However, the conductivities of P3OT doped with DBSA were found to be low as compared to P3OT doped with [FeCl.
3] where then combined as dopants in a P3OT system.
This is in comparison to a solubility of 0% and 100% for P3OT films doped singly with [FeCl.
Specimen 3 was prepared by using the clear coating B and a base coating B containing a small amount of P3OT (content 0.
Clear coatings A and B, and base coating B containing a small amount of P3OT (content 0.
Figure 4 indicates a typical decay curve of fluorescence from P3OT in the specimen.
The P3OT fractions were dissolved in a solution of 1 wt.
The absorption of dilute P3OT solutions at [Lambda] = 632.
H] was found to be fairly independent of molecular weight, the intrinsic viscosity was determined by measurement of a single concentration for several of the P3OT fractions.
The temperature stability of P3OT was evaluated by TGA in both argon and air, and is shown in Fig.
Initial efforts to characterize P3OT melts were unsuccessful due to rapid crosslinking of the polymer at temperatures above the melting point.
More efficient removal of iron chloride from the P3OT was accomplished by repeated washings with aqueous EDTA solution, resulting in iron levels less than 10 ppm.
