Abstract:

Over the last two decades, an enormous diversity of nanomaterials (MOFs, COFs etc.), and design of complex, multilayer constructs has promised exciting new performance and transport behaviour. Multilayer architecture of the thin layer structures has demonstrated the impact of asymmetry in nanomaterial performance. This has been complemented with advanced molecular modelling to identify how competing transport mechanisms contribute to extremely high selectivities recently observed in these new generations of membranes. Greater utilization of molecular modelling tools provides much greater insights in understanding transport behaviour in nanomaterials; however, true a priori nanomaterial design for membrane separation is still aspirational.

Industry applications for critical mineral recovery and energy devices now need to be realized for nanomaterial augmented membranes. Manufacturing advances have reduced the costs of synthesis of nanomaterials. However major challenges in large scale fabrication (especially those with complex architecture), chemical and mechanical robustness, and macroscopic design issues such as mass transfer/polarisation constraints remain. Examples of novel application of traditional and nontraditional techniques are now emerging for translation to industrial application in a variety of form factors.

More high value, unique applications for such membranes remain to be identified beyond highly commodified, large scale industrial applications where competitive alternatives ready exist. Demonstrated chemical and mechanical stability remain key attributes to acceptance in the chemical and energy industry, but less demanding applications may exist in other arenas. Integration of small amounts of nanomaterials into cost efficient manufacturing processes could provide entry to market where only expensive or non-optimal options are currently available.
