The invention relates to a coated article having enhanced reversible thermal properties. The coated article comprises a substrate having a surface and a coating covering a portion of the surface and comprising a polymeric material and a temperature regulating material dispersed in the polymeric material. The coating is formed with a plurality of regions of discontinuity that are separated from one another and expose a remaining portion of the surface to provide improved flexibility, softness, air permeability, or water vapor transport properties. The coated article may be used in apparel, footwear, medical products, containers and packagings, building materials, appliances, and other products.

What is claimed is: 1. A coated article having enhanced reversible thermal properties, comprising: a substrate having a surface; and a coating covering a portion of the surface and comprising a polymeric material and a non-encapsulated phase change material dispersed in the polymeric material, wherein the non-encapsulated phase change material is a solid/solid phase change material, and the coating is formed as a plurality of coating regions that are distributed substantially uniformly across the surface and are separated from one another to provide improved flexibility and air permeability to the coated article. 2. The coated article of claim 1, wherein the substrate is a fabric, film, foam, or leather. 3. The coated article of claim 1, wherein the non-encapsulated phase change material has a transition temperature in the range of 22째 to 40째 C. 4. The coated article of claim 3, wherein the transition temperature of the non-encapsulated phase change material is in the range of 22째 to 28째 C. 5. The coated article of claim 1, wherein the coating covers between 1 to 99 percent of the surface of the substrate. 6. The coated article of claim 5, wherein the coating covers between 50 to 90 percent of the surface of the substrate. 7. The coated article of claim 1, wherein at least two coating regions have different shapes or sizes. 8. The coated article of claim 1, wherein the coating regions have shapes that are independently selected from the group consisting of circular, half-circular, diamond-shaped, hexagonal, multi-lobal, octagonal, oval, pentagonal, rectangular, square-shaped, star-shaped, trapezoidal, triangular, and wedge-shaped. 9. The coated article of claim 1, wherein the coating regions have sizes ranging from 1 mm to 4 mm. 10. The coated article of claim 1, wherein the solid/solid phase change material comprises a polyhydric alcohol selected from the group consisting of 2,2-dimethyl-1,3-propanediol, 2-hydroxymethyl-2-methyl-1,3-propanediol, ethylene glycol, pentaerythritol, dipentaerythritol, pentaglycerine, tetramethylol ethane, neopentyl glycol, tetramethylol propane, 2-amino-2-methyl-1,3-propanediol, monoaminopentaerythritol, diaminopentaerythritol, and tris(hydroxymethyl) acetic acid.
