Camphor sulfonic acid doped conducting polyaniline (PANI:CSA) was synthesized by self-stabilized dispersion polymerization (SSDP). Well ordered polymer chains grow at the interface between aqueous and organic phase at low temperature around -35 °C. Thus, the growing polymer chains act as a stabilizer, producing highly conductive polyaniline with low content of structural defect. Moreover, the PANI:CSA thin film exhibits thickness independent conductivity of 550 Scm-1 by adopting Dr. Blade casting method. Using this polyaniline transparent electrode, flexible polymer light-emitting diodes and solar cells were fabricated on flexible PES substrates. The flexible PLEDs show high performance with a luminance of 6000 cdm-2 and a luminous efficiency of 5.6 cdA-1. In addition, flexible PSCs based on composites of poly (3-hexylthiophene) (P3HT) as an electron donor and phenyl-C61-butyric acid methyl ester (PCBM) as an electron acceptor exhibit a reasonable power conversion efficiency of 1.8 %. |
