Intrapolymer Heck reaction for proton conductive ladder-type aromatic block copolymers†
Abstract
A novel polymer synthetic method, the intrapolymer Heck reaction, provided ladder-type ionomer membranes with excellent proton conductivity (221 mS cm−1 at 80 °C and 90% relative humidity) and mechanical strength over a wide range of humidity (ca. 0–90% relative humidity) at 80 °C.
