Nafionlike
Nafionlike refers to polymers and composites designed to emulate Nafion's essential properties: a fluorinated, chemically stable backbone with sulfonic acid groups forming hydrated hydrophilic channels that support proton transport. They function as proton exchange membranes in electrochemical devices such as fuel cells and electrolyzers. They are not limited to a single material; many polymers and composites are described as Nafionlike.
Design and composition: Nafion itself is a perfluorosulfonic acid polymer (PFSA). Nafionlike materials include PFSA-based copolymers,
Performance and challenges: Nafionlike membranes typically exhibit high proton conductivity under humidified conditions, good chemical resistance,
Applications and research directions: used as PEMs in polymer electrolyte fuel cells, proton-exchange membranes for electrolysis,
