【 摘 要 】

A shape-stable phase change material (PCM) compounded through polyethylene glycol (PEG) and triallyl isocyanurate (TAIC) was investigated, in which PEG was used as component of PCM and confined inside cross-linked TAIC. The microstructure of the PEG/TAIC composites was determined by Fourier Transform Infrared Spectroscopy (FT-IR) and X-ray Diffraction (XRD). The results indicated that there was no chemical interaction between PEG and TAIC and the composites remained the PEG crystalline. The size of the composite nanoparticles was about 150 nm. The thermal characteristic of the composites determined by Differential Scanning Caloritheter (DSC) indicated that the composites had excellent thermal stability and heat storage durability after 200 heating-cooling cycles. Moreover, the composites had typical solid solid phase transition temperatures among the range of 31.16-57.14 degrees C and high latent heat enthalpy between 110.2 J/g and 136.9 Ng. The shape analysis suggested that the composites could be used under a high temperature 100 degrees C as thermal energy storage materials. (C) 2017 Elsevier Ltd. All rights reserved.
