Preparation and Performance Analysis of Form-Stable Composite Phase Change Materials with Different EG Particle Sizes and Mass Fractions for Thermal Energy Storage
Abstract:The low thermal conductivity and leakage of paraffin
(PA) limit
its wide application in thermal energy storage. In this study, a series
of form-stable composite phase change materials (CPCMs) composed of
PA, olefin block copolymer (OBC), and expanded graphite (EG) with
different particle sizes (50 mesh, 100 mesh, and 200 mesh) and mass
fractions are prepared by melt blending. OBC as a support material
could reduce PA leakage during melting, and EG as a thermally conductive
filler can improve the thermal perfor… Show more
“…This is because the movement of CA-PA molecules is limited due to the pore size of EVM, and the crystallization behavior of CA-PA is obviously oriented towards (005) crystal plane. [46][47][48] XRD analysis showed that no chemical reaction occurred between CA-PA eutectic and EVM. Moreover, the characteristic diffraction peaks of CA-PA/ EVM-1 and CA-PA/EVM are nearly unchanged aer 100 phase change cycles.…”
