Review evaluates eco-friendly bio-based polymers for membrane distillation water purification, highlighting trade-offs between degradability, membrane stability, and desalination performance.
Membrane distillation (MD) enables water purification under moderate conditions but relies heavily on fluorinated, non-biodegradable membranes, which raise serious environmental concerns. This Review evaluates four categories of eco-friendly bio-based polymers for MD, linking physicochemical properties, thermal stability, and degradability to operational performance. Comparative analysis under practical conditions highlights relationships between polymer degradability, process stability, water flux, salt rejection, and ecological impact, while identifying key challenges for large-scale adoption.
