Fremgangsmåde til fremstilling af nanostrukturer i membraner og asymmetriske membraner

A process for preparation of nano structures in membranes where a polymer membrane is irradiated with charged particles, especially ions, to give particle traces, which etch the membrane under the action of an etching fluid, and the etching action is stopped by use of a stopping liquid, as a result...

Beschreibung
Zusammenfassung:	A process for preparation of nano structures in membranes where a polymer membrane is irradiated with charged particles, especially ions, to give particle traces, which etch the membrane under the action of an etching fluid, and the etching action is stopped by use of a stopping liquid, as a result of which an asymmetrical structure is produced, the polymer material being polyimide is new. An Independent claim is included for a membrane with asymmetrical pores consisting of polyimide and obtained as above.
