Special Issue Information

Dear Colleagues,

Owing to the rapid growth of the global population and industrialization, the human race will inevitably suffer from a catastrophic water shortage if no effort is made to search for alternative, safe water resources. Hence, researchers have conducted intensive studies investigating the potential to reclaim wastewater and purify stormwater or seawater as water sources for municipal applications via various membrane technologies.

Membrane separation technology, which utilizes polymeric membranes, is the most sustainable and effective way to solve this vital problem due to its advantages in terms of efficiency and energy conservation. As the polymers utilized in the production of membranes can be synthesized easily, the optimal membrane performance can be achieved in a chosen process environment. Various new membrane types have been developed in membrane technology, such as nanocomposite, photocatalytic, adsorptive, and biomimetic membranes. Novel polymeric materials, including dendronized, ionic, and solvent-resistant polymers, have also been reported to improve the properties of membranes.

This Special Issue is focused on the latest fundamental and applied research in polymeric membrane technologies, including, but not limited to, the synthesis of novel membrane materials, membrane modifications, and advanced membrane processes.

We hereby invite you to submit research articles or reviews of the latest research that could present innovative findings and breakthroughs in polymeric membrane science.

The development of environmentally friendly technology is vital to effectively address the issues related to environmental deterioration. This work integrates ZnO-decorated MoS2 (MZ) to create a high-performing PVDF-based PVDF/MoS2-ZnO (PMZ) hybrid polymer composite film for sonocatalytic organic pollutant degradation. An efficient synergistic combination of MZ was identified by altering the ratio, and its influence on PVDF was assessed using diverse structural, morphological, and sonocatalytic performances. The PMZ film demonstrated very effective sonocatalytic characteristics by degrading rhodamine B (RhB) dye with a degradation efficiency of 97.23%, whereas PVDF only degraded 17.7%. Combining MoS2 and ZnO reduces electron–hole recombination and increases the sonocatalytic degradation performance. Moreover, an ideal piezoelectric PVDF polymer with MZ enhances polarization to improve redox processes and dye degradation, ultimately increasing the degradation efficiency. The degradation efficiency of RhB was seen to decrease while employing isopropanol (IPA) and p-benzoquinone (BQ) due to the presence of reactive oxygen species. This suggests that the active species •O2 and •OH are primarily responsible for the degradation of RhB utilizing PMZ2 film. The PMZ film exhibited improved reusability without substantially decreasing its catalytic activity. The superior embellishment of ZnO onto MoS2 and effective integration of MZ into the PVDF polymer film results in improved degrading performance. Full article
