Polysulfone resin is primarily used to produce ultrafiltration and reverse osmosis membranes. As an important type of water treatment membrane, polysulfone membranes exhibit inherent hydrophobicity, making them prone to organic fouling (e.g., by proteins) during separation processes, which compromises permeability and service life. Various modification methods have been developed to enhance performance, including surface coating, grafting polymerization, and interfacial polymerization. In contrast, polyethersulfone (PES) membranes demonstrate superior hydrophilicity, flux performance, chemical stability, inertness, alkaline pH tolerance, and high pharmaceutical compatibility.

?

Polyethersulfone (PES), as a high-performance engineering plastic, has emerged as a core material in advanced separation membranes due to its exceptional thermal resistance (glass transition temperature ~225°C), chemical stability (resistance to acids, alkalis, and organic solvents), and mechanical strength. In reverse osmosis (RO) applications, PES serves as a porous support layer formed via phase inversion, providing mechanical support for polyamide active layers while offering significantly better chlorine resistance than conventional polysulfone (PSU), thereby extending RO membrane lifespan in desalination systems. For ultrafiltration (UF) and microfiltration (MF), PES membranes with tunable pore sizes (UF: 1-100nm; MF: 0.1-10μm) and hydrophilic modification potential are widely adopted in biopharmaceuticals (vaccine purification, protein separation), food & beverage (dairy sterilization, juice clarification), and semiconductor ultrapure water production - their low protein adsorption markedly reduces fouling risks. Sulfonated or amphiphilic copolymer-modified PES enables precise rejection of divalent ions (Ca2?, Mg2?) and dye molecules in nanofiltration (NF), proving particularly effective for industrial wastewater zero-liquid-discharge and resource recovery.

?

In biomedical applications, PES's outstanding biocompatibility (ISO 10993 certified) makes it the material of choice for hemodialysis membranes, extracorporeal membrane oxygenation (ECMO), and tissue engineering scaffolds. For instance, hollow-fiber PES dialysis membranes with optimized pore sizes (3-5nm) selectively remove uremic toxins (e.g., β2-microglobulin) while retaining albumin; heparin-grafted PES surfaces further inhibit thrombosis and enhance hemocompatibility. PES also shows promise in emerging fields like gas separation (CO?/N? selectivity) and fuel cell proton-exchange membranes, though requires nanomaterial blending (e.g., graphene, MOFs) to improve conductivity or selectivity.

?

Despite limitations like higher costs (~1.2-1.5× PSU) and UV instability, PES's comprehensive performance sustains its irreplaceable role in demanding medical and industrial applications. Future advancements will focus on green solvent-based processing (e.g., ionic liquids), antifouling bioinspired coatings (polydopamine modification), and stimuli-responsive smart membranes (temperature/pH-sensitive), expanding its applications in precision medicine and carbon-neutral technologies.

The development of polyethersulfone (PES) for membrane applications exhibits dual characteristics of being technology-driven and demand-pulled. From a technological perspective, PES has become a core material for high-end separation membranes due to the exceptional properties endowed by its ether and sulfone groups in the molecular structure (including heat resistance up to 225°C, chemical corrosion resistance, and high mechanical strength). Technological evolution is primarily manifested in three aspects: first, the refinement of membrane-forming processes, where optimization of techniques like non-solvent induced phase separation (NIPS) and vapor-induced phase separation (VIPS) enables precise control of pore size distribution from microfiltration (0.1-10μm) to ultrafiltration (1-100nm); second, the diversification of modification technologies, including surface grafting (e.g., PEG modification for enhanced hydrophilicity), blending modification (e.g., adding nano-TiO? to improve antifouling properties), and chemical crosslinking (to enhance solvent resistance); third, the cross-industry integration of applications, expanding from traditional water treatment to biomedicine and new energy sectors. This technological iteration has significantly improved PES membrane stability under extreme conditions, with performance retention rates exceeding 90% in strong acid/alkali environments or high-temperature steam sterilization - far superior to conventional polymer membranes.

Market drivers stem from the dual resonance of policy and demand factors. On the policy front, increasingly stringent global water resource regulations (e.g., China's "Water Ten Plan" and the EU Industrial Emissions Directive) and upgraded medical standards (e.g., FDA's new biocompatibility requirements for dialysis membranes) are mandating the transition of the separation membrane industry toward high-performance materials. Demand-side growth shows structural characteristics: in water treatment, desalination capacity expansion (particularly in the Middle East and Asia-Pacific) and industrial wastewater "zero discharge" policies are driving RO and NF membrane demand; in biomedicine, global aging is fueling 6-8% annual growth in hemodialysis markets, while the explosive development of mRNA vaccines and other biologics is stimulating UF purification membrane demand; emerging fields like hydrogen fuel cell proton-exchange membranes and lithium battery separator coatings are creating new growth spaces for PES. Although higher material costs limit penetration in some mid-to-low-end applications, PES membranes' irreplaceability in high-end markets (e.g., mandatory ISO 10993 certification in medical fields) and lifecycle cost advantages (30-50% extended replacement cycles) sustain their premium positioning during industrial upgrading. Over the next 3-5 years, with the maturation of green manufacturing processes (e.g., solvent-free membrane formation) and breakthroughs in composite membrane technologies, PES membranes are expected to establish new growth frontiers in cutting-edge fields like carbon capture and organ-on-a-chip applications.
