Optimization of hydrophobic nonresponsive sol-ketal acrylate gel film to hydrophilic thermo-responsive gel by graft-polymerization

Sol‐gel silicate thin‐film electronic properties

BaFe12O19 thin film grown by an aqueous sol-gel process

In this communication we present a new sol–gel route to obtain high quality BaFe12O19 thin films. X-ray analysis confirmed the crystal structure with a crystal size of 32 nm. Atomic force microscopy images determined the film thickness to be around 250 nm and a roughness factor of less than 40 nm where the grain size averaged around 150 nm. SQUID magnetometer data shows a magnetic behavior simi...

Introduction to Sol-Gel

Synthesis and Characterization of Hydrophobic Silica Aerogel by Two Step(Acid-Base) Sol-Gel Process

The silica aerogel was prepared by the acid–base sol–gel polymerization of tetraethylorthosilicate precursor followed by ambient pressure drying. The prepared silica aerogels were characterized by Fourier transform infrared )FT-IR(, Thermo-gravimetric and differential thermal analysis )TG/DTA(, X-ray diffractometer )XRD(, Energy dispersive X-ray microanalysis )EDX(, Brunauer–Emmitt–Teller (BET)...

Optical sol-gel coatings : ellipsometry of film formation

2014 A method was developed to image an area of a drying, steady-state film during dip-coating using ellipsometry, thereby obtaining the film’s thickness and refractive index as a function of position. Measurements on TiO2 and SiO2 alcohol-based sols indicate that the film approaches a volume fraction 03A6 ~ 0.2 in the wet state and suggests that the film resists densifying further for kinetic ...
