Preparation and characterization of carbon black‐polystyrene composite particles by high‐speed homogenization assisted suspension polymerization

Abstract

Composite particles of carbon black-polystyrene with controllable size were successfully prepared using high-speed homogenization-assisted suspension polymerization. The carbon black particles were modified by oleic acid to make it more hydrophobic and more compatible with polymers before the encapsulation process. The effects of homogenization speed, homogenization time, agitation speed, pigment concentration, and stabilizer concentration on the properties of complex spheres were investigated in detail. The results of orthogonal experiments proved that the stabilizer concentration plays the most important role in controlling the size of complex particles. The particles were also characterized by FTIR and SEM. SEM photographs proved that the complex particles had good spherical forms with smooth surfaces.

A cost-effective polyurethane based activated carbon sponge anode for high-performance microbial fuel cells

“…3b) differ signicantly. 36 Aer oxidation, the spectra of the samples included an absorption band at approximately 1700 cm À1 , indicating the formation of surface oxygen complexes C]O stretching vibration. 33,34 An increase in the intensities at 2900 and 2851 cm À1 corresponding to aliphatic C-H bonds, was observed.…”

Titanium dioxide nanoparticles modified three dimensional ordered macroporous carbon for improved energy output in microbial fuel cells

“…The hydroxyl and carboxyl groups were produced after CC decorated with 3DOM-C and TiO 2 /3DOM-C. The peak at 1520 and 1629 cm -1 was the characteristic of -C=C stretching vibration, and the band at 2900 cm -1 was due to the -C-H stretching vibration [29,30]. The bands in the 1000-1450 cm -1 corresponded to C-H stretching and O-H bending vibrations [31].…”

Enhanced thermoelectric performance of highly conductive poly(3,4-ethylenedioxythiophene)/carbon black nanocomposites for energy harvesting

“…4(a), showing the FT-IR spectrum of raw carbon black, displays a large peak in the IR spectrum at approximately 3400 cm À1 . This is attributed to O-H stretching vibrations as a result of the adsorbed water in the carbon surface [17]. A band at approximately 1705 cm À1 and 1300-950 cm À1 indicated C-O structures attributable to the different structural surface oxygen complexes.…”
