Abstract: A method of forming a substrate in a thermal compression bonding process that permit substantially greater amounts of fillers than previously accomplished. The method employs a dispersion of a thermoplastic binder and a filler. The dispersion is then thermally compression bonded to form a substrate. Lightweight fillers are one example of fillers that are ideally suited for the thermal compression bonding through the use of a dispersion. Such lightweight fillers enable the formation of a substrate with a very low and desirable specific gravity.

Abstract: A method of treating a biobased feedstock derived from agricultural resources and specifically from the non-distillate products of fermentation-derived renewable fuel and distilled spirit processes.

Abstract: The deposition of graphene is accomplished by various techniques that result in a change of the graphene's solubility in the liquid medium. The solubility change enables the deposition of the graphene onto the substrate. Once the graphene is deposited onto the substrate, the at least partially coated substrate may be separated from the liquid medium. The substrates may then serve as a carrier to deliver the graphene to a desired application.

Abstract: A polymeric matrix is melt processed with reactive monomers or oligomers that are miscible in the polymeric matrix. Upon initial melt processing and mixing, the reactive monomers or oligomers contained within the resulting polymeric matrix are cured with actinic radiation to form a polymeric alloy. The alloy of the polymeric matrix and the cured polymer possesses a non-equilibrium morphology and a surface energy that is effectively secured for a desired application and use after subsequent compounding.
