  • Polymer-micelle complex as an aid to electrospinning
    Patent number: 10087553
    Abstract: A polymer-micelle complex suitable for use as an aid to preparing fibers, particularly nanofibers, by electrospinning. The polymer-micelle complex may be designed to impart viscosity, surface tension and conductivity properties optimal for electrospinning. By incorporating the complex as a secondary ingredient, one may electrospin sparingly soluble or low molecular weight polymers. Moreover, the polymer-micelle complex can be used as a generic carrier for preparing fibers incorporating other desired materials, such as rigid or globular (hard-to-spin) polymers, enzymes, cells, viral particles and nanoparticles.
    Type: Grant
    Filed: April 12, 2018
    Date of Patent: October 2, 2018
    Assignee: The United States of America as Represented by the Secretary of the Army
    Inventors: Ramanathan Nagarajan, Christopher P Drew, Charlene M Mello
