Side-Chain Sulfur-Enhanced Hydrogen-Bonding Networks in Sulfonated Poly(arylene alkane)s for High Proton Conductivity
Sulfonated poly(arylene alkane)s with all-carbon aromatic backbones are promising proton exchange membrane (PEM) materials, but their high conductivity generally relies on a high degree of sulfonation, which often causes excessive water swelling and compromises dimensional stability. Here, we report a side-chain desi...
