Abstract |
Phase change materials (PCMs) possess very high heat storage capacity and are capable of maintaining a
constant temperature during phase change, which makes them most prominent candidates for solar
energy storage systems, heating, and cooling systems. The low thermal conductivity of PCM results in
slow heat transfer and low heat storage and release rate, which is a major drawback for their practical
applications. This review focuses on the enhancement of thermal conductivity by the introduction of
highly thermally conductive metallic and carbon-based nanoparticles, metallic foams, expanded graphite
and encapsulation of PCM. Carbon-based nanoparticles including carbon fiber, carbon nanotubes, and graphene show better performance than metal-based nanoparticles due to lower density and better dispersion. The thermal conductivity of the composite phase change material (CPCM) depends on the shape, size, aspect ratio and concentration of nanoparticles. The thermal conductivity of CPCM increa
