Yongmoon M. Kwon 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).

  • Low friction polymeric compositions as well as devices and device fabrication methods based thereon
    Patent number: 8759454
    Abstract: A polymer blend is provided that includes a polycarbonate polyurethane polymer component having a water contact angle greater than 75 degrees and a polyurethane polymer component having a water contact angle less than 75 degrees. The polycarbonate polyurethane component and the other polyurethane polymer can be immiscible with respect to one another, and thus are phase separated in the polymer blend. The weight percentage of the polycarbonate polyurethane polymer component is greater than the weight percentage of the other polyurethane polymer component in the blend. The polymer blend is well suited for realizing a low friction surface of a variety of medical and non-medical devices.
