Abstract:
A thermochromic laminate comprising:A) a base layer, said base layer having a structure contacting surface for communicating with an underlying structure, and a thermochromic contacting surface for communicating with a thermochromic layer, wherein said base layer is substantially reflective to electromagnetic radiation and substantially conductive to heat, and B) a thermochromic layer, said thermochromic layer having a base layer contacting surface for communicating with said base layer and an outer surface for communicating with said electromagnetic radiation wherein said thermochromic layer is of variable transmissivity to said electromagnetic radiation, and wherein the extent of said transmissivity is determined by the temperature of said thermochromic layer such that a change in said temperature results in a change in the transmissivity of said thermochromic layer and a change in the rate of heat transferred to, or reflected from, said underlying structure.
