Abstract

Highlights: Thermally-induced flexible phase change material is prepared. Bio-based non-polluting 1-Hexadecanol is employed as a phase change component. 1-Hexadecanol has good physicochemical compatibility with Olefin block copolymer. Hexagonal boron nitride contributes to thermal conductivity and leakage-proof. Abstract: High latent heat and thermostatic properties of phase change materials (PCMs) have made them the promising materials. Herein, a novel thermally-induced flexible 1-Hexadecanol/Olefin block copolymer/Hexagonal boron nitride (HD/OBC/h-BN) composite phase change material (CPCM) is proposed. Bio-based non-polluting material of HD is employed innovatively as the phase change component. The triggering of HD phase transition can achieve various deformation modes for CPCM, which is beneficial to reduce the thermal contact resistance between CPCM and device. The electrically insulating property of h-BN not only improves the thermal conductivity and the heating/cooling rate of CPCM, but also further solves the problem of the HD leakage (as low as 0.31 wt%). The prepared CPCM with excellent flexibility and high latent heat (above 150 J/g) has good thermal stability and thermal reliability in the working temperature range. This provides developed CPCM greater potential for thermal energy storage (TES) and thermal management (TM) than conventional PCMs.
