Abstract: (576 Views)
Among various forms of mesoporous silica materials, mesoporous coatings are one of the most favorable in various applications such as optics, electronics, different types of sensors, corrosion protection coatings, etc. To investigate the fabrication of process and its effect on coating properties, in this study, single-layer mesoporous silica coating fabricated by Evaporation Induced Self-Assembly method and Cetrimonium bromide was used as the structure-directing agent. After preparing the stable solution and aging it for 7 days, the deposition was performed by the spin coating method and in order to remove the template, the sample was calcined for 4 hours at 450 ° C. To evaluate the fabrication conditions, the stability of the sol and surfactant removal process were studied. The sample was exhaustively characterized by low-angle X-ray diffraction and electron microscopy. The results of the tests showed a continuous and very smooth coating with a thickness of 500 nm and had an ordered structure with a pore size of 3 nm.
