摘要

P(AN-co-VA-co-DEMA) terpolymers were synthesized by aqueous precipitation copolymerization of acrylonitrile (AN), vinyl acetate (VA), and 2-dimethylamino ethyl methacrylate (DEMA) with an Na2S2O5-NaClO3 redox initiating system and fibers from these terpolymers were thus prepared by a wet spinning method. Functionalized multiwalled carbon nanotube (F-MWNT) networks were created on the surface of P(AN-co-VA-co-DEMA) fibers by a simple dipping method. The morphology and interfacial interactions of the obtained F-MWNTs-coated fibers were characterized by scanning electron microscope, Raman spectroscopy, and Fourier transform infrared spectroscopy. The results showed that F-MWNTs were assembled on the fibers and the density of F-MWNTs can be controlled by adjusting the F-MWNTs content in the dipping solution. The assembly process was driven by electrostatic interactions between the negative charges on the nanotube sidewalls and the positive charges of the fibers. The F-MWNTs-coated fibers had a good conductivity. The volume resistivity of the fibers coated with 1.18 wt % F-MWNTs reached 0.27 cm, while the original mechanical properties were preserved.
