    摘要： Ligand exchange of thermochromic, LETC, systems exhibiting a reversible change in absorbance of electromagnetic radiation as the temperature of the system is reversibly changed are described. The described LETC systems include one or more than one transition metal ion, which experiences thermally induced changes in the nature of the complexation or coordination around the transition metal ion(s) and, thereby, the system changes its ability to absorb electromagnetic radiation as the temperature changes.In accordance with one aspect of the present invention, a thermochromic device is disclosed comprising at least two thermochromic layers when each thermochromic layer includes a polymer, at least one transition metal ion, at least one HεL ligand capable of forming a HεMLC with the transition metal ion and at least one LεL ligand capable of forming an LεMLC with the transition metal ion. In accordance with yet another aspect of the present invention, the thermochromic device further includes a separator between the first and second thermochromic layers to prevent intermixing of the contents of the layers.

    摘要： Thermally reversible light scattering materials are provided in accordance with the invention including a low melting, polymeric material dispersed in a polymer matrix; a first polymer which upon heating from a temperature below its melting point to a temperature above its melting point changes from a light scattering solid to a liquid, the first polymer being dispersed in a matrix provided by a second polymer to form a light scattering polymer material when cold and a less or non-light scattering material when hot; and thermally reversible light scattering materials which go from light scattering at lower temperatures to less or non-light scattering at higher temperatures. The thermally reversible light scattering materials of the invention can be incorporated in many applications including a window which can reversibly change from a privacy condition to a non-privacy or clear condition; a window which can reversibly change between displaying images or objects to obscuring images or objects; a layer which can reversibly change between being clear and frosted by cycling the temperature of the layer; a reversible display; a temperature indicating material or device.
