abstract = {Nanostructured porous titania films are used in many energy
related applications. In this work, the temporal evolution
of the mesoscopic deformation of mesoporous titania films
synthesized via block copolymer assisted sol-gel chemistry
is investigated with in situ grazing incidence small-angle
neutron scattering (GISANS) during exposure to D2O vapor.
Two types of mesoporous titania films are compared, which
have a different degree of structural stability, depending
on the applied annealing temperature (400 °C versus 600
°C) in nitrogen atmosphere. Water ingression causes a
gradual structure deformation in terms of decreasing
center-to-center distances and broadening of the size
distribution of the titania nanostructures. Based on the
evolution of the mesopore size obtained from in situ GISANS
measurements, the results show that structures synthesized
at lower temperature undergo a stronger deformation due to
the lower elastic modulus originating from larger pores,
despite having a higher degree of order.},
