Researchers at the University of Bath developed a renewable, bio-based polymer membrane that effectively captures and holds toxic perfluorooctanoic acid (PFOA) from water. The nanofibers in the membrane structurally reorganize and tighten when exposed to water, creating a net-like mechanism that traps stubborn "forever chemical" pollutants directly inside the polymer network.
