Patents by Inventor Daniel Knopf

Daniel Knopf has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method for preparing modified nanocrystalline cellulose
    Patent number: 10647783
    Abstract: The present disclosure provides methods for functionalizing the surfaces of cellulose nanoparticles. In embodiments, nanoparticles are aerosolized, and then passed through a flow reactor where they are contacted with gaseous reactants to functionalize the surface of the nanoparticles. In other embodiments, the nanoparticles are aerosolized, and then passed through a plasma reactor where they are contacted with gaseous reactants to functionalize the surface of the nanoparticles. Once the functionalized nanoparticles are produced, they may be combined with polymers to form polymer composites having both a polymer and the functionalized nanoparticles. Systems for producing these functionalized nanoparticles, coupled with downstream polymer processing equipment for forming the polymer composites, are also provided.
    Type: Grant
