| Summary: | Waste cooking oil based polyurethane composite polymer electrolytes was sythesized
by using solvent-free method and the effect of carboxymethyl cellulose as bio-filler
was investigated. The study focusing on the ionic conductivity and mechanical
properties. The films were characterized by fourier transform infrared spectroscopy
(FTIR), elecrochemical impedance spectroscopy (BIS), X-Ray diffaction (XRD),
differential scanning calorimetry (DSC) and tensile strength. The conductivity
increased when carboxymethyl cellulose was added. The highest conductivity value
was obtained is PU-LiCF3S03-15%CMC at 1.19 x 10-5 S/cm. The lowest tensile
strength at PU is 20.13 MPa and the highest at the PU-LiCF3S03-10%CMC is 34.17
MPa. It is concluded that the addition of carboxymethyl cellulose produce good ionic
conductivity and mechanical properties. The film is suitable for future application as
solid polymer electrolyte. |
