Abstract: A thermal management assembly comprises an electrochemical cell, a heat sink, and a thermal pathway comprising a thermally interruptible interface interposed therebetween the electrochemical cell and the heat sink. The thermal pathway comprises an expandable material comprising intumescent particles. If heated to at least a first onset temperature, the expandable material expands and causes at least partial shear delamination at the first thermally interruptible interface. A composite thermal management article comprises a first layer comprising an expandable material comprising intumescent particles and a second layer comprising a thermal conductor material. The first and second layers contact each other at a thermally interruptible interface. If heated to at least a first onset temperature, the expandable material expands and causes at least partial shear delamination at the thermally interruptible

Abstract: A thermal interface layer includes pluralities of first and second particles dispersed in a polymeric binder at a total loading V in a range of about 40 volume percent to about 70 volume percent. The first and second particles have different compositions. The first particles include one or more of iron or nickel. The second particles include one or more of aluminum, magnesium, silicon, copper, or zinc. The thermal interface layer has a thermal conductivity in a thickness direction of the thermal interface layer in units of W/mK of at least K=5.1−0.17 V+0.002 V2.

Abstract: 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.

Abstract: Articles are described comprising a first substrate and a second substrate. At least one adhesive layer is disposed between the first and second substrates. The article further comprises a multilayer film within at least a portion of the adhesive layer(s). Also described is a method of disassembly comprising providing an adhesively bonded article as described herein; and separating the first substrate from the second substrate by delaminating the (e.g. multilayer) film. In other embodiments, adhesive articles (e.g. tape) are described comprising a (e.g. multilayer) film and methods of making adhesively bonded articles that comprise a (e.g. multilayer) film. Also described are methods of reworking, repairing, repurposing, or recycling an article, and articles.

Abstract: A shaped thermal filler particle has an elongate shape defined by a substantially planar first smooth surface and a second smooth surface that contacts the substantially planar first smooth surface along a planar closed path. The planar closed path has a length to width ratio of at least 1.5. The shaped thermal filler particle has a maximum linear dimension normal to the planar first smooth surface that is less than or equal to one half of the length of the closed path. A thermally conductive composition comprises from 1 to 95 percent by volume of the shaped thermal filler particles dispersed in a binder. An assembly comprises a heat source, a heat sink, and the thermally conductive composition at least partially sandwiched between the heat source and the heat sink.
