Abstract

Solid polymer electrolyte (SPE) films were developed from poly(L-lactic acid)-poly(propylene glycol) (PLLA-PPG) with ethylene carbonate (EC) or propylene carbonate (PC) as plasticizer and lithium perchlorate (LiClO4) salt using solution casting method. The conductivity behaviours of the samples prepared were studied by electron impedance spectroscopy (EIS). From the EIS analysis, PLLA-PPG with 30 wt.% of EC and 25 wt.% of LiClO4 shows the highest conductivity value of 4.57 × 10-5 S cm-1 at room temperature. The attenuated total reflection-Fourier transform infrared spectroscopy (ATR-FTIR) confirm that there is chemical interaction between polymer host and lithium cation from lithium perchlorate. The shift of wavenumber for carbonyl (C=O) and ether (C-O-C) can be seen in ATR-FTIR spectrum. The crystallinity of PLLA was studied using X-ray diffraction (XRD) analysis. The absence of diffraction peaks corresponding to LiClO4 in SPE, which indicates that LiClO4 solvates well in the PLLA-PPG film. Thermal study by TGA indicated that PLLA-PPG SPE was thermally stable up to 270 ºC.
