Conductivity studies of cellulose acetate based composite polymer electrolytes / Nur 'Atiah Che Ahmad

In this study, Cellulose Acetate (CA) based polymer electrolytes containing different concentrations of ammonium trifluoromethanesulfonate (NH₄CF₃SO₃) were prepared by the solution casting technique. An impedance investigation was conducted to determine the electrical conductivity of each sample. The conductivity was calculated using bulk resistance value in the frequency range between 100 Hz and 1MHz at various temperatures ranging from 303 K to 383 K. The highest conductivity at room temperature for the sample containing lg CA doped with 35% NH₄CF₃SO₃ was 1.29x10⁻⁴ Sonˉ¹ .Upon addition of 3% Silicon Dioxide (SiO₂) exhibited the highest electrical conductivity of 2.5lxl0ˉ3 Scm⁻¹.
