Claim 0:
1. A composition comprising:
a polymeric matrix; and
a crystalline vanadium oxide nanomaterial dispersed in the polymeric matrix, wherein the crystalline vanadium oxide nanomaterial comprises an average smallest dimension between about 100 nm and about 5 nm,
wherein the crystalline vanadium oxide nanomaterial has an insulator-metal electronic transition at a temperature between about −20° C. and about 100° C.,
wherein the insulator-metal electronic transition is accompanied by a modulation of near-infrared (NIR) light transmittance,
wherein an integrated modulation of light transmittance between about 680 nm and about 2,500 nm is between about 5% and about 75%,
wherein an onset of modulation of NIR light transmittance occurs between about 680 nm and about 1750 nm, and
wherein a dried weight:weight ratio of crystalline vanadium oxide nanomaterials to polymeric matrix is between about 0.01 to about 0.6.
