    Polyphenylene Sulfide PPS Fiber Membranes Resin Support Mesh ...
    Long-term durability of PPS (Polyphenylene Sulfide) membranes in alkaline electrolysis (ALK) is a key strength, thanks to PPS's inherent stability in hot, corrosive alkaline environments, with some commercial membranes claiming over 10 years life, though performance depends heavily on specific membrane composition (e.g., ZrO2/PSU coatings) and operating conditions, requiring advanced composite designs (like multi-layered PPS with polysulfone or cross-linked polymers) to balance gas separation, low resistance, and resistance to mechanical/chemical degradation for industrial success. 
    Key Factors Influencing Durability 
    • Material Composition: PPS provides the robust backbone, but adding materials like Zirconium Dioxide (
      ZrO2cap Z r cap O sub 2
      𝑍𝑟𝑂2
      ) and Polysulfone (PSU) creates composites (e.g., Zirfon) that enhance ion transport and barrier properties.
    • Operating Conditions: High temperatures (60-80°C) and concentrated KOH solutions challenge membranes, causing potential swelling, microcracking, or chemical attack.
    • Design & Structure: Differentiated pore structures (micro-nano) and cross-linked architectures (like PPS@PDA/PEIz/CC) improve mechanical strength and resistance to alkaline attack, leading to lower voltage and stable performance. 
    Performance & Lifespan Examples 
    • Commercial Membranes: Some advanced PPS-based separators (like Zirfon) are designed for >10 years of operation.
    • Research Examples: Modified PPS membranes have shown excellent stability, maintaining low resistance and voltage over hundreds or thousands of hours (e.g., 180-5000+ hours) in lab tests, resisting voltage increase. 
    Challenges & Solutions 
    • Challenge: Traditional PPS fabrics can have poor gas barrier performance.
    • Solution: Multi-layer structures incorporating microporous polysulfone layers improve gas barrier and prevent polymer detachment, boosting safety.
    • Challenge: Balancing low resistance with high gas selectivity.
    • Solution: Nanoparticle embedding and cross-linking create stable, hydrophilic structures with improved ion conductivity and gas separation. 
    In essence, PPS membranes are a durable choice for ALK electrolysis, but innovation in composite materials and structural design is crucial to unlock their full potential for industrial, long-term operation.
