摘要：Thermal performance enhanced heat storage nanocomposites consisting of palmitic acid (PA) and multiwalled carbon nanotubes (CNTs) were prepared by dispersing chemically treated CNTs into melting PA. The PA/CNT composites remain stable after repeating energy storage and release 80 times. The melting point and latent heat capacity decrease with an increase in the mass fraction of CNTs. PA/CNT composites have enhanced thermal conductivities compared to pure PA, with the enhancement ratios increasing with the mass fraction of CNTs. For PA/CNT composite containing CNTs with a mass fraction of 5.0%, the thermal conductivity enhancement ratios amount up to 36% and 56% in solid and liquid states, respectively.
