Advantages

Higher rejection at alkaline pH

PFOA becomes more ionized at alkaline pH, increasing electrostatic repulsion and improving rejection.

Resists nanoplastics fouling

Even when nanoplastics form a cake layer and enhance concentration polarization, the membrane maintains PFOA rejection with accumulation tuned by particle surface chemistry.

Applications

• Water treatment membrane separation：Removes PFOA from complex water while resisting nanoplastic fouling.
• Antifouling functional membranes：Maintains high rejection in the presence of nanoplastics.
