Abstract: A composite manufacture includes an extrudable thermoplastic matrix and a photochromic colorant, the photochromic colorant conferring to the composite a reversible strain-induced color change property. Methods include adding photochromic colorant to an extrudable thermoplastic polymer matrix to form a mixture, heating the mixture to form a composite, the photochromic colorant conferring to the composite a reversible strain-induced color change property. The composite manufactures can be used in cable coatings permitting visual detection of mechanical stresses in a wire based on the reversible strain-induced color change property.

Abstract: Provided is a method of forming a conductive polymer composite. The method includes forming a mixture. The mixture includes a first thermoplastic polymer, a second thermoplastic polymer and a plurality of metal particles. The first thermoplastic polymer and the second thermoplastic polymer are immiscible with each other. The plurality of metal particles include at least one metal that is immiscible with both the first thermoplastic polymer and the second thermoplastic polymer. The method includes heating the mixture to a temperature greater than or equal to a melting point of the metal.
