基于Pickering乳液法的石墨烯/PCM复合材料的制备与性能
Preparation and properties of graphene/PCM composites based on Pickering emulsion method
摘要
Abstract
As a typical phase change material(PCM)for energy storage,paraffin(PA)was found to possess shortcomings such as easy leakage and poor thermal conductivity,which had limited its large-scale market applica-tion.To address this issue,solidified paraffin/graphene(PaGr)composites were prepared by a one-step hydrother-mal method,in which PA served as the matrix phase change material and reduced graphene oxide(RGO)acted as the confining carrier.During the hydrothermal process,the Pickering emulsion,configured with GO as a stabilizer,facilitated the effective recombination of paraffin and graphene.XPS and Raman spectroscopy were employed to con-firm the successful conversion of GO into RGO during the hydrothermal reduction process.The microstructure,ther-mophysical properties,and structural stability of the PaGr composite PCM were characterized through optical mi-croscopy,DSC,and thermal cycling.The experimental results show that PaGr composites can effectively improve the shape instability and high thermal resistance caused by PA liquid leakage.Compared with pure PA,its thermal conductivity and structural stability are improved,which indicates that PaGr composites have broad application pros-pects in the field of PCM.关键词
