Thermal interface material and method for making the same

摘要

A thermal interface material ( 100 ) includes a macromolecular matrix ( 10 ) and a plurality of thermally conductive fibers ( 20 ) incorporated therein. The macromolecular matrix ( 10 ) has a first surface ( 11 ) and an opposite second surface ( 12 ). Each of the thermally conductive fibers ( 20 ) is substantially parallel to each other and extends between the first and second surfaces ( 11 ), ( 12 ). A method for manufacturing the thermal interface material includes the steps of: (a) providing a number of thermally conductive fibers; (b) aligning the thermally conductive fibers uniformly and directionally to form an array of the thermally conductive fibers; (c) immersing the array of thermally conductive fibers into a liquid macromolecular material; (d) solidifying the liquid macromolecular material to obtain a macromolecular matrix having the two opposite surfaces with the thermally conductive fibers embedded therein, that is, a desired interface material is obtained.
