Abstract

Summary: In this contribution the preparation of composite syndiotactic polystyrene (s‐PS) monolithic aerogels with nanofillers such as organically modified montmorillonite (OMMT) and graphene oxide (GO) is described. In these aerogels the crystallites that constitute the physical knots exhibit a nanoporous‐crystalline form. The aerogels preparation procedure allows the inclusion of also large amount of nanofillers, without aggregation, at least up to a content of 20 wt.%. This allows to improve mechanical and electrical properties of the nanoporous‐crystalline aerogels of s‐PS, which are particularly suitable to remove selectively traces of pollutants from water and air. Composite aerogels exhibiting large nanofiller content, can be also used as masterbatches for polymer composites.
