“…The second event occurred in the temperature at 348 °C could be attributed to the decomposition of hydrophilic side groups still present in the material, and the third one observed at 497 °C is ascribed to thermal decomposition of 3-MPTMS bonded to carbon sheets, as has been reported in literature for carbon sulfur compounds. 26,42 The lower weight loss of the 3-MPTMS-grafted CB compared to oxidized CB and, as consequence, a higher ceramic yield is most likely due to the formation of SiO 2 during heating, which also confirms the functionalization process.…”

“…In spite of this finding, the silanization reaction is considered successful according to literature data and bearing in mind the CB/3-MPTMS ratio used. 26 Furthermore, the low content of S−H group in the material has been enough for improving the detectability of preconcentration method as will be further demonstrated in the figures of merit.…”

“…36 The broad G' peak (around 2450 cm −1 ) presents in the 3-MPTMS-grafted CB can be assigned to an overtone and is due to D + G phonons contribution and this band shows evidence of the set 3-MPTMS, suggesting that treatment led to higher order. 26 The band around 2330 cm −1 presented in all materials comes from the Raman mode of N 2 gas present in the air surrounding the sample. 44 Thermogravimetric curve (TG) and derivative thermogravimetric curve (DTG) for the CB, oxidized CB and 3-MPTMS-grafted CB are depicted in Figures 5a, 5b and 5c, respectively.…”

“…25 Altering the surface chemistry of CB is sometimes necessary to solve this drawback and also to improve the dispersability, chemical stability as well and the performance to adsorb metals ions. 26 The modification with oxidizing agent provides higher dispersion stability in aqueous medium due to increase of hydrophilic functional groups located at the edges of carbon layer plane such as hydroxyl, carbonyl and carboxyl, which are responsible for surface reactivity of CB. [27][28][29] Silanization is another very popular method to improve dispersion.…”

“…In addition to these elements, CB may contain small amounts of nitrogen and sulfur, depending upon the nature of hydrocarbons used in the manufacture. 22,26 This nanomaterial can be obtained from the partial combustion or thermal decomposition of hydrocarbons. The primary particles of CB exhibits a spherical shape and it presents a strong tendency to agglomerate, because of strong Van der Waals forces among the surface of the CB nanoparticles, affecting their dispersion in polar medium.…”

Carbon black (CB) grafted with 3-mercaptopropyltrimethoxysilane (3-MPTMS) was used as solid phase extractor for Cd 2+ in a flow injection system coupled to flame atomic absorption spectrometry (FAAS). The influence of pH, buffer concentration, preconcentration flow rate and eluent concentration on preconcentration of Cd 2+ were investigated by means of chemometric tools. The characterization of the adsorbent chemically modified was performed by Fourier transform infrared, scanning electron microscopy, energy dispersive X-ray spectroscopy, thermogravimetric analysis, Raman spectroscopy and textural analysis. To perform the on-line preconcentration, 20.0 mL of a pH 7.0 Cd 2+ solution at a flow rate of 4.0 mL min −1 was loaded through 30.0 mg of modified CB and then eluted with 1.0 mol L −1 HCl toward the FAAS instrument. The limits of detection and quantification were found to be 0.20 and 0.66 µg L −1 , respectively. Addition and recovery tests carried out in real samples (mineral, tap and saline waters, and cigarette sample) and the analysis of certified reference material (TORT-2, lobster hepatopancreas reference) attested the applicability of proposed method.

Natural rubber filled with poly(sodium-4-styrenesulfonate) (PSS)-decorated carbon black (CB) by employing a latex compounding technique was prepared. The result of scanning electron microscope demonstrated that CB was uniformly dispersed in the matrix. Comparing to traditional dry compounding, an improvement in physical and mechanical properties was observed in the composites attributed to the homogeneous distribution of CB in matrix and an augment of bound rubber. Owing to the changes of the physical properties of CB surface, vulcanizate filled with oxidized CB via latex way exhibited higher mechanical properties. The resulting vulcanizates displayed a diminished interaction between fillers based on the consequence of strain dependence of storage modulus. Furthermore, a splendid wet-skid resistance was obtained in vulcanizates fabricated by latex compounding technique in comparison with vulcanizates prepared by traditional dry compounding.

Surface modification of carbon black to facilitate suspension polymerization of styrene and carbon black

To carry out suspension polymerization of styrene in the presence of carbon black, an effective method was introduced to modify carbon black using nitric acid for oxygen treatment. The surface modification of carbon black with oxidation was confirmed by Fourier transform infrared spectroscopy, thermogravimetric analysis, and scanning electron microscopy (SEM), which demonstrated that the chemical structure of carbon black has clearly changed. Compared with pristine carbon black (CB), SEM illustrates that the aggregation phenomenon of modified carbon black (MCB) was clearly weakened. After modification, the aggregation and inhibition effects of MCB on the polymerization of polystyrene/modified CB (PS/MCB) composite particles are obviously weakened. The lipophilicity of CB after modification was also increased during the synthesis of PS/MCB. The oxidized CB was successfully dispersed by polystyrene using in situ suspension polymerization. The dispersion and dosage of MCB in PS/MCB composite particles was greatly improved over that of CB in PS/CB composite particles. © 2018 Wiley Periodicals, Inc. J. Appl. Polym.
