2019-5-25 · Silica mesoporous thin films have been synthesized with a self-assembling process using cetyltrimethylammonium bromide as an organic template and tetraethyl orthosilicate as the silica source. Mesoporous films with Pm3n cubic phase have been obtained and the films have been thermally treated in air with a progressive heating schedule from as-deposited up to 1000 °C.

Mesostructured silica films have been used as a host matrix to incorporate spiropyran molecules via one-pot synthesis. The mesostructure of the films has not been changed by the introduction of the molecules and the films appeared optically transparent immediately after the deposition.

The directional distribution of the mesochannels in the films, which is estimated by in-plane X-ray diffraction, was very narrow and was comparable with that in the oriented mesostructured silica films prepared using hexadecyltrimethylammonium chloride as a templating agent.

2008-12-1 · Mesostructured silica films were formed through a nano-phase transition under the infiltration of TEOS into the surfactant films. It was found that the calcined film had a 3D pore structure from the field emission scanning electron microscope (FE-SEM) observations in a different orientation.

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.

The preparation method was based on solvent‐evaporation induced self‐assembly (EISA), with MTES (CH 3 –Si(OCH 2 CH 3 ) 3 ) as the silica precursor and a polystyrene‐ block ‐poly(ethylene oxide) (PS‐ b ‐PEO) diblock copolymer as the structure‐directing agent. 2013-06-11 · This can be regarded as a kind of heteroepitaxy because the lattice constant at the surface is different from that of the bulk of the film. On the basis of this new concept, highly aligned mesostructured silica films with structural periodicities as large as 10 nm are successfully formed, which has never been achieved when the block copolymers are used alone as the structure-directing agent. Thin films ofbicontinuous cubic mesostructured silica were formed using the nonionic poly(oxyethylene)-alkyl ether surfactant Brij-56 as a structure-directing agent. The synthesis conditions were chosen such that the estimated volume fraction of surfactant in the silica/surfactant films corresponded approximately to the composition at which the bicontinuous cubic phase occurs in the water/surfactant phase diagram.
