As shown, functionalization of MWCNTs with electrically conductive compound (P3OT) favours development of electrically conductive network within insulating polymer matrix, especially at higher nanofiller contents.
It has also been shown that modification of EOC17 with P3OT functionalized MWCNTs ensures simultaneously high values of stress at break [[sigma].sub.b] and strain at break [[epsilon].sub.b] even at high nanofiller content (10 wt%), which are 2.5 and 3.5 times higher, respectively than the values determined for systems containing pristine MWCNTs.

A number of functionalized sulfonic acids were studied to determine if these types of acids would also be applicable as dopants for P3OT. Of those studied, only DBSA showed further feasibility due to the spectral change and conductivity increase observed upon addition to a P3OT solution .
However, the conductivities of P3OT doped with DBSA were found to be low as compared to P3OT doped with [FeCl.sub.3] as seen in Fig.
DBSA and [FeCl.sub.3] where then combined as dopants in a P3OT system.
Specimen 2 was prepared by using a clear coating B containing 0.05wt% of P3OT and the base coating B.
Specimen 3 was prepared by using the clear coating B and a base coating B containing a small amount of P3OT (content 0.05wt%).
The P3OT fractions were dissolved in a solution of 1 wt.% tetrabutylammonium p-toluenesulfonate (TBATS, Aldrich) in THF (Fisher OPTIMA grade).
The absorption of dilute P3OT solutions at [Lambda] = 632.8 nm was measured on Perkin-Elmer Lambda 5 UV-VIS spectrophotometer and found to obey Beers' at the dilute concentrations studied ([less than] 10 g/L).
Many of the P3OT samples contained significant amounts of iron chloride remaining after their synthesis.
The temperature stability of P3OT was evaluated by TGA in both argon and air, and is shown in Fig.
