Title (EN) FRACTAL-LIKE POLYMERIC PARTICLES AND THEIR USE IN DIVERSE APPLICATIONS
(FR) PARTICULES POLYMÈRES DE TYPE FRACTAL ET LEUR UTILISATION DANS DIVERSES APPLICATIONS
Abstract: front page image
(EN)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.
(FR)Particules polymères de type fractal ayant une structure ramifiée hiérarchique. Les particules ont des fibres ayant des diamètres de l'ordre du nanomètre sur leurs périphéries, ce qui permet un certain nombre de propriétés uniques et hautement souhaitables. Les particules sont fabriquées par un procédé combinant des forces de cisaillement et de séparation de phase de différentes solutions, en particulier une solution polymère. En outre, les particules peuvent être utilisées comme revêtements, non tissés, textiles et modificateurs de viscosité et adhésifs, entre autres applications.
