Syndiotactic polystyrene (s-PS) microfibers with a microporous crystalline form have been successfully prepared with eco-friendly solvents through a cost effective process, which can be easily scaled up for large scale production. These microporous fibers are characterized by high sorption capacity and fast sorption kinetics of volatile organic compounds from air, which are comparable with those of Tenax (R), a commercial benchmark sorption material. Excellent sorption properties, associated with safe and manageable morphology as well as simple and eco-friendly preparation/regeneration procedures, make these microporous s-PS microfibers particularly suitable as filter sorption medium to remove traces of pollutants from moist air.
