Abstract
Hierarchically mesoporous TiO2 films with a high degree of order and connectivity on the sub-100-nm scale are successfully fabricated by the dual-templating methods sequentially applied. In this approach, the self-assembly of block copolymers combined with sol-gel reaction is first used to generate highly ordered mesoporous films by optimizing their self-assembling behavior. At the next step, 50-nm PS nanoparticles are deposited on the mesoporous films generated in the previous step to produce the colloidal crystals, and their inverse structure with a high degree of order, otherwise, would not form the colloidal crystals but generate a colloidal glassy phase with poor order. In addition to the exceptionally high degree of order, mesoporous films exhibit a high porosity that spans from the top surface to the bottom surface throughout the entire film without clogging. Especially wide pores at the top layer enable functional materials of large size to access the inside the films with small pores, maximizing their performance. As a proof of concept, photocatalytic effects are examined for the mesoporous films with different structures. In terms of the template pattern, the line pattern and bowl structure are also shown to guide the self-assembly of colloidal particles when their characteristic size matches with the particle diameter, in addition to the hexagonal packing.

Abstract
A facile route to reassemble titania nanoparticles within the titania-block copolymer composite films has been developed. The titania nanoparticles templated by the amphiphilic block copolymer of poly(styrene)-block-poly (ethylene oxide) (PS-b-PEO) were frozen in the continuous PS matrix. Upon UV exposure, the PS matrix was partially degraded, allowing the titania nanoparticles to rearrange into chain-like networks exhibiting a closer packing. The local structures of the Titania chain-like networks were investigated by both AFM and SEM; the lateral structures and vertical structures of the films were studied by GISAXS and X-ray reflectivity respectively. Both the image analysis and X-ray scattering characterization prove the reassembly of the titania nanoparticles after UV exposure. The mechanism of the nanoparticle assembly is discussed.

Abstract
Sol-gel templating of titania thin films with the amphiphilic diblock copolymer poly(dimethyl siloxane)-block-methyl methacrylate poly(ethylene oxide) is combined with microfluidic technology to control the structure formation. Due to the laminar flow conditions in the microfluidic cell, a better control of the local composition of the reactive fluid is achieved. The resulting titania films exhibit mesopores and macropores, as determined with scanning electron microscopy, X-ray reflectivity, and grazing incidence small angle X-ray scattering. The titania morphology has three features that are beneficial for application in photovoltaics: 1) a large surface-to-volume ratio important for charge generation with disordered hexagonally arranged mesopores of 25 nm size and a film porosity of up to 0.79, 2) enhanced light scattering that enables the absorption of more light, and 3) a dense titania layer with a thickness of about 6 nm at the substrate (bottom electrode) to prevent short circuits. An optical characterization complements the structural investigation.

Abstract
Titania nanoparticles are prepared by sol–gel chemistry with a poly(ethylene oxide) methyl ether methacrylate-block-poly(dimethylsiloxane)-block-poly(ethylene oxide) methyl ether methacrylate triblock copolymer acting as the templating agent. The sol–gel components—hydrochloric acid, titanium tetraisopropoxide, and triblock copolymer—are varied to investigate their effect on the resulting titania morphology. An increased titania precursor or polymer content yields smaller primary titania structures. Microbeam grazing incidence small-angle X-ray scattering measurements, which are analyzed with a unified fit model, reveal information about the titania structure sizes. These small structures could not be observed via the used microscopy techniques. The interplay among the sol–gel components via our triblock copolymer results in different sized titania nanoparticles with higher packing densities. Smaller sized titania particles, (∼13–20 nm in diameter) in the range of exciton diffusion length, are formed by 2% by weight polymer and show good crystallinity with less surface defects and high oxygen vacancies.
