TECHNICAL SPECIFICATION
STRUCTURALHigh Porosity for Maximum Ion Conductivity 55–65% Porosity
Porosity determines how much of the membrane is available for ion transport. IONZERA's 55–65% porosity — 10–15% higher than Zirfon — provides more electrolyte-filled channels for hydroxide ions, contributing to its dramatically lower area resistance.

Porosity and Its Role in Ion Conductivity
In a porous separator membrane, ions do not travel through the solid polymer-ceramic material — they travel through the electrolyte-filled pores. Porosity (the volume fraction of pores) therefore directly determines how much of the membrane cross-section is available for ion transport. Higher porosity means more electrolyte channels and lower ionic resistance.
IONZERA achieves a porosity of 55–65%, compared to 50–55% for Zirfon PERL UTP 500. This 10–15% relative increase in pore volume, combined with optimized pore size and GO-enhanced transport, contributes to IONZERA's dramatically lower area resistance.
Porosity Without Compromising Structure
Increasing porosity typically weakens a membrane mechanically — more pores mean less solid material to carry loads. IONZERA overcomes this trade-off through its nanocomposite material design:
Connected Pore Network for Efficient Transport
High porosity alone is not sufficient for low ionic resistance — the pores must also be well-connected to form continuous transport pathways from one membrane face to the other. IONZERA's phase inversion manufacturing process creates an interconnected pore network with high tortuosity efficiency, meaning ions can travel through the membrane via relatively direct pathways rather than long, winding routes.
