Abstract: (Co)polymer matrix composites including a porous (co)polymeric network; a multiplicity of thermally-conductive particles, and a multiplicity of endothermic particles distributed within the (co)polymeric network structure; wherein the thermally-conductive particles and endothermic particles are present in a range from 15 to 99 weight percent, based on the total weight of the particles and the (co)polymer (excluding the solvent). Optionally, the (co)polymer matrix composite volumetrically expands by at least 10% of its initial volume when exposed to a temperature of at least 135° C. Methods of making and using the (co)polymer matrix composites are also disclosed. The (co)polymer matrix composites are useful, for example, as heat dissipating or heat absorbing articles, as fillers, thermal interface materials, and thermal management materials, for example, in electronic devices, more particularly mobile handheld electronic devices, power supplies, and batteries.

Abstract: A multilayer film comprises first, second, and third layers. The first layer comprises at least one aromatic polyester, and has a loss modulus at 1 hertz and 25° C. of at least 70 megapascals. The second layer is thermoplastic and has a loss modulus at 1 hertz and 25° C. of less than or equal to 60 megapascals and comprises a thermoplastic elastomer and a polyamide. The third layer contacts the second layer opposite the first layer and has a loss modulus at 1 hertz and 25° C. of at least 70 megapascals. The second layer is sandwiched between the first and third layers. A method of making the multilayer film by coextrusion is also disclosed.
