碩士 === 淡江大學 === 化學工程與材料工程學系碩士班 === 99 === The present study explored the use of two different techniques for the preparation of nanoporous network membrane mainly in nylon 6 / formic acid system. The concerned membrane formation processes consisted in the modification of conventional so-called immersion phase-inversion precipitation mechanism. The tasks were emphasized on the state variation that could be approached by physical treatment to modify the cast dope before it was immersed into the coagulation bath.
The two inversion methods were here nominated as gel-template assisted (GTA) and cryo-gelation (CGA) assisted immersion phase-inversion precipitation. The physical state of cast dope was changed diversely when the cast dope was treated under different conditions.
The gel-template assisted and cryo-gelation assisted cast dope then followed the immersion in non-solvent bath, where the mass and thermal transport induced different and complex process of phase-inversion.
The membrane morphology thus developed as well as other properties such as crystallography, thermal behavior were investigated.
The nanoporous network structure, to different extent, could be successfully achieved by either gel-template assisted or cryo-gelation assisted methods.
