Thermal conductivity enhancement of MWNTs on the PANI/tetradecanol form-stable PCM

We prepared PANI/tetradecanol/MWNTs composites via in-situ polymerization. DSC results indicated that the composites are good form-stable phase change materials (PCMs) with large phase change enthalpy of 115 J g(-1). The MWNTs were randomly dispersed in the composites and significantly enhanced the thermal conductivity of the PCMs from 0.33 to 0.43 W m(-1) K-1. The form-stable PCMs won't liquefy even it is heated at 80 degrees C, so that the MWNTs were fixed in the composite and the phase separation of the MWNTs from PANI/tetradecanol/MWNTs composites won't occur.
