Research Progress of Marine Anti-Fouling Coatings

Coatings, Год журнала: 2024, Номер 14(9), С. 1227 - 1227

Опубликована: Сен. 23, 2024

The extended immersion of ships in seawater frequently results biofouling, a condition characterized by the accumulation marine organisms such as barnacles and algae. To combat this issue, application anti-fouling coatings to hull surfaces vessels has emerged one most effective strategies. In response increasing global emphasis on environmental sustainability, there is growing demand for that not only demonstrate superior efficacy but also adhere stringent standards. traditional use organotin-based self-polishing coatings, known their high toxicity, been prohibited due concerns. Consequently, progressive shift toward development environmentally friendly coatings. This paper reviews toxicity limitations associated with conventional It provides comprehensive overview recent advancements field, including novel low surface energy biomimetic nanostructured each leveraging distinct mechanisms. evaluates composition performance these emerging identifies key technical challenges remain unresolved. proposes multi-faceted approach addressing challenges, suggesting potential solutions enhancing effectiveness compatibility technologies. forecasts future research directions trajectories emphasizing need continued innovation achieve both sustainability performance.

Construction of Waste Paper-Chitosan-Based Membranes with pH-Tunable Surface Charge for Efficient Separation of Oil-in-Water Emulsion and Dye

ACS Sustainable Chemistry & Engineering, Год журнала: 2024, Номер 12(29), С. 10854 - 10868

Developing a cost-effective, versatile, biodegradable, and biobased membrane is crucial for the sustainable treatment of complex wastewater. In this work, multifunctional was fabricated from polydopamine-modified waste paper (WP@PDA) hydrothermal carbonized chitosan (HTCC), through simple vacuum filtration. This demonstrated high efficiency in separating oil-in-water emulsions allowed situ dye removal under controllable pH conditions. The results showed that as-prepared WP@PDA/HTCC exhibited superhydrophilic, oil-resistant, pH-tunable surface charge features. With weight ratio WP@PDA HTCC 6:2, it displayed optimal mechanical properties structural stability aqueous environments. As expected, achieved outstanding performance different at 0.05 bar followed by satisfactory flux approximately 2400 L m–2 h–1 bar–1 separation around 99.5%. Furthermore, abundant functional groups on also endowed with capability both cationic anionic dyes. It can efficiently eliminate methyl orange (MO) methylene blue (MEB) dye-contaminated wastewater mainly electrostatic interactions. Even after filtering 1550 MO 1650 MEB simulated using membrane, its efficiencies toward dyes remained above 90.0%. Interestingly, WP@PDA/HTCC-1 presented bidirectional controlled behaviors mixture suitable solution due to feature. Most importantly, excellent reusability resistance against harsh chemical corrosions without losing properties. Therefore, could be promising material treatment.

Removal of Plastics from Micron Size to Nanoscale Using Wood Filter

Materials, Год журнала: 2024, Номер 17(6), С. 1361 - 1361

Опубликована: Март 16, 2024

Plastic pollution, particularly microplastic (MP) and nanoplastic (NP) has become a significant concern. This study explores the use of porous wood for filtration to remove MPs NPs investigates their removal mechanisms. Undecorated fir with thickness 4 mm achieves 91% rate model polystyrene (PS) (2.6 μm) at water flux 198 L/m2h. However, its separation performance (255.8 50.9 nm) is poor. It also shows that (coniferous wood) higher PS than poplar (hard wood). With poly dimethyl diallyl ammonium chloride (PDDA) modification, both are effectively removed, NPs’ increasing from <10% 90% PDDA/wood. Characterization results reveal size-exclusive interception dominates micron-sized particles, electrostatic interaction crucial nanosized particles. Additionally, intercepted have been used as strong binder hot-pressed remarkably enhance mechanical properties wood, suggesting novel recycle utilization discarded filters. Overall, this renewable material offers simple solution tackling MP/NP pollution.
