Preparation and characterization of poly(diethylene glycol hexadecyl ether acrylate)/graphene oxide composite shape-stabilized phase change materials
摘要
Abstract
Poly (diethylene glycol hexadecyl ether acrylate)/graphene oxide (PC16E2AC/GO) composite-shape stabilized phase change materials was prepared by the solution blending method. The morphology and structure, phase change behavior and thermal stability of PC16E2AC/GO were characterized by scanning electron microscope (SEM), differential scanning calorimetry (DSC) and thermal gravimetric analysis (TG). The results show that the addition of GO can significantly improve the shape stability of PC16E2AC. When the content of GO is 5%, the PC16E2AC/GO composite material has high heat enthalpy, good thermal stability and thermal stability. The composite phase change materials with 5%GO appears can maintain a good shape above the melting temperature of PC16E2AC and no leakage of PC16E2AC appears after 100 min treatment at 85℃. In addition, good thermal cycling stability is possessed which is approved by 300 times of hot and cold cycle tests.关键词
