Regioregular Poly

ABSTRACTWe demonstrate that charge-transport in partially-ordered thin films of poly(3- hexylthiophene) is strongly dependent on the charge-carrier density in the film, which we relate to the localized nature of the charge carriers. We base our conclusions on measurements in which the charge-carrier density is varied by electrostatic means (in a transistor geometry) and by in- situ thermal removal of oxygen dopants. For the doping levels investigated, we argue that the removal of oxygen does not induce structural changes in the conjugated polymer, and that it only shifts the Fermi-level of the film.

Abstract This work presents a triboelectric nanogenerator (TENG) fabrication using polytetrafluoroethylene, aluminum foil, and cellulose paper. Mechanical interactions lead to atomic defects that stimuli the delocalized electrostatic charge carriers and kinetic energy. The addition of ionic salt’s microdroplets improved the TENG’s performance. Eventually, surface charge activities have escalated the electrical signals. Further, studied spontaneously increased charge transport performance at the steady-state condition in the presence of NaCl ionic droplets. We considered that these ionic activities actively participated in detecting salt ions.

Intimate Contact

ABSTRACTRecently, there has been considerable interest in advanced materials and processing techniques for practical applications. V2O5 xerogels have generated much attention because they are layered materials that undergo reversible redox intercalation with lithium. The sol-gel process has been used to intercalate V2O5 xerogels with the polymer electrolyte, oxymethylene linked poly(ethylene oxide) - lithium triflate [(a-PEO)n(LiCF3SO3)]. The resulting nanocomposite is a mixed ionic-electronic conductor in which the ionic charge carriers in the polymer electrolyte are in intimate contact with the electronic charge carriers in the V205 xerogel. Variable-temperature electronic conductivity and thermoelectric power measurements have been performed to examine the charge transport properties.
