Abstract: A method of making a resin composition is described comprising providing a mixture of boron nitride particles and cellulose nanocrystals and combining the mixture with a resin composition. The weight ratio of boron nitride to cellulose nanocrystals typically ranges from 99.9:0.1 to 90:10. The resin composition can have a viscosity at least a 5, 10, 15, 20 or 25% lower than the same composition without the cellulose nanocrystals, which facilitate processing efficiency and is also amenable to incorporating higher boron nitride concentrations into the resin composition. Also described is a (e.g. powder) composition comprising premixed boron nitride particles and cellulose nanocrystals and resin composition comprising such (e.g. powder) composition.

Abstract: Polymer matrix composite comprising a porous polymeric network; and a plurality of thermally conductive particles distributed within the polymeric network structure; wherein the thermally conductive particles are present in a range from 15 to 99 weight percent, based on the total weight of the thermally conductive particles and the polymer (excluding the solvent); and wherein the polymer matrix composite has a density of at least 0.3 g/cm3; and methods for making the same. The polymer matrix composites are useful, for example, in electronic devices.
