Embodiment Construction

[0026] The present invention is a homoporous structure comprising at least one multi-block polymer, wherein at least one block comprises at least one moiety containing fluorine atoms ("fluorinated"), e.g. membranes, films, fabrics , Monolith. The incorporation of fluorine atoms imparts chemical resistance and antifouling properties to the homoporous block copolymer structure. This combination of fluorinated polymer blocks (e.g., A-B, A-B-C, A-B-C-D, or A-B-C-D-E) in a multi-block copolymer structure generated by self-assembly results in separations in non-aqueous liquid media such as organic or harsh liquid media. High permeability and high selectivity homoporous structure. In addition, fluorination adds an anti-fouling effect to the material.

[0027] Table 1 below provides non-limiting examples of block copolymer configurations. Different letters indicate different chemical compositions, where A, B, C, D, and E are each polymer blocks formed from the same monomer, and -co...

Abstract

Multi-block isoporous structures for non-aqueous and / or harsh chemical media having at least one of high separation specificity, chemical resistance, and antifouling properties, methods of manufacturing and use, for replacements or alternatives to existing separation membrane technologies.

Description

[0001] Cross references to related patent applications [0002] This application claims the benefit of priority to U.S. Provisional Patent Application 62 / 505,589, filed May 12, 2017, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to a non-aqueous chemical medium and / or harsh chemical medium-resistant multi-block homoporous structure as a substitute or substitute for the existing separation membrane technology, as well as a manufacturing method and use thereof, wherein the structure has high flux, At least one of high separation specificity, chemical resistance, and anti-contamination properties. Background technique [0004] Polytetrafluoroethylene (PTFE) or poly(vinylidene fluoride) has been produced by reacting fluorine-containing monomers (such as tetrafluoroethylene, vinylidene fluoride) to produce hydrophilic polytetrafluoroethylene (PTFE) or poly(vinylidene fluoride), or by providing a hydrophil...
