To extend the applications of phase-change materials to multiple scenarios, Fe 3 O 4 nanoparticles were deposited on the surface of mica with a layer-like structure using a simple method, and composite phase-change materials (CPCMs) with dual-driven energy conversion performance were subsequently obtained via vacuum impregnation. The addition of boron nitride (BN) and cellulose nanofibers (CNFs) endowed the CPCMs with higher thermal conductivity (0.85 W m −1 K −1 ) and lower specific heat capacity (1.42 MJ m −2 K −1 ), thereby constructing ...
