Abstract: A method of preparing a thermally conductive composite including: a) mixing 15% to 60% by weight of a polymer matrix with 0% to 85% by weight of a high-aspect-ratio thermally conductive filler having an aspect ratio of at least 5:1; and (b) mixing a polymer melt obtained from step (a) with 0% to 85% by weight of a low-aspect-ratio thermally conductive filler having an aspect ratio of 2:1 or less. By changing the weight ratio, the structure and mechanical properties of the low-aspect-ratio thermally conductive filler and the high-aspect-ratio thermally conductive filler, thermal conductivity anisotropy can be tuned. A thermally conductive composite having thermal conductivity anisotropy in the range from 1 to 4 is also disclosed.

Abstract: The present invention provides new impact protection materials and the method of making the same. More specifically, the impact protection materials are polymer-based shear-thickening composite comprising a non-shear-thickening polymer matrix material and one or more shear-thickening materials. Preferably, the non-shear-thickening polymer matrix material is in an amount from approximately 5 weight percent to approximately 90 weight percent with the balance being one or more shear-thickening materials. The first type of the one or more shear-thickening materials is sol-gel based shear-thickening material in which small inorganic particles are connected in a gel network; the second type is polymer-based shear-thickening material in which polymer chains form network. Compared to the existing shear-thickening materials, the present shear-thickening materials have different molecular structure and formulation and possess properties of good impact protection and good stability.
