Patents by Inventor Nima Zohhadi

Nima Zohhadi 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).

  • Polymeric additive for strength, deformability, and toughness enhancement of cemetitious materials and composites
    Patent number: 8907050
    Abstract: Methods are generally provided for forming a polymer-cement composite. In one embodiment of the method, a plurality of dopamine monomers is dispersed in a buffer solution. Polymerization of the dopamine monomers can then be initiated, and a cement-sand mixture can be added to the buffer solution to form a composite mixture. Finally, the composite mixture can be cured to form a polymer-cement composite. Polymer-cement composites are also generally provided that, in one embodiment, include cement, sand, and poly(dopamine), with the polymer-cement composite having a compressive strength of 8000 psi.
