Abstract:
1. A high thermal conductivity resin comprising: a host resin matrix; and high thermal conductivity fillers, wherein said high thermal conductivity fillers are mixed within said host resin matrix to form a resin mixture; wherein said fillers comprise at least 3-5% by weight of said resin mixture; wherein said high thermal conductivity fillers are an average of 1-100 nm in at least one dimension and are smaller than an average of 1000 nm in a longest dimension of said fillers; wherein said host resin matrix forms ordered resin shells around said high thermal conductivity fillers; wherein resin molecules are aligned perpendicular to a surface of said high thermal conductivity fillers; wherein an overlap of said ordered resin shells is formed between said high thermal conductivity fillers such that continuous pathways for increased phonon flux are created through said resin mixture; and wherein said fillers are comprised of larger particles and smaller particles, wherein said larger particles have at least one size dimension that is greater than 100 nm, and wherein said smaller particles have at least one size dimension that is smaller than 100 nm.
