Preparation of High Heat Absorption Polyethylene Terephthalate

The modified nanohigh heat absorption agent carbon black(CB) was added to the polyethylene terephthalate(PET) and the PET-CB nanocomposite material was prepared through in situ polymerization. The structure and performance of PETCB nanocomposite material were analyzed and characterized through differential scanning calorimeter (DSC), thermal weight analysis (TGA), polarization microscope (POM), scanning electron microscope (SEM), infrared spectrometer, etc. Results show that nanohigh heat absorption agent carbon black disperses well in PET. The decomposition temperature of PET-CB nanohigh heatabsorbing composite material is 1.08 °C higher than that of pure PET. The heat absorbing performance of PET-CB nanocomposite material is good, which can save energy effectively.
