Abstract
In the research, the superhydrophobic protects based on TEOS as a replacement for silica are done with using the coprecipitation method. The characterized use Scanning Electron Microscope (SEM-EDS) and X-Ray Fluorescence (XRF), X-Ray Diffraction (XRD). The SiO2 diffraction peak was found at an angle of 2θ- = 31.680, according to the XRD characterization. The building block of silica is the primary structural unit SiO44-, which is made up of one Si4+ atom surrounded by four oxygen atoms that are joined ionically and covalently to form tetrahedral bonds. The element Si was discovered to be present based on XRF analysis. The morphology results, which display uniform shapes, are the result of the sample^s even grinding process. Based on XRF testing, it was found that the element Si was present. obtained from TEOS as a substitute for Silica.
