Proton Exchange Membranes Based on POSS

Two kinds of proton exchange membranes (PEMs) containing POSS are designed and prepared, one is sulfonated poly (ether ether ketone) (SPEEK)/bisphenol S diglycidyl ether (DEBS)/POSS hybrids with the semi-interpenetrating polymer networks (IPNs) structure and the other is sulfonated polyimides (SPI)/POSS hybrids with cross-link structure. IPNs should be more contributed to improve the proton conductivities of PEMs than cross-link structure.
