Abstract:

Electrospun polyacrylonitrile/boron nitride (PAN/BN) composite nanofibrous membranes with different mass ratios were used as supporting materials to overcome the problems of poor thermal conductivity and the leakage problems of capric acid-palmitic acid-stearic acid (CA-PA-SA) ternary eutectic acting as solid-liquid phase change materials. And then innovative CA-PA-SA/PAN/BN composite phase change fibrous membranes were prepared by physical adsorption. The influences of BN nanoparticles with high thermal conductivity on their morphological structure, thermal performance, as well as thermal energy storage and release rates were studied. The scanning electron microscopy images reveals that the morphological structure of CA-PA-SA/PAN/BN composite phase change fibrous membranes are unaffected by the addition of 10 % BN nanoparticles. The differential scanning calorimetry results suggest that the melting temperatures and enthalpies of the prepared composite phase change fibrous membranes are about 25 ℃ and 136.4-138.6 kJ/kg, respectively. Heat transfer test results indicate that the integral heat transfer performance of CA-PA-SA/PAN/BN composite phase change fibrous membranes are improved by virtue of the addition of BN nanoparticles with high thermal conductivity, and their melting and freezing times are shortened about 38% and 41%, respectively.

Key words: composite phase change fibrous membrane, boron nitride, capric acid-palmitic acid-stearic acid ternary eutectic, thermal energy storage property, heat transfer property
