional groups such as the C-C and C-O-C stretching and the C-H deformation of the aromatic hydroxyl unit that is hydrogen-bonded to the conjugated carbonyl group. [27][28][29] The carbonyl peak does not appear in the spectrum of XE2-B powder; moreover, the other two peaks are smaller, indicating lesser oxygen content and a higher tendency to its random bonding on the surface of the XE2-B powder.…”

“…1 It is used to modify the mechanical, electrical, and optical properties of the bulk medium, enabling such materials to be used in widespread industrial applications, such as mechanically reinforced plastic, 1 abrasively improved rubber, conductive composites, [2][3][4][5][6] pigmented inks, and other coating formulations. 7-10 CB is also used for the adsorption of molecules from air or from aqueous media.…”
