Abstract
Polyaniline, poly(aniline-co-o-aminobenzyl alcohol), and poly(o-aminobenzyl alcohol) have been synthesized and characterized by a number of techniques including X-ray photoelectron spectroscopy (XPS), 1H nuclear magnetic resonance spectroscopy (1H NMR), thermogravimetry (TG), differential scanning calorimetry (DSC), and ultraviolet-visible absorption spectroscopy (UV-vis). Conductivities of the HCl-doped polymer ranged from 101 S cm-l for polyaniline to 10-3 S cm-l for poly(o-aminobenzyl alcohol). Copolymer composition show that aniline and o-aminobenzyl alcohol have similar reactivities. The substituted polymers exhibited enhanced thermal stability and hydrogen-bonding interactions. The results were rationalized based on the effect of the -CH2OH substituent on the polymer structure.
