Introduction to Antifouling Membranes

Therefore, findings in this work provide an effective antifouling modification strategy for microfiltration membranes and hold great potential for developing antifouling membranes for water treatment.

Polydopamine (PDA) particles (PDAPs) have been reported as a filler for constructing polymer composites, but because of their poor thermal stability, the use of PDAPs in high-temperature blend melt systems to construct antifouling membranes was rare.

In this work, antifouling membranes were fabricated by surface modification of a commercial anion exchange membrane with zwitterionic layers.

The development of antifouling membranes to separate oil/water emulsions in various environmental approaches is urgently needed.

This finding may help to develop antifouling membranes for AnMBR treating domestic wastewater.

Therefore, this study provides a simple and effective method of constructing stable and antifouling membranes for sustainable water treatment.

These results could be developed for several uses as in wound dressing applications, food packaging, and water treatment antifouling membranes.

Development of antifouling membranes for wastewater treatment technology can serve as an economic and efficient approach urgently demanded.

Because it is well documented that polydopamine coatings do not provide a long-lasting antifouling activity, poly(2-methacryloyloxyethyl phosphorylcholine) (polyMPC, Mn = 30 kDa) and succinimidyl-carboxymethyl-ester-terminated PEG ( Mn = 40 kDa) were codeposited while dopamine was polymerizing to generate antifouling membranes.

The development of antifouling membranes plays a vital role in the widespread application of membrane technology, and the hybridization strategy has attracted a significant amount of attention for antifouling applications.

As such, in the next section, we focus our attention on high-performance, antiwetting and antifouling membranes as potential solutions to address these challenges.

This work shows that carbon nanotubes can help to decrease roughness and polymer mobility on the surfaces of the membranes at the molecular scale, which represents a novel method to design antifouling membranes.

The development of antifouling membranes is always the basic approach to address the omnipresent bottlenecks of the membrane fouling.

Although a lot has been done on the making of antifouling membranes using PEGylated materials, numerous molecular design improvements can still be made on fine-tuning of both composition and chain length.

These findings would lead to a better understanding of antifouling demulsification mechanism and improved design of sustaining antifouling membranes for oil/water separation.

Finally, the ternary synergistic antifouling mechanisms among the zwitterionic membrane, electrolyte, and pollutant sodium alginates are discussed, which could be helpful for the rational design and preparation of new and highly efficient zwitterionic antifouling membranes.
