ULTRA-THIN POLYMERIC MEMBRANE

A ultra-thin polymeric membrane is made by coating a porous substrate, such as a ceramic monolith, with a solution of a polymer colloid, then drying the solution to form the film. The polymer is an associating polymer. The resulting membrane may be used for separating hydrocarbon species, for exampl...

Beschreibung
Zusammenfassung:	A ultra-thin polymeric membrane is made by coating a porous substrate, such as a ceramic monolith, with a solution of a polymer colloid, then drying the solution to form the film. The polymer is an associating polymer. The resulting membrane may be used for separating hydrocarbon species, for example. L'invention concerne une membrane polymère ultra-mince réalisée en recouvrant un substrat poreux, par exemple un monolithe en céramique, d'une solution de colloïde polymère et en séchant ensuite la solution de manière à former le film. Le polymère est un polymère associatif. La membrane ainsi obtenue peut être utilisée par exemple pour séparer différents hydrocarbures.
