Surfactant effects in functionalized multiwall carbon nanotube-filled phase change materials

Energy storage using phase change materials (PCM) is an efficient way to harness thermal energy from solar energy due to its higher storage density, particularly for medium-temperature applications. However, the PCMs have lower thermal conductivity; owing to this, the thermal performance and heat tr...
