SEPARATOR & MEMBRANE COATINGS

eGraphene coatings transform separators and ion-exchange membranes. As the industry moves beyond PFAS-based membranes, eGraphene offers an alternative.

Across batteries, fuel cells, and redox-flow systems, separators and membranes are vital for safety and performance — yet PFAS-based polymers today face tightening EU and US regulations, pushing the industry to find durable, safe, and sustainable alternatives.

Redox-Flow Systems

eGraphene coatings maintain ionic conductivity, minimize crossover of unwanted species, and enhance chemical resistance, extending membrane lifetime and enabling PFAS-free operation in harsh electrochemical environments.

Fuel Cells

As a conductive, protective layer, eGraphene improves barrier performance towards unwanted species, mechanical durability, and long-term stability — enabling next-generation fuel cell membranes.

INTRODUCING
eGRAPHENE

eGraphene — a few-layer, electrochemically exfoliated, and functionalized graphene made by a patented water-based process — is available as ready-to-use formulations for thin membrane coatings. It forms an ultra-thin, chemically stable, and conductive layer that enhances durability, conductivity, and chemical resistance — enabling high-performance, and even PFAS-free membranes.
