Thin-film composite (TFC) structure has been widely employed in polymeric membrane fabrication to achieve superior performance for desalination and water treatment. In particular, TFC membranes with a thin active polyamide (PA) selective layer are proven to offer improved permeability without compromising salt rejection. Several modifications to TFCs have been proposed over the years to enhance their performance by altering the selective, intermediate, or support layer.

- Electrically-conductive membranes utilizing carbon nanostructures (CNS) show improved ion selectivity and self-cleaning capabilities, enhancing their filtration efficiency.
- A water-based method was developed to integrate CNS into alginate networks, resulting in membranes with high electrical conductivity (∼2858 S m) and effective swelling/shrinkage resistance.
- The membranes achieved notable filtration results, including 90% rejection of sodium sulfate (NaSO) and successful dye/salt separation in a two-stage process.
Nanosized zeolite Y is used in various applications from catalysis in petroleum refining to nanofillers in water treatment membranes. Ball milling is a potential and fast technique to decrease the particle size of zeolite Y to the nano range. However, this technique is associated with a significant loss of crystallinity.
