TECHNICAL SPECIFICATION

MATERIAL

Three-Component Nanocomposite Architecture PSU-TiO₂-GO

IONZERA's membrane material is a purpose-engineered nanocomposite where polysulfone provides the structural matrix, TiO₂ nanoparticles add hydrophilicity and photocatalytic protection, and graphene oxide nanosheets enhance ion transport and mechanical strength.

Three Components, Synergistic Performance

IONZERA's membrane material is a carefully engineered nanocomposite where each component plays a specific and complementary role. Polysulfone (PSU) provides the polymer matrix — a chemically resistant, mechanically tough backbone stable in concentrated KOH. Titanium dioxide (TiO₂) nanoparticles serve as hydrophilic fillers that attract electrolyte and provide photocatalytic protection. Graphene oxide (GO) nanosheets create additional ion transport pathways and reinforce the mechanical structure.

This three-component system delivers capabilities that Zirfon's simpler ZrO₂-in-polymer architecture cannot achieve, including lower ionic resistance, better wettability, photocatalytic self-protection, and mesh-free mechanical strength.

Why PSU Over Other Polymers?

Polysulfone was selected as the matrix polymer for several critical reasons:

Excellent chemical stability in concentrated KOH electrolyte — no degradation under standard AWE conditions
High glass transition temperature providing dimensional stability during operation
Good processability for creating controlled pore structures through phase inversion
Strong interfacial bonding with both TiO₂ nanoparticles and GO nanosheets, ensuring nanocomposite integrity

Comparison with Zirfon's ZrO₂ Approach

Zirfon PERL uses zirconium dioxide (ZrO₂) as its sole ceramic filler. While ZrO₂ provides hydrophilicity and chemical stability, it is a single-function material. IONZERA's dual-filler approach (TiO₂ + GO) delivers multifunctional performance: TiO₂ provides hydrophilicity plus photocatalytic protection against organic degradation, while GO adds ion transport enhancement plus mechanical reinforcement. The result is a material system that outperforms ZrO₂ across multiple dimensions simultaneously.
