CHARACTERIZATION OF pH SENSOR FILMS PREPARED BY THE SOL-GEL METHOD

The aim of this work is to determine the working range of the pH indicator after immobilization, to characterize the functional groups using Fourier-transform infrared spectroscopy (FTIR), and to determine whether the hydrophilicity of the surface changes when the coating is applied. In addition, the effect of post-curing and swelling of polyacrylate test plates in various solvents on coating adhesion was investigated. The degree of cure (DOC) of the plates was determined using DSC method. The test plates were manufactured using stereolithography (SLA) 3D-printing technology (Clear material) and sol-gel method was used to prepare the pH sensor films. The mixture for sensor film coating was prepared using silane precursors tetraethoxysilane (TEOS) and phenyltrimethoxysilane (FTMS), ethanol/water as solvent and hydrochloric acid (HCl) as catalyst for the sol-gel process with the addition of pH indicators. The indicators used in this work were methyl red and litmus. The functionality of the sensor film was investigated by placing the test plates covered with pH sensor films in ten solutions with different pH values. After the test, it can be seen that the pH sensor films change color depending on the pH of the solution (Fig. 1).
