“…The phase separation of SAT was significantly suppressed by the introduction of carboxymethyl cellulose (CMC) and urea . In contrast, expanded graphite (EG), a carbon-based material, can effectively improve the thermal conductivity of SAT and its thermal reliability for long-term applications. − Meanwhile, in our previous work, the supercooling of the composite (labeled as SEBC) was reduced to 1 °C, and thermal conductivity was increased to 2.326 W·m –1 ·K –1 by adding 1 wt % borax, 4 wt % EG, and 2 wt % CMC to SAT, and no phase separation occurred during the phase transition . However, the composites obtained through these methods tend to have the disadvantages of irrecoverable fractures and poor flexibility .…”
