Future potential for lithium-sulfur batteries
2023, Journal of Power SourcesThe influence of physicochemical properties on the processibility of conducting polymers: A bioelectronics perspective
2022, Acta BiomaterialiaCitation Excerpt :Thiéblemont et al. [77] demonstrated that the stability of chemically synthesized PPy films in an inert atmosphere could be increased by changing the sulfonate dopant used for synthesis, from classic pTs to naphthalenesulfonates. It should also be noted that the conductivity of PPy films increased by exposing them to moisture in the first few days [78]. It is believed that a slight exchange of the original dopant with ambient oxygen is the reason for this observed phenomena [77] Kanwat et al. [79] demonstrated a similar effect of dopant counterions within a PEDOT:PSS system.
Electrolyte and solvent effects in PPy/DBS linear actuators
2015, Sensors and Actuators, B: ChemicalCitation Excerpt :To have movement of only one ion type (anions or cations with solvent molecules) at anodic or cathodic potentials to dominate the actuation has been a major goal in the development of CP actuators. Synthesis temperature, electrolyte, polymerization conditions (i.e. galvanostatic, potentiostatic and potentiodynamic) and different solvents [14–16] have been investigated. However, the reasons why on occasions anion, cation or mixed-ion actuation occurs are not fully understood.
Transparent electrodes based on conducting polymers for display applications
2013, DisplaysCitation Excerpt :Conducting polymers adopting extended conformation tend to have higher conductivity. It has been shown that (i) the conductivity of stretched free-standing conducting polymer thin films were greater than that of the original unstretched films and (ii) the conductivity of the stretched films parallel to the stretching direction was higher than the conductivity of the stretched films perpendicular to the stretching direction [141–144]. Higher degree of crystallinity was found in stretched free-standing conducting polymer thin films with higher conductivity [144].
Effect of structural anisotropy on electrical and magnetic properties of polyaniline conducting films
2013, Synthetic MetalsCitation Excerpt :Accordingly, all the studies published until now have been concerned with the in-plane structural and electrical anisotropies of films and have compared the in-plane conductivities measured along and perpendicularly to the polymer chains orientation direction. In such conditions, the highest reported anisotropy ratios of the electrical conductivity were typically ranging in between 100 and 250 at room temperature [2–8]. It has been estimated that by ordering, perpendicular bandwidths at the valence band can be noticeably increased of typically 0.2 to 0.3 eV above their otherwise typical values in disordered systems (around 0.45 eV in general) [9,10].
