Grand Challenges in Fabrication of Nanocomposite Hollow Fiber Membranes

Membrane processes allow scalable and energy-efficient separation of gas liquid, advance low-carbon purifications in various industrial environmental applications enable more resilient economy society. In pursuit developing advanced membranes with continuously improved separating performances, nanofillers have been commonly incorporated into to upgrade membrane properties such as mechanical robustness, antifouling ability, permeability etc., across all types popular geometries from flat sheet spiral wound hollow fiber. Nanofillers inside fibre received attentions due the unique structural advantages a large surface area/volume ratio compact module designs. The resultant nanocomposite fiber thus combine superiority specific functions nanomaterials superhydrophilicity or catalytic activity, whereas development dual layer allowed further design both inner outer layers innovative functions. On other hand, greener environmentally friendly fabrication are increasingly important sustainable technology, for example topics using natural polymers, solvent free nano-pollutions fervently investigated.
