abstract = {Slot-die printing, a large-scale deposition technique, is
applied to fabricate mesoporous titania films. Printing is
interesting, for example, for scaling up solar cells where
titania films with an interconnected mesoporous network and
a large surface-to-volume ratio are desired as photoanodes.
A fundamental understanding of the structure evolution
during printing is of high significance in tailoring these
films. In this work, we provide important insights into the
self-assembly of the slot-die-printed
titania/polystyrene-block-poly(ethylene oxide) (PS-b-PEO)
micelles into ordered hybrid structures in real time via in
situ grazing-incidence small-angle X-ray scattering
(GISAXS). GISAXS allows for tracking both vertical and
lateral structure development of the film formation process.
In the hybrid film, a face-centered cubic (FCC) structure is
preferentially formed at the interfaces with air and with
the substrate, while a defect-rich mixed FCC and
body-centered cubic (BCC) structure forms in the bulk. After
calcination, the surface and inner morphologies of the
obtained nanostructured titania films are compared with the
spin-coated analogues. In the printed films, the initially
formed nanoscale structure of the hybrid film is preserved,
and the resulting mesoporous titania film shows a superior
order as compared with the spin-coated thin films which can
be beneficial for future applications.},
