Cellulose acetate based electrolyte characterization for application in polymer electrolyte / Siti Fadzilah Ayub

Cellulose acetate film containing salt and plasticizer cellulose acetate-salt complexes was used to obtain some insight on mechanism of ionic conductivity in cellulose acetate-based polymer electrolytes. In this study, cellulose acetate film is largely amorphous. Mobile ions, NH/ from NH4CF3SO3 are...
