Abstract

The synthesis of polymer electrolyte of sulfonated polystyrene (sPS) has been carried out from Styrofoam waste. The polystyrene was sulfonated using various concentrations of acetyl sulfate at 40 oC for 1 hour. The resulting sulfonated polystyrene was characterized using FTIR, thermal analysis, and cationic exchange capacity (CEC). FTIR data show the success of sulfonation with the appearance of sulfonate groups in PST. The thermal data showed that the addition of sulfonic agents decreased the thermal stability of polystyrene. The highest CEC was obtained for 25 mmol of acetyl sulfate addition, with a CEC of 6.610 meq/g. The characteristics of the resulting product show that sulfonated polystyrene from Styrofoam waste potentially is used as a material for advanced technology of polymer electrolytes such as fuel cells and Li-Battery separator.
