Abstract
The present invention relates to a powdered mix of a phase change material blend. The blend includes a polar phase change material bound substantially to at least one surface of a clay matrix having a surface charge, wherein the blend is present in a powdered form at temperatures above and below the phase change temperature of the polar phase change material. The present invention also relates to a method of making the powdered mix of a phase change material blend and a therapy pack including the powdered mix of a phase change material blend.
Claims21
A powdered mix of a phase change material blend comprising:
- a polar phase change material bound substantially to at least one surface of a clay matrix having a surface charge to form a blend, wherein the blend is present in a powdered form at temperatures above and below a phase change temperature of the polar phase change material.
A method of making a powdered mix of a phase change material blend comprising:
- mixing a clay matrix having a surface charge with a polar phase change material under conditions effective to bind the polar phase change material substantially to at least one surface of the clay matrix in a powdered form at temperatures above and below a phase change temperature of the polar phase change material.
A therapy pack comprising:
- an outer material encapsulating a powdered mix of a phase change material blend, wherein the phase change material blend comprises a polar phase change material bound substantially to at least one surface of a clay matrix having a surface charge and wherein the blend is present in a powdered form at temperatures above and below a phase change temperature of the polar phase change material.
