    Abstract: A method of forming a microporous fluoropolymer membrane comprising the steps of: irradiating a sheet of fluoropolymer at a dosage level below the rupture energy of the carbon-to-fluorine (C-F) bonds of the fluoropolymer, but sufficient to rupture carbon-to-carbon (C-C) bonds; and exposing the sheet of fluoropolymer to an etching for a period of time sufficient to etch away disrupted atoms and molecules, wherein continuous microphages are formed through the sheet.

    Abstract: A membrane consisting of dielectric material such as an organic polymer, separates two chambers of an electrolytic cell from each other. The membrane is produced using an etching solution which is provided in one of the chambers. Said etching solution contains active etching ions which etch the organic polymer. The other chamber contains a solution which does not have an etching action. An electrical field is generated through the membrane with an electrode that is dipped into the respective electrolytes and a voltage source connecting the two electrodes. The etching process makes its way along the ion tracks on one side, through the membrane and first produces one funnel-shaped pore per ion track. Immediately prior to the breakthrough, the ions which do not have an etching action begin to penetrate the still existent thin layer with fine pores - the active layer - and to displace the ions with an etching action at the exit point. An intensified electric current, driven by the adjacent field, is established. The etching process on the floor of the pore shifts sideways according to the concentration of etching ions still present. The process can be stopped by deactivating the field and washing the membrane and the sole size, i.e. the active layer size, adjusted. A membrane produced in this way can be operated as an electrochemical valve and can be used with one or more pores as a sensor or with many pores to control concentration.
