  • Publication number: 20130274406
    Abstract: A reinforced fluoropolymer composite is presented, which includes a fluoropolymer and a fluoro-functionalized nanocrystalline cellulose in which the outer circumference of the nanocrystalline cellulose has been functionalized with fluorinated substrates. The fluoro-functionalized nanocrystalline cellulose may be used to produce stable dispersions with fluoropolymers exhibiting enhanced adhesion between the nanocrystalline particles and fluoropolymer in a composite material, and decreased surface free energy of the cellulose surface.
