Kadhiravan Shanmuganathan 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).

  • Dynamic mechanical polymer nanocomposites
    Patent number: 8344060
    Abstract: Polymer nanocomposites exhibit a reversible change in stiffness and strength in response to a stimulus. The polymer nanocomposites include a matrix polymer with a comparably low modulus and strength and nanoparticles that have a comparably high modulus and strength. The particle-particle interactions are switched by the stimulus, to change the overall material's mechanical properties. In a preferred embodiment, a chemical regulator is used to facilitate changes of the mechanical properties. Methods for inducing modulus changes in polymer nanocomposites are also disclosed.
    Type: Grant
    Filed: April 8, 2009
    Date of Patent: January 1, 2013
    Assignees: Case Western Reserve University, The United States of America as Represented by the Department of Veterans Affairs
    Inventors: Christoph Weder, Stuart J. Rowan, Jeffrey R. Capadona, Dustin J. Tyler, Kadhiravan Shanmuganathan, Otto van den Berg
