摘要

A biodegradable polyurethane (PU)/carbon nanotube (CNT) composite was prepared by bulk polymerization based on in situ cross-linking of hydroxyl-terminated polylactic acid functionalized CNTs. As parallel experiments, PU/CNT blend and pure PU were prepared. The obtained products were characterized by Fourier transform infrared (FTIR), thermogravimetric analyses (TGA) and differential scanning calorimetry (DSC), hydrogen nuclear magnetic resonance (1{sup left}H NMR) and field emission scanning electron microscopy (FESEM). The properties and morphology of composites were discussed including both blending and cross-linking composites. The results showed that the functionalized CNTs were dispersed well in the PU matrix, and its initial thermal decomposition temperature was higher than that of the blend.
