  • Publication number: 20220403173
    Abstract: The present invention includes methods of making a nanocellulosic composition comprising one or more nanocellulosic components, wherein the one or more nanocellulosic components comprise a micron-scale cellulose or cellulose nanofibrils (CNF), the method comprising the steps of: creating a nanocellulosic slurry by combining the one or more of nanocellulosic components with a liquid component; and exposing the nanocellulosic slurry to a drying condition, wherein the drying condition comprises microwave radiation, thereby creating a nanocellulosic composition. The present invention also includes compositions comprising cellulose (nanocellulosic compositions), wherein the nanocellulosic compositions have an internal void space of about 5% to about 95% by volume.

  • Patent number: 10875284
    Abstract: Strong, light-weight composite laminates are made by impregnating layers of paper with a cellulose nanofiber (CNF) slurry, laying the coated papers up in a plurality of layers or stack, and subjecting the stack to pressure and heat for a period of time sufficient to cause the CNF to impregnate, reinforce, and bond the paper layers into a composite. The resulting composite has impressive mechanical strength and exhibits a substantially homogeneous composition throughout its depth. The composite should have good strength to weight properties, and be recyclable or compostable.
