PENGARUH DERAJAT SULFONASI TERHADAP KARAKTERISTIK POLIBLEND ANTARA POLISTIREN TERSULFONASI DENGAN LIGNIN

The aim of this research is to find new membrane for Polymer Electrolyte Membrane Fuel Cell (PEMFC). Polyblends between sulfonated polystyrene (PSS) and lignin were prepared by incorporating lignin into the sulfonated polystyrene with dimethyl formamide (DMF) as solvent, then the solution was evapor...
