Electrospun nanofiber membranes for microplastic and nanoplastic removal from aquatic environments: a comprehensive review
AI summary Read the abstract
Tiny plastic bits (microplastics and even smaller nanoplastics) are turning up in our water supplies, and scientists are worried about what that means for our health. This review rounds up research on special filter materials made of ultra-fine fibers that can catch over 99% of these plastic particles from water using very little energy—no high-pressure pumps required, unlike systems like reverse osmosis. While the technology still needs real-world testing and safer manufacturing methods before it's ready for widespread use, it offers a promising, low-energy way to clean up drinking water and wastewater before plastic pollution reaches our taps.
The escalating contamination of aquatic ecosystems with microplastics (MPs) and nanoplastics (NPs) presents unprecedented environmental and health challenges worldwide. Electrospun nanofiber membranes have emerged as promising materials to address this crisis through their unique structural properties, tunable surface chemistry, and versatile removal mechanisms. This comprehensive review examines recent advances in electrospun fiber-based technologies for MP/NP removal, encompassing fundamental electrospinning principles, polymer selection strategies, surface modification approaches, and multi-functional designs. We critically analyze removal mechanisms, including size exclusion, electrostatic interactions, hydrophobic associations, and photocatalytic degradation, while evaluating performance metrics across diverse polymer systems ranging from synthetic polyacrylonitrile and poly(vinylidene fluoride) to bio-based cellulose and chitosan materials. Advanced functionalization strategies incorporating metal oxides, quaternary ammonium groups, and photocatalysts demonstrate remarkable synergistic effects, achieving removal efficiencies exceeding 99% for polystyrene particles of 0.1-25 µm in synthetic and doped natural water matrices under gravity-driven or low-pressure operation (0.04-0.7 bar). Reduced-but still > 85%-efficiencies are reported for sub-100 nm particles and for filtrations performed in real seawater and wastewater. The review addresses scalability challenges and environmental sustainability considerations aligned with the UN Sustainable Development Goals, including explicit linkage to SDG 6.3 wastewater-treatment targets, circular-economy principles, and the substantially lower energy footprint of gravity-driven electrospun membranes relative to reverse-osmosis systems. It also identifies critical research gaps requiring attention. Future directions emphasize integrated multi-functional platforms, green chemistry approaches, replacement of toxic solvents such as DMF by greener alternatives, melt electrospinning, and real-world validation to transition laboratory innovations toward practical implementation for safeguarding water quality and ecosystem health.

From Plastic Pollution to Remediation Solutions: Micro/Nanofiber-Based Strategies for Microplastic and Nanoplastic Removal
AI summary Read the abstract
Tiny plastic particles (microplastics and even smaller nanoplastics) are everywhere—in our water, food, and likely our bodies—and regular water treatment systems can't filter them out effectively. This review paper rounds up recent science on a promising fix: super-fine mesh-like materials (called micro/nanofibers) that can trap these plastic particles and, in some cases, help break them down into less harmful substances. While these filters aren't yet a fully solved, ready-to-use solution, this research points toward practical tools that could one day reduce our exposure to plastic pollution in drinking water.
A comprehensive insight into the removal of micro- and nanoplastics using novel nanomaterials
AI summary Read the abstract
Tiny plastic particles called microplastics and nanoplastics are showing up in our water supplies and can pose risks to human health, so scientists are searching for better ways to filter them out. This review paper rounds up existing research on cutting-edge materials, like specially engineered nanoparticles and filters, that can trap and remove these plastic particles more effectively than traditional water treatment methods. While these technologies are promising, they're still being refined, so widespread use in your local water treatment plant may take more time and research.
Direct filtration of microfibre-containing wastewater using nanofibre membranes: combined effects of mode of filtration and type of microfibre
AI summary Read the abstract
Scientists tested how tiny plastic fibers from clothes and textiles affect water treatment systems that remove these pollutants from wastewater. They found that different types of plastic fibers either help or hurt the cleaning process depending on the material and how the water flows through filters. This research is important because it could help improve systems that remove microplastics from our water supply before they reach rivers, oceans, and potentially our drinking water.
Evaluating nanofiber-based filter for domestic water filtration
AI summary Read the abstract
Scientists tested a new type of filter made from super-thin fibers to see if it could remove tiny plastic particles (smaller than what most home filters catch) from drinking water, using gravity alone rather than pumps. The best-performing filter blend removed nearly 88% of these microplastic stand-ins, though it let water through more slowly—showing a common trade-off between filtering well and filtering fast. This early-stage research is promising for developing better home water filters that could reduce our exposure to microplastics, but more work is needed before these filters are ready for household use.
