Abstract:
[Summary] [Object] For a heat storage material containing heat storage capsule, to ensure favorable adsorption/desorption performance without reduction in heat storing performance even under a condition where an organic solvent (in particular, evaporable fuel of mixture of alcohol and gasoline) or a condition where moisture is present. [Solution] In a method of manufacturing a heat storage material containing heat storage capsules including a phase change material absorbing/discharging latent heat in accordance with change in temperature, the phase change material being charged in outer shells of the heat storage capsules, the method including the steps of binding a periphery of mutually contacting portions of a plurality of heat storage capsules with a molding binder, thereby to mold a granular molded heat storage material, coating an outer peripheral surface portion of the molded heat storage material with a coating binder to form a coating layer thereon and subjecting the coated molded heat storage material having the coating layer to a reaction promoting treatment for promoting a polymerization reaction of at least the coating binder in the coating layer.
Abstract:
The present invention provides a reversible piezochromic system that changes appearance upon application of a mechanical force. The reversible piezochromic system includes a cavity defined by a first substrate and a second substrate. The cavity includes at least a first fluid. The first fluid spreads when a mechanical force is applied to the system. The relaxation time of the first fluid depends upon the internal forces of the system. These internal forces at least include the surface energy differences between the substrates and the fluid or fluids, and the rheological properties of the fluid or fluids.
Abstract:
A composite structure comprising: a first stack comprising a plurality of plies of composite material and at least one ply of self-healing material, the ply of self-healing material comprising a plurality of containers each containing a curable healing liquid; and a second stack comprising a plurality of plies of composite material, the stacks being joined together at a bond line. By placing a ply of self-healing material in one of the stacks (preferably relatively close to the bond line) the ply of self-healing material can resist the propagation of cracks between the first stack and the second stack. Preferably the global strength of the first stack is greater than the global strength of the second stack.
Abstract:
A novel adhesive formed in situ in a microcapsule and method for forming such a pressure sensitive or flowable adhesive in situ in a microcapsule is disclosed. The method for forming the novel adhesive comprises providing an aqueous mixture of wall material in water; adding a substantially water insoluble core material, free radical initiator, and a solvent for the pre-polymers to the aqueous mixture. The core material comprises a first addition polymerizable pre-polymer having a Tg of less than about 0° C., a flash point of at least 75° C., and a boiling point of at least 175° C. These are typically selected from acrylate or methacrylate type materials. Optionally included is a second addition polymerizable pre-polymer for providing cross-linking or interaction between polymer chains. High shear agitation is provided to the aqueous mixture to achieve a particle size of about 0.1 to 250 microns. Stirring at a first temperature effects capsule wall formation; and heating to a second temperature polymerizes the pre-polymers of the core material to form an adhesive in situ in the formed capsules.
Abstract:
A thermal barrier (30) for controlling heat transfer across through buildings, appliances and textile products is disclosed. The thermal barrier (30) includes opposing, spaced apart sheets (33, 34) which define at least one chamber therebetween. A temperature stabilizing material (31) is disposed in the chamber. The temperature stabilizing material (31) is preferably a phase change material such as paraffinic hydrocarbon, hydrated salt, plastic crystal or glycol. In one embodiment, an interconnecting structure (35) is disposed between opposing sheets (33, 34) to create a plurality of cells (36) of the chamber into which the temperature stabilizing material (31) is uniformly disposed. A method of manufacturing the thermal barrier (30) is also disclosed.
Abstract:
An oxygen absorbing composition having an effective amount of at least one oxygen absorbent contained in an emulsion. An oxygen absorbing product is produced by dispersing an oxygen absorbent in an emulsion to form an oxygen absorbing composition and transferring the oxygen absorbing composition onto a substrate.
