Sulfonated polystyrene polymer humidity sensor: Synthesis and characterization

Commercial polystyrene was sulfonated with sulfonic acid groups to a degree of 22 mol%. Polystyrene and sulfonated polystyrene were analyzed with respect to its chemical and physical properties trough titration, FT-IR, microprobe analysis and SEM. These techniques allowed us to determine the effecti...
