Abstract To address the limitations of conventional energy systems and optimize conversion pathways efficiency, a type “five-in-one” multifunctional phase-change composite with magnetothermal, electrothermal, solar-thermal, thermoelectric electromagnetic shielding functions is developed for multipurpose applications. Such novel fabricated by an innovative combination paraffin wax (PW) as material carbonized polyimide/Kevlar/graphene oxide@ZIF-67 complex aerogel supporting material. The exhibits unique bidirectional porous structure high porosity robust skeleton to support loading PW. reduced graphene oxide CoNC resulting from high-temperature carbonization are anchored on generate thermal conduction magnetic effect, enhancing phonon electron transfer improving its efficiency. not only excellent thermoelectric, magnetothermal performance, but also achieves interference effectiveness 66.2 dB in X -band. introduction PW significantly improves energy-storage capacity during multi-energy conversion. great application potential efficient solar utilization, sustainable power generation, outdoor deicing, human therapy, electronic device protection.
