Abstract

Palm-based polyurethane solid polymer electrolyte was prepared via prepolymerization method between palm kernel oil based polyols (PKO-p) and 2,4'-diphenylmethane diisocyanate (2,4'-MDI) in acetone at room temperature with the vary amount of lithium trifuoromethanesulfonate (LiCF3SO 3) salt and polyethylene glycol (PEG). The film was analyzed using attenuated total reflection infrared (ATR-IR) spectroscopy, electrochemical impedance spectroscopy (EIS) and X-ray diffractometry (XRD). EIS result indicated ionic conductivity obtained with 30 wt%LiCF3SO3 increased to 6.55 × 10-6 S cm-1 when 10 wt.% of plasticizer was added into the system. FTIR analysis showed the interaction between lithium ions and amine (-N-H) at 3600-3100 cm-1, carbonyl (-C=O) at 1750-1650 cm-1 and ether (-C-O-C-) at 1150-1000 cm -1 of the polyurethane forming polymer-salt complexes. The XRD result confirmed that LiCF3SO3 salt completely dissociated within the polyurethane film with the absence of crystalline peaks of LiCF 3SO3.
