Beschreibung
Zusammenfassung:	Disclosed herein is an aqueous dispersion and a method for making said dispersion, and more particularly, a dispersion that comprises a nanoclay such as a tubular clay (e.g. halloysite), a fluoropolymer and the requisite surfactants for dispersion stability. In various embodiments, and applications thereof to substrates and the like, the dispersion improves the manufacturability of articles that include coating fluoropolymer dispersions while retaining the unique properties of the fluoropolymer coating. L'invention concerne une dispersion aqueuse et un procédé destiné à préparer cette dispersion et, plus particulièrement, une dispersion qui comprend une nanoargile, telle qu'une argile tubulaire (par exemple de l'halloysite), un fluoropolymère et les tensioactifs requis pour une stabilité de la dispersion. Dans divers modes de réalisation et lors de son application sur des substrats et similaires, la dispersion améliore la fabricabilité d'articles qui comprennent des dispersions de fluoropolymère de revêtement, tout en conservant les propriétés uniques du revêtement de fluoropolymère.
