  • FRACTAL-LIKE POLYMERIC PARTICLES AND THEIR USE IN DIVERSE APPLICATIONS
    Publication number: 20240076509
    Abstract: Fractal-like polymeric particles having a hierarchical, branched structure are disclosed. The particles have fibers with nanometer-scale diameters on their peripheries, which enables a number of unique and highly desirable properties. The particles are fabricated by a method combining phase separation and shear forces of different solutions, in particular a polymer solution. In addition, the particles may be used as coatings, nonwovens, textiles and viscosity modifiers and adhesives, among other applications.
    Type: Application
    Filed: March 18, 2022
    Publication date: March 7, 2024
    Inventors: Orlin D. Velev, Sangchul Roh
