Netting () comprising an array of polymeric strands (), wherein the polymeric strands () are periodically joined together at bond regions () throughout the array with spaces () between adjacent strands, wherein at least a plurality (i.e., at least two) of the strands are hollow polymeric strands (i.e., a hollow core () with a sheath () surrounding the hollow core), and wherein at least 50 percent by number of the strands do not substantially cross over each other. In some embodiments, the core comprises fluid. Embodiments of nettings described herein are useful for example, for thermal transport in thermal interface articles used to control the temperature of and/or dissipate heat for electronic components and batteries or mechanical devices.

The present disclosure provides a thermally conductive article including a pad having first and second opposed major surfaces and a thickness therebetween. The thickness is formed of entangled thermally conductive fibers and at least a portion of the entangled thermally conductive fibers have at least one terminal end at the first opposed major surface, the opposed second major surface, or both. The pad is at least partially impregnated with a polymer. Another thermally conductive article is provided including a) a pad having first and second opposed major surfaces and a thickness therebetween; b) a first thermally conductive skin layer; and c) a second thermally conductive skin layer. The thickness of the pad is formed of aligned thermally conductive fibers, and at least a portion of the thermally conductive fibers have a terminal end at the first opposed major surface and the opposed second major surface. The first and second thermally conductive skin layers each include a polymeric matrix at least partially embedded in the terminal end of at least a portion of the thermally conductive fibers at the first and second major surfaces of the pad, respectively. Methods of making the thermally conductive articles are also provided.

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&#xb0; C. of at least 70 megapascals. The second layer is thermoplastic and has a loss modulus at 1 hertz and 25&#xb0; 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&#xb0; 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.
