Abstract: Haze tunable assemblies and methods of forming and using the assemblies are disclosed. Exemplary assemblies include two or more substrates and a composite liquid crystal material interposed between at least two of the substrates. Exemplary assemblies exhibit large variation in haze upon application of a relatively low voltage and can retain desired transmission of visible light transmission.

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, heat transfer, and stiffness properties. The disclosed gels are in the form of hydrogels, organogels, liquid-crystal (LC) gels, and aerogels. Further disclosed are highly transparent and flexible cellulose nanofiber-polysiloxane composite aerogels featuring enhanced mechanical robustness, tunable optical anisotropy, and low thermal conductivity. Further disclosed are gels comprising cellulosic material derived from bacteria and processes for preparing bacterial cellulose gels and methods of use.
