Electrical Conductivity Study of Polymer Electrolyte Magnetic Nanocomposite Based Poly(Vinyl) Alcohol (PVA) Doping Lithium and Nickel Salt

摘要

Composite polymer electrolyte magnetic systems composed of poly(vinyl) alcohol (PVA) as the host polymer, lithium and nickel salt as dopant were studied. The effect upon addition of lithium ions in polimer PVA had been enhanced conductivity with the increase of lithium concentration. The conductivity values were 1.19x10~(-6), 1.25x10~(-5), 4.89x~(-5), 1.88x10~(-4), and 1.33xl0~(-3) S.cm~(-1) for pure PVA and 1%, 3%, 5% and 7% LiOH complexed PVA, respectively. Meanwhile, the addition nickel salt into polymer electrolyte PVA-LiOH does not significantly change of conductivity value, on order 10~(-3) S.cm~(-1). The ionic transport is dominantly regarded by Li~+ ions present in polymer electrolyte magnetic because the atomic mass Li~+ is smaller than Ni~(2+). The absence of external magnetic field in polimer electrolyte magnetic causes the existence Ni~(2+) ions not significantly affected of conductivity.
