  • Patent number: 11186689
    Abstract: This invention concerns a novel method to produce thermosets such as epoxies and polyurethanes comprising nano-cellulose. The method comprises contacting primarily water-bourne dispersed nano-cellulose with liquid thermoset precursors, specifically epoxy or amine in the case of epoxies, or glycols or similar in the case of polyurethanes. Nano-cellulose transfers to the organic phase, and water is removed at temperatures below 100° C. Thereafter the organic phase comprising nano-cellulose can be mixed with the reactive counterpart to yield nano-composites with improved properties. The products can be used for composite articles, coatings, adhesives, sealants, and other end-uses. Preferred embodiments are described in detail.
