| 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. |
