For　enhancing　the　heat　storage　and　encapsulation　performances　of　organic　phase　change　materials　(PCMs),　a　carbon　foam　(CF)　with　a　continuous　dual-scale　pore　structure　(DCF)　was　developed.　Employing　the　as-prepared　DCF　as　a　stearic　acid　(SA)　support,　a　novel　shape-stabilized　SA-CF　composite　PCM　with　a　continuous　dual-scale　interpenetrating　network　structure　was　achieved　through　the　impregnation　of　SA　into　the　DCF.　DCF-900,　prepared　at　an　activation　temperature　of　900　°C,　possesses　a　high　loading　capacity　of　89.54　wt　%　for　melted　SA　without　leakage.　The　resulting　SA/DCF-900　composite　with　a　continuous　dual-scale　interpenetrating　network　structure　exhibits　excellent　comprehensive　performances　with　a　good　synergistic　effect.　The　composite　presents　a　thermal　conductivity　of　1.298　W/m·K　and　an　encouraging　compressive　strength　of　9.03　MPa,　which　increase　by　2.25-fold　and　3.56-fold　compared　with　those　of　DCF-900,　respectively.　Furthermore,　its　melting　and　freezing　enthalpies　reach　192.8　and　192.7　J/g　with　a　storage　efficiency　of　about　100%,　respectively;　meanwhile,　it　displays　excellent　thermal　cycle　stability　and　reversibility　after　600　thermal　cycles　with　a　high　melting/freezing　enthalpy　retention　rate　of　up　to　96%.　More　importantly,　its　light-to-thermal　conversion　efficiency　reaches　91.8%　under　a　light　intensity　of　100　mW/cm2.　Consequently,　the　SA/DCF-900　composite　is　a　promising　candidate　for　high-performance　PCMs.　©　2022　American　Chemical　Society.
