摘要：

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.
