With the help of nuclear magnetic resonance (NMR) and quasi-elastic neutron scattering (QENS) we have carried out dynamic studies of Ormosil membranes presenting protonic conductivity properties. These nanocomposite hybrid materials prepared by sol–gel process are based on an organic–inorganic network [polymer chains (poly(propylene glycol), PPG) and (poly(dimethylsiloxane), PDMS) crosslinked by silica...
