Abstract
ABSTRACT Achieving efficient thermal management in high‐power and flexible electronic devices remains a major challenge, particularly in the development of polymer‐based phase change materials (PPCMs). Here, we report a PPCMs constructed by embedding covalently bonded boron nitride/carbon nanotubes (BN/CNTs) hybrids into a paraffin wax/ polydimethylsiloxane (PW/PDMS) matrix, which is called PW/PDMS@BN/CNTs (PPBC). The hybrids were synthesized through dopamine‐assisted polymerization and amidation between amino‐functionalized BN and carboxylated CNTs, forming continuous, chemically connected heat transfer networks. Structural analyses confirm stable amide linkages and homogeneous dispersion of fillers. The…
