Copper nanoparticle/paraffin composite emulsions (CPC) was prepared by using phase transition emulsification method, in which the paraffin and copper nanoparticles are used as a dispersion medium and heat medium, respectively. The performances of stability, rheology, thermal conductivity, and thermal cycling stability of CPC are studied. The results show that the density, viscosity and thermal conductivity of CPC are increased with the increase of mass fraction of copper nanoparticles. Meanwhile, the density change is negligible, and the thermal conductivity is increased significantly with a large enhancement of 161.96% with a small mass fraction of 0.05 wt%. Since enhancement of the thermal conductivity, the phase change platform of nano-Cu/paraffin emulsion in the solid-liquid phase is not obvious during thermal cycling, but the thermal cycling stability is very good.
