Abstract:
An article comprises a functional polymeric phase change material bound to a substrate. In some aspects, the functional polymeric phase change material is either covalently or electrovalently bonded to the substrate. The functional polymeric phase change material can comprise a reactive function. The substrate comprises at least one of cellulose, wool, fur, leather, polyester and nylon. Methods of producing the articles are also disclosed.
Abstract:
A coated article includes a substrate and a coating covering at least a portion of the substrate. The coating includes a binder having a glass transition temperature in the range of -110°C to -40°C. The coating also includes a set of microcapsules having sizes in the range of 1 micron to 15 microns, and at least one of the set of microcapsules is chemically bonded to either of, or both, the substrate and the binder.
Abstract:
Cellulosic fibers having enhanced reversible thermal properties and applications of such cellulosic fibers are described. In one embodiment, a cellulosic fiber includes a fiber body including a cellulosic material and a set of microcapsules dispersed in the cellulosic material. The set of microcapsules contain a phase change material having a latent heat of at least 40 J/g and a transition temperature in the range of 0°C to 100°C, and the phase change material provides thermal regulation based on at least one of absorption and release of the latent heat at the transition temperature. The cellulosic fiber can be formed via a solution spinning process, and can be used in various products where thermal regulating properties are desired.
Abstract:
A beverage container includes a beverage bottle and a label adjacent to the beverage bottle and including a set of microcapsules that contain a phase change material.

Abstract:
Polymeric composites and methods of manufacturing polymeric composites are described. In one embodiment, a set of microcapsules containing a phase change material are mixed with a dispersing polymeric material to form a first blend. The dispersing polymeric material has a latent heat of at least 40 J/g and a transition temperature in the range of 0°C to 50°C. The first blend is processed to form a polymeric composite. The polymeric composite can be formed in a variety of shapes, such as pellets, fibers, flakes, sheets, films, rods, and so forth. The polymeric composite can be used as is or incorporated in various articles where a thermal regulating property is desired.
Abstract:
Cellulosic fibers having enhanced reversible thermal properties and methods of forming such cellulosic fibers are described. In one embodiment, a cellulosic fiber includes a fiber body formed of an elongated member. The elongated member includes a cellulosic material and a temperature regulating material dispersed within the cellulosic material. The temperature regulating material includes a phase change material having a transition temperature in the range of -5°C to 125°C. The cellulosic fiber can be formed via a solution spinning process and can be used in various products where thermal regulating properties are desired. For example, the cellulosic fiber can be used in textiles, apparel, footwear, medical products, containers and packagings, buildings, appliances, and other products.
