摘要
The electrical conductivity of polyaniline doped with camphor sulfonic acid (PAn\|CSA) was studied. The results indicate that there is a critical temperature (\%T\%\-c) and the temperature dependence of PAn\|CSA conductivity shows metallic and semiconductor characteristics above and below \%T\%\-c, respectively. The higher the molecular weight of PAn, the lower the \%T\%\-c. The conductivity was enhanced remarkably when PAn\|CSA film was stretched, its room temperature conductivity is up to 750 S/cm when elogonation is 60%; however, \%T\%\-c was independent of elongation.
The electrical conductivity of polyaniline doped with camphor sulfonic acid (PAn-CSA) was studied. The results indicate that there is a critical temperature (T c ) and the temperature dependence of PAn-CSA conductivity shows metallic and semiconductor characteristics above and belowT c , respectively. The higher the molecular weight of PAn, the lower theT c . The conductivity was enhanced remarkably when PAn-CSA film was stretched, its room temperature conductivity is up to 750 S/cm when elogonation is 60%; however,T c was independent of elongation.
