Anion exchange membranes (AEMs) play a critical role in clean energy devices, and optimizing their performance requires deeper understanding of morphology-performance relationships. This study investigates ABC triblock terpolymer AEMs to explore how domain continuity influences hydroxide conductivity, water uptake, dimensional stability. High molecular weight terpolymers were synthesized through the controlled vinyl-addition polymerization norbornene monomers functionalized with alkyl, benzyl, or bromobutyl substituents. Morphology was systematically varied across series without significantly changing ion capacity (IEC) polymer by adjusting alkyl/benzyl block length ratio. Solution-cast films exhibited either 2D-continuous lamellar 3D-co-continuous network phase morphologies, largely retained after cationic functionalization. domains demonstrated superior performance, including enhanced stability competitive conductivities up 84 mS/cm at 25 °C 131 80 °C. work highlights self-assembly can be leveraged investigate relationships achieve highly conductive, durable AEMs.

Biofouling in membrane filtration systems poses significant operational challenges, leading to decreased permeate flux. The aim of this work was study the anti-biofilm properties new nanofiltration membranes produced via layer-by-layer, LBL, assembly by coating a polyvinylidene fluoride (PVDF) support with polyethylenimine (PEI) and poly(acrylic acid)/graphene oxide (PAA-GO) mixture. were characterized according contact angle, scanning electron microscopy (SEM), atomic force their Z-potential. Biofilm quantification characterization carried out using crystal violet staining SEM, while bacterial viability assessed colony-forming units. three bilayers ((PAA-PEI)
