Influence of rigid–soft domains on proton conduction and microstructure in block copolymer membranes
Abstract
at 50% relative humidity and 1 bar vapor pressure. Structural analysis revealed planar, porous surfaces and supported the role of proton hopping as the dominant conduction mechanism, with activation energies in the range of 0.08-0.50 eV. These findings highlight how rigid-soft molecular design can balance stability and conductivity, making such membranes promising candidates for use as separators in hydrogen or methanol fuel cells.
