摘要： A heat conductive sheet of the present invention is a heat conductive sheet containing a curing reaction catalyst, wherein a heat conductive uncured composition 2 not containing a curing reaction catalyst is joined to at least one principal surface of the heat conductive sheet 1 containing a curing reaction catalyst. The heat conductive sheet 1 containing a curing reaction catalyst contains the curing reaction catalyst in an amount necessary to cure the heat conductive uncured composition. A mounting method of the present invention includes: joining a heat conductive uncured composition 2 not containing a curing reaction catalyst to at least one principal surface of the heat conductive sheet 1 containing a curing reaction catalyst, and curing the heat conductive uncured composition by diffusion of the curing reaction catalyst contained in the heat conductive sheet 1. Thereby, the heat conductive uncured composition can be joined to the heat conductive sheet immediately before mounting to an electronic component or the like, easily follow the unevenness of a heat generating part and/or heat dissipating part, and cure after mounting.

摘要： (Co)polymer matrix composites including a porous (co)polymeric network; a multiplicity of thermally-conductive particles and a multiplicity of magnetic particles distributed within the (co)polymeric network structure; wherein the thermally-conductive particles, magnetic particles and optional magnetic 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). 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 thermal interface materials that also provide magnetic properties useful, for example, in flux field directional materials or shielding from electromagnetic interference.
