Herein, the preparation and characterization of homogeneous nanoparticle enhanced phase change material (PCM) is presented. Sp07/sp11 PCMs suitable for winter climate conditions are mixed with 0.5-5.0 wt. % of CuO/Al2O3 nanoparticles (NPs). Results indicate that stable PCM-nanoparticles composites are produced without altering the base material's chemical structure and crystalline nature. The produced composites do not sediment even after multiple thermal cycles. The materials have slightly increased densities and improved viscosity. The complete melting time reduces by similar to 34.8 % for 5.0 wt. %CuOsp07 and similar to 20.7 % for 5.0 wt. %Al(2)O(3)sp11 compared to base PCMs. Using 5.0 wt. % CuO nanoparticles with sp11 improves its pH by 0.34. A 0.25 wt. %CuOsp11 sample's latent heat is deteriorated by similar to 7.3 % when composition rises to 5.0 wt. %CuO.
