摘要：

The present work aims to study the preparation and thermal energy storage behavior of CuO based composite PCM for thermal energy storage. Composite PCM comprises palmitic acid as base material and CuO nanoparticles (NPs) as supporting materials. Different mass fractions of NPs have been dispersed in the base material so as to determine the maximum thermal conductivity enhancement. SDBS has been selected as the surfactant for ensuring the uniform dispersion of NPs in base material. With the help of DSC measurements, the newly prepared composite PCMs have been tested to determine their phase change temperatures as well as latent heats during melting and solidification. Thermal conductivities of the composite PCMs with all mass fractions of NPs have been measured. Based on the test results, the newly prepared composite PCM could be considered to be a potential candidate for thermal energy storage. (C) 2017 Elsevier Ltd. All rights reserved.
