Unfortunately, films did not appear to retain their mesostructure after calcination. It was proposed that films formed as surfactants diffuse to the interface, where they complex with the polyelectrolyte. The mesostructured inorganic–organic hybrid pigments provide a mechanically and chemically rigid framework that protects the dyes and facilitate handling. We show that an organic latex binder can be used to prepare transparent photochromic films of varying thickness. For the first time X-ray patternable mesostructured silica films have been fabricated; this experiment opens the route to new technologies for functional applications.Block copolymer surfactant Pluronic F127, bis(4-tert-butylphenyl)iodonium p-toluenesulfonate (PG), and ethanol (EtOH) were purchased from Aldrich and used as-received.

Film Deposition Films were deposited by dip or spin coating on silicon wafers. The silicon wafers were cut into 10 u 20 mm pieces with a diamond pen. Mesostructured silica films are widely studied due to their different structures, properties and variety of possible applications. Sodium dodecyl sulfate (SDS)-templated sol-gel silica films possess highly ordered lamellar phase structure.

2003-12-15 · 1.. IntroductionThe preparation of mesostructured silica thin films attracted considerable attention due to the potential industrial applications as separation membranes, selective sensors, low dielectric coatings and templating layers for growth of conductive and optical devices .Evaporation induced self-assembly (EISA) method performed via dip- or spin-coating is widely used for the 2019-5-26 · Periodic Mesostructured Silica Films Made Simple Using UV Light | The Journal of Physical Chemistry C Recent research has shown that silica/surfactant self-assembly combined with photoacid-catalyzed sol–gel polymerization can direct the formation of disordered mesoporous silica films. An electrochemical resistive-type sensor device, with a mesoporous silica thin film as sensitive membrane, has been developed and characterised.

The primary goal of this research was to synthesize water- and oil-repellent coatings that offer sustained functionality and durability. Engineered low surface energy materials generally suffer from a lack of mechanical robustness, which makes them susceptible to damage by abrasive wear.

This paper shows that the refractive index variation is a 2011-4-26 · GMO/silica films were synthesized using a similar procedure as that previously described for phospholipid/silica films 13, 14, with the exception that a co-surfactant was added to the precursor sol in a 1:10 co-surfactant/GMO mass ratio in order to improve both the macroscopic and nanoscale quality of the resulting films (Fig. 1A).For co-surfactants, we investigated both synthetic amphiphiles 2007-1-22 · mesostructured silica films allowed the incorporation of the charge-transporting molecule (carbazole) and the second-order chromophore (DR1) in SDS-templated films. In these films, the DR1 molecules were oriented by a corona discharge.

Chmelka*,† †Department of Chemical Engineering and ‡Department of Chemistry and Biochemistry, University of California, Santa Barbara, 2018-3-1 Order in mesoporous silica films is, in fact, connected to the structural organization of pores, to transitions between different types of phases, the presence of well-defined building block units, and structure in the pore walls. Mesoporous films composed of amorphous silica with periodically arranged pores are promising materials as catalyst supports, sensors or filtration membranes. Solvent evaporation-induced self-assembly methods based on supramolecular organization of amphiphilic molecules in combination with sol-gel processing of condensable inorganic precursors result in porous thin films with a monomodal pore size distribution. By employing high speed spin coating for the film formation and high temperature (80 °C) drying and aging, we developed a synthesis procedure for mesostructured silica thin films that can reproducibly produce up to eight different pore morphologies, including a rhombohedral (R m), a centered rectangular (c2mm), two wormlike, two curved lamellar, and two lamellar structures.
