摘要

Procedure for preparing a Polyamide Membrane insoluble in alcohol, Hydrophilic, Microporous, without skin and Surface Properties of surface modified with controlled Porosity.It includes the following Operations: First, prepare a Solution casting, which comprises a casting Resin system and a system that is Soluble in the Solvent casting Resin System; Second, it induces the nucleation of the casting solution by controlled addition of a di The Solvent system to form a Resin casting, casting composition; Third,Extends the casting composition on a substrate to form a Thin Film on the substrate; Fourth, Gets in contact and the Film Composition is diluted with a Solvent casting System of said Liquid casting Resin System; and finally, washed the membra Na formed to remove the Solvent and then dried.
