Formation of core (polystyrene)-shell (polybenzimidazole) nanoparticles using sulfonated polystyrene as template

► Formation of core (polystyrene)-shell (polybenzimidazole) nanoparticles. ► Blends of polybenzimidazole with sodium salt of sulfonated polystyrene. ► Blending is caused by the disruption of polybenzimidazole chains self association. ► Higher sulfonation of SPS-Na favors the core-shell formation.
