“…Instead of decreasing the thermal conductivity, the CB addition increased the thermal conductivity beyond 20 wt% due to pronounced effect of conductive heat transfer through carbon black particles. It must be noted, CB has been used for both decreasing the thermal conductivity (due to radiative heat absorption) and for increasing the thermal conductivity (due to increased conductive heat transfer) in different composite materials [ 55 , 56 , 57 , 58 , 59 , 61 , 62 ]. The effect of thermal conductivity can change (shape of plot, sharp or slow decline) from experiment to experiment, depending upon the degree of dispersibility, however, the trend (first decrease in thermal conductivity and then increase in thermal conductivity) remains the same.…”

Thermal insulation materials are highly sought after for applications such as building envelopes, refrigerators, cryogenic fuel storage chambers, and water supply piping. However, current insulation materials either do not provide sufficient insulation or are costly. A new class of insulation materials, hollow silica particles, has attracted tremendous attention due to its potential to provide a very high degree of thermal insulation. However, current synthesis strategies provide hollow silica particles at very low yields and at high cost, thus, making the particles unsuitable for real-world applications. In the present work, a synthesis process that produces hollow silica particles at very high yields and at a lower cost is presented. The effect of an infrared heat absorber, carbon black, on the thermal conductivity of hollow silica particles is also investigated and it is inferred that a carbon black–hollow silica particle mixture can be a better insulating material than hollow silica particles alone.

“…The most increases were observed at 90°C 200 bar that the increase was 93% when the amount of acetylene black increased by 40 PHR. Increasing the amount of filler increases thermal conductivity [14,[17][18][19][20]25,26,42,43]. Song et al were worked with acetylene black and reported that thermal conductivity increased as the amount of acetylene black increased [30].…”

“…Many studies have been done to examine the effect of carbon black which is filled into rubber composites as filler on mechanical and conductivity properties [4, 25, 27, 40, 41]. Many studies have found that thermal conductivity increases with the amount of carbon black [14, 17-19, 42, 43]. Many theoretical and empirical models can be used to determine the thermal conductivity of filled polymer composites such as Russell's model, Maxwell-Eucken's model, Bruggeman's model, Fricke's model, Hamilton-Crosser's Model, Nielsen's model, Agari's model, Mixed empirical model, and Percolation model [11].…”

The effects of the amount of acetylene black on viscosity and thermal conductivity and the effects of operating pressure and temperature of capillary rheometer on thermal conductivity were investigated. Five different natural rubber compounds were prepared as 3NAB, 4NAB, 5NAB, 6NAB and 7NAB, which contain different amounts of acetylene black. Thermal conductivities were measured at different temperatures and pressures. The viscosity of the five compounds was measured and it was found that viscosity increases as the amount of acetylene black increases. Thermal conductivity measurements were performed at different temperatures and pressures by using a capillary rheometer. The obtained results indicated that thermal conductivity increased with the increasing acetylene black. The relationship between thermal conductivity-pressure and thermal conductivity-temperature have also been examined. Additionally, the mechanical properties, electrical conductivity, and thermal stability of the compounds were analysed. The change of these properties with the amount of acetylene black was examined.

“…The thermal stability of polymers is of paramount significance due to its critical role in numerous applications. In recent years, the research landscape has expanded to encompass studies concerning the thermal degradation of methacrylate and acrylate main chain polymers bearing distinctly different side groups, further enhancing our understanding of these materials [9][10][11][12][13]. In this study, we synthesized a homopolymer utilizing a monomer derived from a naphthol-containing cinnamic acid derivative and methacryloyl chloride through free radical polymerization techniques.…”

The study investigates the thermal, kinetic, and dielectric properties of a novel methacrylate polymer synthesized from a naphthol-containing cinnamic acid derivative. Notably, the glass transition temperature (Tg) of the polymer, a crucial parameter for amorphous polymers, was found to be significantly higher than traditional methacrylate polymers, owing to the presence of the naphthol group within the polymer structure. The research also delves into the thermal stability and activation energy of the polymer using thermal analysis techniques. Additionally, the dielectric properties of the homopolymer were explored with a focus on the temperature-dependent changes in the dielectric constant and its behavior with varying frequencies.
