“…As shown in Figs 6(a) and (b), the thermal decomposition processes of SR‐0, SR‐0.5 and SR‐10 were almost the same under nitrogen atmosphere. All composites started to decompose at about 410 °C, while the peak values of maximum thermal degradation rate appear at 550 °C as a result of the degradation phenomenon of molecular chain fracture 37,38 . However, their thermal degradation processes were distinguished from each other under air atmosphere.…”

“…As discussed above, BT showed good compatibility and dispersion with a size of 1 to 10 μm. When it was added into the SR composites, it can promote the speed of heat transfer because of the fact that smaller particles can easily occupy the space, increasing the packing density of the composites 39 . The more parts of BT added, the faster was the speed of heat transfer, so the thermal conductivity of the SR composites increases continuously.…”

Silicone rubber (SR)/black titanium (BT) composites with high‐temperature resistance and thermal conduction were prepared via an efficient and convenient blending method. The thermal stability and conductivity of these materials, as well as their properties were systematically investigated to determine the effects of BT. As tensile testing showed, the elongation retention rate of SR‐10 described good antioxidation behavior with a value of 30% after aging at 250 °C for 360 h. Additionally, thermal stability was improved with the introduction of BT. The initial decomposition temperature and maximum degradation rate temperature increased by 200 and 23 °C, respectively, in air atmosphere. As is known, it is difficult for inorganic particles to be well dispersed in a polymeric matrix. However, as observed using scanning electron microscopy, BT displayed a good compatibility and dispersion in the SR matrix without any obvious agglomeration. Moreover, it was found that the addition of BT can further enhance the thermal conductivity of SR to 0.48 W m−1 K−1. © 2021 Society of Industrial Chemistry.
