Abstract: A portable communication device is provided. A portable communication device includes a first nanofiber member having a first density, a second nanofiber member attached to the first nanofiber member and having a second density lower than the first density, a heat transfer member positioned on or above the second nanofiber member, and a conductive material coated on at least a portion of the first nanofiber member and the second nanofiber member. At least some of the conductive material may penetrate into the first nanofiber member or the second nanofiber member. Various other embodiments may be possible.
