POLYMER ELECTROLYTE MEMBRANES (PEMS) BASED ON IMIDAZOLE RING TERMINATED FLEXIBLE BRANCHES GRAFTED ON HYBRID INORGANIC-ORGANIC POLYMERS

摘要

A composition of matter comprises a polymer network, including silicon atoms and oxygen atoms, a first organic side-chain attached to at least some silicon atoms within the polymer network comprising a flexible linking group and a terminal group, the terminal group including at least one atom providing a lone pair of electrons. The composition of matter can be used to form a proton-conducting membrane. In illustrative examples, the polymer network can be an organic-inorganic hybrid network and the terminal group can includes a nitrogen-containing heterocycle.
