A microstructural study on surfactant templated silica films is performed by
coupling traditional X-Ray Diffraction (XRD) and Transmission Electronic
Microscopy (TEM) to Grazing Incidence Small Angle X-Ray Scattering (GISAXS).
By this method it is shown that spin-coating of silicate solutions with
cationic surfactant cetyltrimethylammonium bromide (CTAB) as a templating
agent provides 3D hexagonal structure (space group P63/mmc) that
is no longer compatible with the often described hexagonal arrangement of
tubular micelles but rather with an hexagonal arrangement of spherical
micelles. The extent of the hexagonal ordering and the texture can be
optimized in films by varying the composition of the solution.
