Abstract

The invention provides phase change material comprising organic phase change materials comprising a miscible organic nucleating material, seed crystal or organic nucleating agent to minimize supercooling during the crystallization of the phase change material. The miscible organic material acting as an organic nucleating material, seed crystal or organic nucleating agent, is in sufficiently small enough ratios so as not to interfere with the latent heat properties of the phase change material, but amounts sufficient to inhibit the appearance of supercooling. The organic nucleating material, seed crystal or organic nucleating agent comprises a polyolefin or polyalkene, or a polyethylene or a polypropylene, or a nanoparticle or a microcapsule thereof. The invention provides an article of manufacture, a coating, a latent heat storage unit, a liquid, a gel, an antifreeze fluid, a fluid, an ink, an oil, a lubricant, a sealant, a paint, a textile, a cloth, or a bedding.
