Abstract
Chemical cross-linking in membrane fabrication aims to face limitations of polymer membranes, including poor chemical resistance, low mechanical stability, swelling, etc. Typical cross-linkers do not fit green chemistry and sustainable principles due to their toxicity. Thus, this article discusses the successful application of green cross-linkers (including organic acids — citric, gallic, ferulic, and tannic acid, calcium chloride, deep eutectic solvents, pectin) and less toxic substances in polymer membranes (including biopolymeric ones based on chitosan or cellulose) fabrication. This article also mentions how to make it ‘greener’. Important areas for these developments include food biopackaging materials, 3D printing materials, and biomedical items.
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.
