Abstract

Single-walled carbon nanotubes/poly(p-phenylene benzobisoxazole) (PBO/SWNT) composite fibers were prepared by in situ polymerization and dry-jet wet spinning. PBO/SWNT composite fibers were characterized by Raman spectroscopy, scanning electron microscope, TG-DTG analyses and so on. Furthermore, the thermal resistance and tensile strength of SWNT and PBO/SWNT were characterized. The results showed that SWNT contained many carboxyl and hydroxyl groups after acid treatment. The thermal resistance of the PBO/SWNT fibers was higher than PBO and the tensile strength was also improved by 20-50%.
