Summary
This review explores eight physical methods for fabricating graphene oxide (GO) membranes. It classifies techniques into small-scale and large-scale approaches, emphasizing scalable methods for industrial GO membrane commercialization.
Area of Science:
- Materials Science
- Chemical Engineering
- Nanotechnology
Background:
- Graphene oxide (GO) exhibits significant potential for separation membranes.
- Industrial adoption of GO membranes is hindered by challenges in large-scale production.
Purpose of the Study:
- To review physical methods for GO membrane fabrication.
- To highlight scalable techniques for commercializing GO membranes.
Main Methods:
- Classified eight physical fabrication methods into small-scale (vacuum filtration, pressure-assisted filtration, spin coating, dip coating, drop-casting) and large-scale (spray coating, bar/doctor blade coating, slot die coating) approaches.
- Distinguished between batch-unit and continuous fabrication processes.
Main Results:
- Large-scale, continuous fabrication methods are less limited by equipment size compared to small-scale methods.
- Scalable approaches are crucial for overcoming commercialization barriers.
Conclusions:
- The review provides a technical overview of GO membrane preparation.
- Focusing on scalable processes is key to advancing the commercial viability of GO membranes.
