Abstract: The present invention involves the production of fibers and fabrics with improved thermal conductivity and thermal stability. The improvement is accomplished by incorporating nanoscale anisotropic materials, that are <500 nm on the minor axis, have aspect ratio (length compared to width) of at least 2, and possess thermal conductivity values >1 W/mK. The invention has been demonstrated in various polymer systems such as but not limited to polyamides, thermoplastic urethanes, polypropylene, polyethylene and other thermoplastics. As well, various fiber production technologies were practiced such as melt spinning (thermo-plastics), dry/wet spinning (elastomerics) and gel spinning (UHMW polyethylene, poly-(p-phenyleneterephtalamide)) to produce said fibers. Fabric woven from said fibers maintains the improved thermal performance and has application in a broad spectrum of thermal management opportunities.
