Abstract

Disclosed are cellulose-based flexible gels containing cellulose nanorods, ribbons, fibers, and the like, and cellulose-enabled inorganic or polymeric composites, wherein the gels have tunable optical, thermal, and mechanical properties. The disclosed gels can be in the form of hydrogels, organogels, liquid-crystal (LC) gels, and aerogels.
