Abstract
Organically modified silicates (ORMOSILs) are attractive materials due
to their vast applicability and easy synthesis. The doping of these
materials with sodium dodecyl sulfate (SDS) is interesting in the search
for good protonic conductors. The inclusion of different concentrations
of SDS in ORMOSIL membranes is investigated in the present work using
Raman and infrared spectroscopy, confocal Raman microscopy and confocal
imaging microscopy. The spectroscopic measurements allow us to assign
the vibrational modes to the chemical groups of the structures of SDS
and ORMOSIL. Furthermore, these measurements show that these materials
are composites, as no interactions are observed between the SDS and the
ORMOSIL matrix. The confocal Raman and confocal imaging techniques are
useful to study qualitatively the SDS insertion on the surface of
ORMOSIL. It was observed that the SDS sizes are very nonuniform.
