The surface of aerosilogel and macroporous and microporous glasses was modified with aromatic sulfo groups (≡Si(CH2)2-C6H4-SO3H) by the chemical assembly method. Composite solid electrolytes containing Nafion were prepared from the silica matrices with a chemically modified surface. The proton conductivity of the materials was studied by impedance spectroscopy. Composite materials based on Nafion...
