As we know sol-gel is one of the most important techniques for thin film preparation. In this paper, high transmission silica thin films have been prepared by dip-coating process from a new silicon-alkoxide solution. The prepared sol was stable for 45 days which is very important to characterize the coating process. The optical properties as a function of aging time, withdrawal rate, and he...

Dip coating consists of withdrawing a substrate from bath to coat it with thin liquid layer. This process is well understood for homogeneous fluids, but heterogeneities, such as particles dispersed in liquid, lead more complex situations. Indeed, introduce new length scale, their size, addition the thickness film. Recent studies have shown that, at first order, film monodisperse can be captured...

Abstract 316L stainless steel is one of the metal biomaterials used in implant applications because it has excellent mechanical strength. To improve biocompatibility and activity metals, a coating on surfaces required. coated with hydroxyapatite using dip technique. Firstly, suspension was prepared by mixing 10 grams hydroxyapatite, 1 gram sago starch, distilled water certain weight which then ...

In this work it is proposed a novel antibacterial surface composed of an organicinorganic hybrid matrix of tetraethoxysilane (TEOS) and a weak polyelectrolyte like Poly(acrylic acid sodium salt) (PAA) which are deposited on glass slides by sol-gel method using the dip-coating technique [1]. This work is focused in the in situ synthesis of Ag nanoparticles (NPs) which are responsible of the anti...

Photosensitive films incorporating molecular photoacid generators compartmentalized within a silica-surfactant mesophase were prepared by an evaporationinduced self-assembly process. UV-exposure promoted localized acid-catalyzed siloxane condensation, enabling selective etching of unexposed regions, thereby serving as a cresistIess’ technique to prepare patterned mesoporous silica. We also demo...
