“…Compared with the weight loss of 3.28% in pristine CSDPF, MCSDPF has more weight loss with 9.48% (curve b) up to 600°C, which is because of the degradation of the silane coupling agent grafting on the surface of CSDPF . These grafting coupling agents are responsible for bridging the CSDPF and rubber tightly together .…”

Synergistic effect of carbon black and carbon-silica dual phase filler in natural rubber matrix

et al. 2013

In this article, the synergistic effects of carbon black (CB) and modified carbon-silica dual phase filler (MCSDPF) on the properties of natural rubber (NR) were investigated. MCSDPF was prepared by modifying carbon-silica dual phase filler (CSDPF) with bis(3-triethoxysilylpropyl)tetrasulphane (Si-69). Fourier transform infrared spectroscopy and thermogravimetric analyzer analyses revealed that Si-69 was successfully grafted to CSDPF. NR-based compounds containing various combinations of MCSDPF and CB were prepared through a mechanical mixing. Investigations of mechanical properties, ageing resistance, abrasion resistance, dynamic mechanical properties, and morphology of tear fractured surface of MCSDPF/CB/NR vulcanizates were conducted. Our study shows that adding MCSDPF led to significant improvement in the tear resistance, fatigue life, and elongation at break of MCSDPF/CB/NR vulcanizates. Optimum stoichiometric combination of MCSDPF and CB inside the NR matrix was derived (ratio of MCSDPF and CB in wt% 5 15/50), which showed synergistic effects of MCSDPF upon CB that was ultimately reflected in their tensile strength, wet skid resistance, and rolling resistance.

“…FB and EFB were synthesized and characterized spectroscopically and by thermal analysis as detailed elsewhere . Hexaammineruthenium(III) chloride, potassium ferricyanide, sodium hexachloroiridate(III) hydrate, dopamine (DA), epinephrine (E), nor‐epinephrine (nor‐E), L‐tyrosine (Tyr), ascorbic acid (AA), uric acid (UA), 4‐acetamidophenol (acetaminophen, Ac), guanine (G), were purchased from Sigma Aldrich (St. Louis, MO).…”

“…Similar conclusions were also observed in the interaction of bromine with fullerenes . FB and EFB were found reactive toward elemental bromine leading to intercalation products involving both chemisorbed and physisorbed bromine . FB doping with bromine is able to introduce rearrangements in the carbon nanomaterial structure leading to a significant overlapping between the fullerene and halogen molecular orbitals and consequently to a reduction in the fullerene band gaps changing their electric/electrochemical conductivity and transport properties of the material (in solid and also in liquid phases, as working medium, useful in electrochemistry).…”

Fullerene Black (FB) and Extracted Fullerene Black (EFB) were used in modified screen‐printed electrodes producing electrochemical transducers (FB‐SPEs and EFB‐SPEs). A complete electrochemical study was performed and the best results are obtained working with FB‐SPEs, especially in terms of: 1. improved electron‐transfer kinetic mechanisms and 2. sensitivity and selectivity toward Acetaminophen (Ac) and Guanine (G). These latter represent two important electro‐active targets to quantify in medicine field application, because: Ac is a preferred alternative (as analgesic‐antipyretic agent) to aspirin, particularly for patients who cannot tolerate aspirin; the oxidation signal of G is useful for the fabrication of emerging analytical tools, such as DNA chipsand user‐friendly diagnostic devices. Ac and G are quantify by using FB‐SPEs electrochemical devices, with an extended linearity (1–300 μM for Ac; 0.1–300 μM for G), an excellent sensitivity (2.82 μA μM−1 cm−2 in the case of Ac; and 0.183 μA μM−1 cm−2 in the case of G), a low detection limit (0.01 μM for Ac; 0.005 μM for G), a very good reproducibility (both: intra‐; inter‐electrodes reproducibility RSD % ranging from 0.3–0.5 for Ac; and 0.50–0.85 for G) and a very fast response time (6 s for Ac; 5 s in the case of G). In addition, high selectivity is obtained at FB‐SPEs, meaning that the FB‐SPEs electrochemical transducers are suitable to simultaneously quantify Ac and G in real samples, having several different (highly concentrated) interference.

“…The bromination may occur as a radical substitution of hydrogen by bromine atoms [9] or as an addition to a carbon-carbon double bond. A recently reported method for bromination of carbon systems is an ultrasound assisted one [10]. The structural properties of carbon-based materials upon bromination are method-and mechanism-dependent.…”

Abstract. An energy dispersive X-Ray study of pure and brominated carbon black was carried out. The analysis of the diffraction patterns reveals that the low bromine load (ca.1% mol) is trapped into the structure, without significantly modifying it. This allows the application of the difference methods, widely tested for electrolyte solutions, inorganic matrices containing metals and isomorphic substitutions.
