Biomimetic 3D Prototyping of Hierarchically Porous Multilayered Membranes for Enhanced Oil–Water Filtration

ACS Applied Materials & Interfaces, Год журнала: 2025, Номер unknown

Опубликована: Янв. 23, 2025

This study introduces a biomimetic approach to 3D printing multilayered hierarchical porous membranes (MHMs) using Direct Ink Writing (DIW) technology. Fabricated through fast layer-by-layer process with varying concentrations of pore-forming agents, the produced MHMs mimic pore structure and filtration capabilities natural soil systems. As result, 3D-printed achieved an impressive oil rejection rate 99.02% demonstrated exceptional reusability, maintaining flux recovery ratio 99.48% even after hours continuous filtration. Moreover, exhibit superior architecture mechanical integrity compared traditional flat sheet single-layered membranes. presents significant advancement for scalable customized multilayer tailored porosity high-performance properties. The simplicity, versatility, cost-effectiveness presented manufacturing method offer pathway advanced design on-demand membrane production.

Low Shrinkage and Robust Polyimide/Ultrafine Glass Fiber Aerogel for Efficient Heat Resistance and Oil/Water Separation

ACS Applied Polymer Materials, Год журнала: 2025, Номер unknown

Опубликована: Янв. 9, 2025

Polyimide (PI) aerogels have attracted a great deal of attention due to their low density and excellent heat resistance. However, PI produce large, irregular shrinkage during the thermal imidization process, resulting in decreased porosity strength. In this work, silane coupling agent-modified ultrafine glass fibers (mUGF) were mixed with polyamide acid solution, followed by freeze-drying prepare PI/mUGF aerogels. As inorganic reinforced phase, mUGF high aspect ratio can significantly enhance skeleton aerogel, reducing its volume avoiding collapse porous structure imidization. The aerogel exhibits (0.059 g/cm3), (18%), good mechanical properties, stability insulation (thermal conductivity as 31.4 mW/m·K at room temperature, 55.9 300 °C). Additionally, also shows adsorption properties (pump oil temperature: 24 g/g; 200 °C: 17 g/g) structural stability, which be used adsorb oils organic solvents from polluted water. These findings promote design development low-shrinkage robust for oil/water separation insulation.

Sandwiched Copper Foam with Symmetrical Wettability for Direction-Independent Fog Collection

Langmuir, Год журнала: 2025, Номер unknown

Опубликована: Фев. 27, 2025

The Janus membrane demonstrates its advantages in timely drainage and directional water transport properties for efficient fog collection, which helps alleviate global shortages. However, the direction-dependent collection inefficient limit widespread application. Herein, a single-layered sandwich-structured copper foam that features superhydrophilic inner layer double-deck external hydrophobic layers is prepared by simple method. This innovative architecture direction-independent harvesting capabilities through synergistic integration of symmetric wettability gradients robust structural integrity. Such sandwiched shows superiority rapid can quickly regenerate fresh outer surface as well unidirectional properties. property combined with benefits continuous better performance compared to conventional membranes. Clearly, development such enables effective durable droplets environments dynamically changeable winds. Overall, this work provides new idea fabrication advanced materials collection.
