Abstract
Polymer membranes are an energy-efficient separation technique useful for liquids, gases, and biologics. Traditional membranes are manufactured using a solvent-based system that is very scalable but relies on the use of large volumes of toxic solvents. An alternative manufacturing route is melt processing, which eliminates organic solvents. Micro- and ultra-filtration applications are well suited for melt-manufactured membranes with strong separation performance demonstrated that is comparable to solvent-based manufacturing techniques. Melt manufacturing of membranes for gas separations remains difficult, however. New routes of membrane design are proposed, allowing for melt manufacturing to create membranes for a more complete spread of applications.
期刊介绍：
Current Opinion in Chemical Engineering is devoted to bringing forth short and focused review articles written by experts on current advances in different areas of chemical engineering. Only invited review articles will be published.
The goals of each review article in Current Opinion in Chemical Engineering are:
1. To acquaint the reader/researcher with the most important recent papers in the given topic.
2. To provide the reader with the views/opinions of the expert in each topic.
The reviews are short (about 2500 words or 5-10 printed pages with figures) and serve as an invaluable source of information for researchers, teachers, professionals and students. The reviews also aim to stimulate exchange of ideas among experts.
Themed sections:
Each review will focus on particular aspects of one of the following themed sections of chemical engineering:
1. Nanotechnology
2. Energy and environmental engineering
3. Biotechnology and bioprocess engineering
4. Biological engineering (covering tissue engineering, regenerative medicine, drug delivery)
5. Separation engineering (covering membrane technologies, adsorbents, desalination, distillation etc.)
6. Materials engineering (covering biomaterials, inorganic especially ceramic materials, nanostructured materials).
7. Process systems engineering
8. Reaction engineering and catalysis.
