Summary

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.
