Abstract: | In this research article, we have described the synthesis of acid (HCl)-doped poly(anthranilic acid) (PAA) with carboxylic
groups containing multi-walled carbon nanotubes (c-MWNTs) via in situ polymerization. Anthranilic acid monomers were adsorbed
on the surface of MWNTs and polymerized to form PAA/c-MWNT composites. The structure of PAA/c-MWNT composites was characterized
by UV–vis spectra, Fourier transform infrared spectroscopy, nuclear magnetic resonance, and X-ray diffraction patterns. Scanning
electron microscopy and transmission electron microscopy images showed that both the thinner fibrous phase and the larger
block phase could be observed. The individual fibrous phases had diameters of about 100 nm, and therefore, must be the carbon
nanotubes (diameter 10–20 nm) coated by a PAA layer. The electrical conductivities of PAA/c-MWNT increased with the increase
of c-MWNT content. |
