“…We have reported that the agglomerates of CB could be broken down into smaller aggregates under the intensive action of powerful shear force [33][34][35][36]. In this case, a similar situation occurred under strong shear force above 280°C in HAAKE rheometer, resulting in easier absorption of melted NASS monomer (melting point 300°C) on the larger surface of CBs.…”

“…The chains grew on the surface of CBs to form PNASS encapsulated carbon particles. Finally, the produced polymer chain radicals could be terminated either by other chain radicals or carbon surface as a strong radical scavenger because of its polycondensed aromatic rings [33].…”

“…Concerning our previous work, we find an effective thermo-mechanical method, facile and practical in carbon modifying. The really nanoscale dispersed CB particles are prepared in solid state under powerful shearing force and high temperature by blending a hinder phenyl antioxidant small molecules [33,34] (Irganox 1330, LA-57, or AO-80) and CB particles in an internal mixer. Secondly, decomposed natural rubber chains have been successfully grafted onto surface of CB particles by the same method [35].…”

“…The difference between the particle size of CB and m-CB indicates that m-CB aggregates were partially broken and the added organic molecular layer formed on the m-CB surface protected the CB from reaggregating, as discussed in our former work. [14] Although the original CB existed in the form of smaller aggregates in the liquid acrylic resin dispersions, once the dispersions were vacuum dried, the morphology of the CB varied significantly, as shown in Fig. 3(a).…”

To improve the dispersion stability of carbon black (CB) in an acrylic resin coating, a hindered phenolic antioxidant (AO80) was chosen to modify the CB by a solid state method based on the blending of CB and AO80 in an internal mixer. The modified CB (m-CB) was directly introduced into the acrylic resin with 50% solid content in butyl acetate by ball milling without any other treatment. That the majority of the m-CB particles were nanosized in ethanol was proven by a particle size analyzer. Transmission electron microscopy (TEM) and field emission scanning electron microscope (FESEM) micrographs indicated that the m-CB particles were also dispersed in the acrylic resin as nanoscale particles. Compared with the unmodified CB, the modification of CB can decrease the viscosity of the acrylic resin/m-CB nanocomposite and improve its flow property. The adhesion and gloss of the acrylic resin/m-CB nanocomposite were also improved. More importantly, the UV shielding and stability of the acrylic resin/m-CB nanocomposite were enhanced.

“…To obtain carbonic nanomaterials with better mechanical properties, it is essential to strengthen the mechanical and chemical combination of the materials by dispersing nano materials evenly on the matrix resin. The strength of the combination of materials can be measured with tensile and bending tests, and their morphology can be evaluated by using transmission electron microscopy (TEM) [11,12].…”

This article describes an evaluation of the mechanical properties and sound insulation effects of composites made of acrylonitrile butadiene styrene (ABS) and carbon-black using the design of experiment (DOE) approach. The solution blending process and method are presented. The effect of the acetone content in ABS during the drying process was studied by conducting tensile tests of injection-molded specimens. ABS was dissolved in acetone, and carbon-black was dispersed in the ABS/acetone mixture with varying conditions according to the orthogonal array table used to reduce similar experiments. The tensile specimens were produced by injection molding in each of the DOE cases, and the elastic modulus and maximum tensile strength of ABS/carbon-black composites were evaluated with a tensile test to determine the main effects of those factors. A sound insulation test was conducted with a modified impedance tube by using the DOE orthogonal array table, and a correlation between carbon-black and the sound insulation was revealed by a main effect analysis. An additional sound insulation test was conducted to verify the sound insulation effect of ABS/carbon-black composites as a function of the carbon-black percentage. The results indicate that the increase of carbon-black affected the mechanical properties as well as the sound insulation effects of ABS/carbon-black composite.
