Development　of　low-cost　equipment　that　can　store　clean　energy,　such　as　solar　energy,　is　effective　for　alleviating　environmental　pollution.　In　this　study,　the　shape-stabilized　composite　phase　change　materials　(PCMs)　based　on　paraffin　wax　and　carbon　foam　were　prepared.　The　carbon　foam　prepared　from　melamine　foam　had　a　good　pore　structure　and　was　used　to　encapsulate　paraffin　wax.　The　latent　heat　of　melting　and　cooling　of　composite　PCMs　were　221.1　J/g　and　213.7　J/g,　respectively.　Even　after　100　cycles,　it　still　showed　good　thermal　performance.　Meanwhile,　the　composite　PCMs　exhibited　good　light-to-heat　conversion　efficiencies　of　53.94%　and　67.43%　at　light　intensities　of　200　mW　cm(-2)　and　300　mW　cm(-2),　respectively.　Overall,　composite　PCMs　with　excellent　thermal　performance　and　cycle　stability　have　application　prospects　in　industries　such　as　construction,　solar　energy,　and　battery　temperature-control　systems.
