TECHNICAL SPECIFICATION
CONSTRUCTIONNo PPS Mesh Required Mesh-Free Design
IONZERA is the first commercial AWE separator to eliminate PPS mesh reinforcement entirely. The self-supporting PSU-TiO₂-GO nanocomposite achieves superior mechanical strength while providing more uniform pore distribution and lower manufacturing cost.

The Problem with Mesh-Reinforced Membranes
Zirfon PERL UTP 500 and similar conventional AWE separators use PPS (polyphenylene sulfide) mesh fabric as a structural reinforcement layer embedded within the membrane. While this approach provides mechanical support, it introduces several disadvantages: the PPS mesh is one of the most expensive components in the membrane, it creates a non-uniform pore structure where the mesh fibers disrupt the ceramic-polymer matrix, and it adds supply chain complexity with limited global PPS mesh suppliers.
IONZERA takes a fundamentally different approach by engineering a self-supporting porous composite that achieves superior mechanical strength (2.7 MPa vs ~2.0 MPa) without any mesh reinforcement.
Benefits of Mesh-Free Construction
Eliminating the PPS mesh provides multiple interconnected advantages:
How IONZERA Achieves Structural Integrity Without Mesh
IONZERA's mechanical strength comes from the nanocomposite material itself rather than an external reinforcement. The polysulfone (PSU) polymer matrix provides the structural backbone, TiO₂ nanoparticles act as distributed reinforcing fillers, and graphene oxide nanosheets — with their exceptional tensile strength and high aspect ratio — create an internal reinforcement network far more effective than a macroscopic mesh.
