in this work, electrocatalyst with core-shell structure (pd as core and pt as shell on vulcanxc-72r) was synthesis. not only this structure can reduce the amount of platinum but it also can increase the gas diffusion electrode (gde) performance in cathode reaction (oxygen reduction reaction or orr) of polymer electrolyte membrane fuel cell (pemfc). to this meaning, one series of electrocatalyst...

In this work we fabricate and characterize field-effect transistors based on the solution-processable semiconducting polymer poly(3-hexylthiophene) (P3HT). Applying two independent gate potentials to the electrolyte-gated organic field-effect transistor (EGOFET), by using a conventional SiO(2) layer as the back-gate dielectric and the electrolyte-gate as the top-gate, allows the measurement of ...

The effect of carbon nanofibers (CNFs) on the electrical properties of Poly(vinylidene fluoride-hexafluoropropylene) (P(VdF-HFP)) based gel polymer electrolytes has been investigated in the present work. The length and diameter ranges of CNFs used in the present work are 5-50 μm and 200-600 nm respectively. The nanocomposite gel polymer electrolytes have been synthesized by solution casting tec...

Recent advances in the study of ionic liquids based gel polymer electrolytes have been briefly reviewed in view of their electrochemical applications, particularly, their application as electrolytes in supercapacitors. The incorporation of ionic liquids in gel polymer electrolytes, instead of organic solvents like propylene carbonate, ethylene carbonate, etc., provide added effect in terms of t...

Lithium ions solvated by polyethylene-oxide ~PEO! have been confined by intercalation within the galleries of an insulating, inorganic layered solid CdPS3 . The dc conductivity of this confined polymer electrolyte Cd0.75PS3Li0.5(PEO) displays a distinct change in the mechanism of conduction with temperature, exhibiting a crossover from an Arrhenius temperature dependence at low temperatures to ...

PVDF polymer, LiClO4 salt doped polymer electrolyte, PVDF/PEG blend and electrolyte thin films prepared via solution cast method further these undergone with different characterization techniques i.e. XRD, FTIR, SEM DSC. XRD results confirmed that reduction in crystalline nature of the presence PEG salt. FTIR spectra revealed complexation/interaction polymers. Shifting glass transition temperat...
