摘要： Microcapsules or macrocapsules have a core composition that includes a phase changing material (PCM) encapsulated within a polymer wall with an outer shell having a siloxane tethered to an exterior surface of the polymer wall by a surfactant. The siloxane may form a crystalline or a sol-gel outer shell. Methods of making such capsules and textile fabrics and clothing incorporating such capsules include treating pre-formed capsules with a surfactant solution followed by treating with a compound containing a siloxane functional group. The surfactant connects or tethers the siloxane to the exterior surface of the polymer wall and the siloxane forms an outer shell of the capsules.

摘要： Ruptureable, dual reagent mono-capsules are disclosed that have a core composition, which includes a first reagent, encapsulated within a polymer wall, and a shell connected to an exterior surface of the polymer wall by a surfactant. The shell is made from a second reagent that is chemically bonded to the surfactant by a chemical electrostatic interaction. Upon rupture of the polymer wall of the mono-capsule, the first reagent and the second reagent chemically react with one another to form a reaction product.

摘要： Methods for producing microcapsules begin by preparing an emulsion of a surfactant, core material, and water, followed by the addition of a crosslinking agent and a melamine formaldehyde prepolymer, which is subsequently polymerized. The crosslinking agent is added before the melamine formaldehyde prepolymer, with a first addition or a second addition of a melamine formaldehyde prepolymer, or is divided for addition with both a first addition and a second addition of melamine formaldehyde prepolymer. The crosslinking agent is a mixture of a reaction product of a cyclic urea (U) and a multifunctional aldehyde (A), and at least one crosslinker selected from the following group: a reaction products of (i) an aminotriazine and at least one aldehyde selected from the group consisting of aliphatic monoaldehydes and multifunctional aliphatic aldehydes, (ii) urea and/or cyclic ureas and formaldehyde, or (iii) phenols and aliphatic monoaldehydes, or from alkoxycarbonylaminotriazines, or multifunctional isocyanates, epoxides, aziridines, and carbodiimides.

摘要： Solid gel beads formed from a gel product of a 5 carbon to 60 carbon alkane phase change material, 5 carbon to 60 carbon alkene phase change material, or a combination thereof and a styrene-based polymer are homogeneous, has an uneven exterior surface, and a major axis length in a range of 1000 μm to 100 mm. Methods for making the solid gel bead include providing water having a preselected temperature based on a linear relationship to the melting point of a phase change material composition, mixing the phase change material composition with the styrene-based polymer at or below the preselected temperature with stirring to form a pulp, and mixing the pulp into the water with turbulent mixing while maintaining the temperature of the mixture at the preselected temperature.

摘要： Methods for producing a dimensionally stable phase change material (PCM), and dimensionally stable PCMs are disclosed. The methods include providing a porous base material, mixing a phase change material having a polar functional group with a substance that increases the polar attraction of the phase change material for the porous base material to form a mixture thereof; and, thereafter, mixing the mixture with the porous base material until a selected saturation of phase change material in the porous base material is reached. The methods may include filtering the porous base material after the selected saturation is reached to form a cake of dimensionally stable PCM and, thereafter, reducing the size of the dimensionally stable PCM to an average mean particle size of about 10 to about 50 μm, or more preferably 20 to 30 μm.
