New ultrafiltration (UF) membrane made with a new polymer material for long-lasting rejection performance, Neophil®
AI summary Read the abstract
A new ultrafiltration membrane was developed using an amphiphilic block copolymer anchored in a PVDF matrix, maintaining long-term rejection of particles including microplastics, bacteria, and viruses even after accelerated aging. The Neophil membrane technology offers improved durability compared to conventional filtration membranes used in water treatment.
Abstract This paper focuses on the development of a new membrane, named Neophil®, with durable performance using a new amphiphilic nanostructured dibloc-copolymer (BCP) composed of one hydrophilic bloc and one hydrophobic bloc which is anchored deeply and permanently in the polymer matrix (PVDF, Kynar resin Arkema) of the membrane. Compared to conventional membranes, particle rejections (suspended solids, microplastics, bacteria and viruses) have been shown to be maintained through accelerated ageing experiments. In this paper, this new membrane technology is described and its durability is demonstrated and compared with other membranes of the market.

AI summary Read the abstract
Scientists have engineered a new water filter material that better resists clogging from microplastics, tiny plastic particles increasingly found in our water supplies. By adding special particle coatings to filtration membranes, the improved filters let water flow through more easily and stay cleaner for longer, with one version recovering 93% of its filtering power after use compared to just 55% for standard filters. This matters because more effective, longer-lasting water treatment technology could help remove microplastic pollution before it reaches our drinking water, though this research was done in lab conditions and hasn't yet been tested in real-world treatment plants.

Scientists combined two special crystal materials (called MOFs) to create a new water filter membrane that lets water flow through much faster while still blocking 94% of contaminants like microplastics and proteins. This upgraded filter also resists clogging better than standard filters, which matters because clogged filters need more frequent replacement and can let unwanted particles slip through over time, both important factors for making clean water access more reliable and affordable.

Researchers developed a new type of water filter membrane that can remove over 99% of nanoplastics from wastewater while maintaining high water flow. The membrane uses metal-organic framework nanoparticles that repel plastic particles through electrical charges and physical filtering. This technology could help prevent nanoplastics, which are too small for conventional filters, from reaching drinking water sources.

Researchers created an advanced membrane filter using metal-organic framework nanoparticles that removed over 99% of nanoplastics from water while maintaining high water flow rates. The membrane resisted fouling and worked reliably across multiple cycles and different water conditions. This type of technology could improve wastewater treatment plants' ability to prevent nanoplastics from reaching drinking water supplies.

Scientists engineered a new type of water filter membrane that resists clogging from nanoplastics, tiny plastic particles too small to see that are increasingly found in drinking water. By coating the filter with a special material that switches its electrical charge depending on water conditions, they created a self-cleaning surface that blocked over 95% of nanoplastics while staying easier to rinse clean than standard filters. This matters because more effective, longer-lasting water filters could help reduce our exposure to nanoplastics, which scientists are still studying for potential health effects.
