"Chemical Equation Presented" Segregation is a key theme of this film: Poly(arylene ether sulfone ketone) multiblock membranes containing highly sulfonated hydrophilic blocks were prepared by postsulfonation. High local concentrations of sulfonic acid groups within the hydrophilic blocks enhanced the phase separation of the two block types (see picture), and the high interconnectivity of the rodlike hydrophilic aggregates led to high proton conductivity even at low humidity.
