Abstract Phase change materials have attracted significant attention due to their promising applications in many fields like solar energy and chip cooling. However, they suffer leakage during the phase transition process relatively low thermal conductivity. Here, through introducing hard magnetic particles, we synthesize a kind of magnetically tightened form-stable materials. They achieve multifunctions such as leakage-proof, dynamic assembly, morphological reconfiguration, presenting superior high (increasing 1400–1600%) electrical (>10 4 S/m) conductivity, prominent compressive strength, respectively. Furthermore, free-standing temperature control high-performance electric conversion systems based on these are developed.
