CNT/Polymer Nanocomposites: A Detailed Review on Mathematical Modeling 209
9.9.1 INTRODUCTION
Polymer fibers are readily produced from the insulating Emeraldine base (EB) (Scheme
1.a) or leucoemeraldine base (LEB) forms of PAni. They are then rendered conductive
by doping using an aqueous acid comprised of small anions [1-6]. The main disadvan-
tage of this approach involves the adverse influence of the acid doping process on me-
chanical properties. Nonhomogenous doping and the possibility of dedoping through
diffusion of small anions from the skin of the fibers cause heterogeneities in the fiber
structure. The doping of PAni in solution, however, results in more homogenous dop-
ing and a more uniform material after casting [7].
The doping of P ...
