“…The current research progress in acid-tethered polymers is closely related to the controlled synthesis of high-precision polymers with tailor-made monomers. − To date, various types of acid moieties have been added to several polymers with tunable glass transition temperatures ( T g ) − and polarities. − This has enabled the high-yield preparation of proton-conducting polymers with linear diblock, ,,− triblock, , pentablock, , and comb shapes . Therefore, the exploration of the structure–transport relationship became possible.…”
