Figure 4. SEM images of PEDOT coated and soak tested fibers.

Figure 4

(a) SEM image of a PEDOT:pTS coated carbon fiber aged to simulated day 172.2 showing PEDOT still at the tip, but with a possible void or loss of PEDOT:pTS in the center. (b) SEM image of a PEDOT:PSS coated carbon fiber aged to simulated day 172.2 showing similar properties to that of the PEDOT:pTS coated fiber.
