Fabrication and characterization of small organic molecules/expansion graphite composite phase change materials
摘要
Abstract
The phase change materials of small organic molecules as functional materials are loaded to vermicular slit porous expansion graphite carrier through the vacuum-load method,and the composite phase change materials with good phase change performance and stable mechanical properties are prepared.Wide-angle X-ray diffraction (XRD) measurements,differential scanning calorimeter (DSC),field emission scanning electron microscope (FE-SEM) and transmission electron microscope (TEM) were employed respectively to investigate their structure,thermal properties and load effect.The results show that with the help of the nanoscale slit confinement effect of the expanded graphite as well as heterogeneous nucleation of composite phase change materials after loaded process in expanded graphite,small organic molecule phase change units keep the structural stability,and lattice structure become more regular and the crystallinity increased obviously.The whole of the composite phase change materials show excellent phase transformation function.The supercooling phenomenon of phase change process is also significantly improved.关键词
