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.
