Special Issue Information

Dear Colleagues,

The Special Issue of Polymers titled “Application of Natural-Based Polymers in Water Treatment” delves into employing natural-based polymers to tackle challenges related to water treatment. This Special Issue aims to provide a platform for the dissemination of novel research on the preparation, characterization, and application of natural-based polymers such as cellulose, lignin, alginate, starch, chitin, chitosan, pectin, gelatin, and their composites for the removal of different contaminants from water.

The capabilities of engineering, such as developing advanced materials, will expand their practical applications to treat water while reducing their environmental impacts.

This Special Issue not only offers a glimpse of the most innovative studies on water treatment but also promotes collaboration between material scientists, chemists, and environmental engineers.

This Special Issue emphasizes the recent advancements in exploiting natural-based polymers and their composites for the development of cutting-edge and next-generation solutions for water treatment.

Abstract
Soil ruins hold historical significance and serve as witnesses to past civilizations. High temperatures cause soil moisture to evaporate and soil to shrink, leading to cracking issues and making preservation a global challenge. P(AA-AM-AMPS) (Acrylic acid -Acrylamide-2-Acrylamide-2-methy-propenesulfonic acid) composites solve this problem by [...] Read more.
Soil ruins hold historical significance and serve as witnesses to past civilizations. High temperatures cause soil moisture to evaporate and soil to shrink, leading to cracking issues and making preservation a global challenge. P(AA-AM-AMPS) (Acrylic acid -Acrylamide-2-Acrylamide-2-methy-propenesulfonic acid) composites solve this problem by combining absorbent materials with loess. In this study, P(AA-AM-AMPS) was prepared using a solution method. The water absorption, water retention, air permeability, and compressive strength of P(AA-AM-AMPS) in loess were studied. The results show that after adding P(AA-AM-AMPS) to loess, there is no obvious color difference compared with the blank sample, and the air permeability of the reinforced loess is basically the same as that of the blank soil. After aging resistance tests, the surface cracking of soil clods is significantly reduced compared to that of the blank samples, and their compressive strength improved from 1.8 N/mm2 to 2.6 N/mm2.

The development of ultrafiltration (UF) polymeric membranes with high flux and enhanced antifouling properties bridges a critical gap in the polymeric membrane fabrication research field. In the present work, the preparation of novel PES membranes incorporated with carrageenan (CAR), which is a natural polymer derived from edible red seaweed, is reported for the first time. The PES/CAR membranes were prepared by using the nonsolvent-induced phase separation (NIPS) method at 0.1–4.0 wt.% CAR loadings in the casting solutions. The use of dimethylsulfoxide (DMSO), which is a bio-based and low-toxic solvent, is reported. Scanning electron microscopy, atomic force microscopy, water contact angle, porosity, and zeta potential measurements were used to evaluate the surface morphology, structure, pore size, hydrophilicity, and surface charge of the prepared membranes. The filtration performance of PES/CAR membranes was tested with bovine serum albumin (BSA) solutions. It was shown that CAR incorporation in the casting solutions notably increased hydrophilicity, porosity, pore size, surface charge, and fouling resistance of the prepared membranes compared with plain PES membranes due to the hydrophilic nature and pore-forming properties of CAR. The PES/CAR membranes showed a significant reduction in irreversible and total fouling during filtration of BSA solutions by 38% and 32%, respectively, an enhancement in the flux recovery ratio by 20–40%, and an improvement in mechanical properties by 1.5-fold when compared with plain PES membranes. The findings of the present study indicate that CAR can be used as a promising additive for the development of PES UF membranes with enhanced properties and performance for water treatment applications.
