JMS_V2_N4_RP2 Katlakanti Mohan Reddy Isaac Ramalla Kamal Bansal Journal on Material Science 2347–615X 2 4 9 12 Silica Coatings, AFM, FT-IR, Silica Nanoparticles To study the preparation and characterization of the sol-gel SiO2 nanoparticles using AFM (Atomic Force Microscope) and FT-IR (Fourier Transform Infrared Spectroscopy) are the best techniques to illustrate the purity, the presence of Si-O-Si bonds which are free from the organic matter, morphology and surface roughness of the silica coatings on glass and ceramic materials. The study carries the simple one-step preparation method and is well characterized using these two techniques, confirms the fine nanopowders which can be applied for the superhydrophobic surfaces to resist the contact of the water droplets on the coatings as well as exhibit the excellent hardness on different surfaces such as glass and ceramics.
