Silica thin films with a two-dimensional (2D) hexagonal structure were produced from TEOS and the F127 triblock copolymer PEO106PPO70PEO106. The of was deduced transmission electron microscopy (TEM) performed on microtomed sections 2D X-ray scattering technique adapted for film characterization. Both methods are complementary allow detailed characterization structure. pore channels within coatings organized in domains, which spin curve inside film, but align surface plan at air/film...
A simple sol−gel route has been developed for the preparation of mesoporous and nanocrystalline anatase thin layers. An hydrosol was first synthesized at room temperature from acidic hydrolysis titanium isopropoxide. The optimization synthesis parameters, including concentration, HCl/Ti H2O/Ti ratios, temperature, aging time, enabled us to produce a clear sol with very low ratio (equal 1). As function further thermal treatment conditions, it then possible control size crystallites (from 5...
Atomic layer deposition (ALD) is a technology offering the possibility to prepare thin films of high quality materials on aspect ratio substrates with precise thickness control, uniformity and excellent conformality, unique capability. Therefore, this route particularly suited for structural modification pore tailoring synthetic membranes. ALD coatings have been prepared wide variety membrane substrates, from inorganic templated supports porous polymers. This minireview aims provide an...
This work describes the detailed structural investigation of mesophase-templated mesoporous silica films by 1D and 2D X-ray scattering techniques transmission electron microscopy. The are prepared sol−gel dip coating with hexagonal templating mesophases, yielding structures consisting cylindrical pores whose axes aligned parallel to surface. It is shown that drying thermal treatments induce an unidirectional shrinkage layers in direction normal film. true rectangular symmetry only evidenced...
Hexagonal mesoporous silica layers were prepared by the sol–gel route using silicon alkoxides as precursors and alkyltrimethylammonium bromides to form templating liquid crystal mesophase. The synthesis conditions required obtain well-ordered crack-free investigated. Thin exhibiting these properties deposited from diluted sols. X-Ray diffraction enabled characterisation of thermal evolution their ordered structure crystalline texture. Their porosity was experimentally measured nitrogen...
This study reveals the connection between silver-doping method, resulting nature and amount of silver dopant together with structural properties long-term antibacterial activity composite coatings.
A previous paper described the low-temperature synthesis of mesoporous nanocrystalline anatase thin layers obtained by mesophase templating (Chem. Mater. 2003, 15, 2463). This work deals with structural characterization these and extension method to films a different mesostructure. Thus, two triblock copolymers are used as structuring agents effect volume fraction surfactant in dried is also considered. The determination mesostructures mainly based on 2D X-ray diffraction experiments,...
