摘要: Thermoplastic polyurethane (TPU)/single-walled carbon nanotube (SWCNT) nanocomposite films were prepared using 1,6-hexane diisocyanate and hydroxyl-terminated polybutadiene (HTPB) in tetrahydrofuran with various concentrations of SWCNTs. The interaction between (PU) SWCNTs was studied different methods. film turns yellowish to grayish-black colour upon increasing the concentration PU matrix. This may be due formation π–π amide functional group Differential scanning calorimetric results show that soft segment interacts much stronger than hard segment, which lowering melting transition temperature segments. activation energy thermal stability parameters determined from thermogravimetric differential analyses. x-ray photoelectron spectroscopic intermolecular HTPB-based S...
