In this research, thermoresponsive and conductive fibers with core-sheath structure were fabricated by coaxial electrospinning. For preparing the spinning sheath solution, poly-(N-isopropylacrylamide-co-N-methylolacrylamide) (PNN) copolymer having thermoresponsive and cross-linkable properties was synthesized by free-radical polymerization using redox initiators; it was then mixed with the conductive poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) at different weight ratios in water. On the other hand, poly(butyl acrylate-co-styrene) (PBS) copolymer synthesized by emulsion polymerization was dissolved in chloroform and used as the spinning core solution. After electrospinning, the fibers were treated at 110 8C for 1 h to cross-link the PNN portion in the sheath for strengthening the fibers. Well-defined core-sheath fibers were observed from SEM pictures; the outside and inside (core) diameters were 568 6 24 and 290 6 40 nm, respectively, as determined from TEM pictures. The fiber mats were further doped by DMSO to enhance their conductivity. For the fiber mat with the weight ratio of PEDOT:PSS/PNN at 0.20 in the sheath, its surface conductivity could reach 29.4 S/ cm. In addition, the fiber mats exhibited thermoresponsive properties that both swelling ratio and electric resistance decreased with temperature. Furthermore, the fiber mats exhibited improved flexibility as evaluated via bending test.

“…Research groups have studied the increase of the water-and weather-stabilities of the conducting polymer with substitution of the PSS polymer chain. 18 In this paper, thermally curable functional groups were incorporated into 4-styrene sulfonic acid sodium salt, to synthesize a thermally curable copolymer, P(SS-co-PEGMA). [13][14][15] The stability of PEDOT with poly(imide) itself and blended with PSS was increased, but the conductivity was under 10 S cm À1 .…”

Synthesis of conductive and transparent PEDOT:P(SS-co-PEGMA) with excellent water-, weather-, and chemical-stabilities for organic solar cells

The water-, weather-and chemical-resistant conductive poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate)-co-poly(ethylene glycol methacrylate) (PEDOT:P(SS-co-PEGMA)) copolymer was successfully synthesized with thermally curable P(SS-co-PEGMA) copolymers. The PSS and P(SS-co-PEGMA) copolymers were synthesized by solution polymerization and PEDOT:PSS and PEDOT:P(SS-co-PEGMA) were synthesized by Fe + -catalyzed oxidative polymerization. PSS and P(SS-co-PEGMA) were characterized by Fourier-transform infrared spectroscopy (FT-IR) and nuclear magnetic resonance spectroscopy (NMR). The electrical properties of the conductive PEDOT:P(SS-co-PEGMA) thin films were characterized in two parts; first, the mechanism and characterization of the conductivity change, and second, the characterization of the water-, chemical-, and weather-stability of the films. The conductivity and transmittance, respectively, of PEDOT:P(SS-co-PEGMA) at 550 nm under optimized conditions were maintained at the levels found in PEDOT:PSS, 160.3 S cm À1 and 86.7%. The introduction of PEGMA to the PSS copolymer improved the mechanical properties and weather stability. The PEDOT:P(SS-co-PEGMA) was highly stable to chemical solvents and independent of the type of solvents used for stability analysis. The conductivity in the weather stability test of PEDOT:PSS decreased by 44.9%, on the other hand, the conductivity of PEDOT:P(SS-co-PEGMA) was decreased by only 22.2%.The PEDOT:PSS and PEDOT:P(SS-co-PEGMA) copolymers were used as buffer layers in organic solar cells (OSC) and showed as high efficiency as conventional PEDOT:PSS materials. The decrease of OSC efficiency with PEDOT:P(SS-co-PEGMA) was 30% less than the OSCs with the commercial and reference PEDOT:PSS buffer layers.

“…The crosslinking methods can generally be divided into two types based on the cross-link bonds. 30 Yin et al 31 synthesized poly(styrene sulfonateco-N-methylol acrylamide):poly(3,4-ethylenedioxythiophene) composites by self cross-linking at different temperature, improving the mechanical property and weather stability compared with commercial PEDOT:PSS. 27 M.
