Abstract

In addition to being efficient solvents for biopolymers, several ionic liquids (ILs) have been shown to be effective solvents for synthetic polymers such as meta-aramids, i.e., Nomex ® (1-5). In this report, meta-aramid/cotton composites are generated by the partial dissolution of fibrous materials. Composite materials are characterized by scanning electron microscopy (SEM), thermogravimetric analysis (TGA), and flammability testing. Results suggest that the ionic liquid facilitated processes demonstrated are potentially powerful methods for enhancing the thermal stability and flammability characteristics of biopolymers without the denaturation of important native micro and meso structures.
