Abstract
|
While
there are studies focusing on their continuous growth on inorganic
substrates, MOF–polymer membranes are in demand for separation because of
their low cost, high processing ability and large membrane area. To achieve
this purpose, the flexibility of the polymer must be reduced.
The MOF-to-substrate adhesion strength should be greatly enhanced. Researchers fabricated a continuous and well inter-grown Cu3(BTC)2–PAN composite membrane by directly growing via a covalent linker. Dehydrogenation, cyclization and crosslinking reactions of the PAN hollow fiber by solvothermal treatment can greatly improve the stiffness and compression strength of the composite membrane. |
