The Effect of 3-(Glycidoloxy Propyl) Trimethoxy Silane Concentration on Surface Modification of SiO2 Nanoparticles

SiO2 is widely used in nanocomposites as reinforcement nanoparticle to enhance mechanical properties especially wear resistivity. Prior use, surface modification with proper and sufficient coupling agent should be performed on it. Coupling concentration plays a key role process. In this study, the influence of 3-(glycidoloxy propyl) trimethoxy silane (GPTMS) nanoparticles, experimentally investigated. The nano-silica were by 30, 50, 80 110 wt.% GPTMS order introduce optimal complete Fourier Transformation Infrared Spectroscopy (FTIR), Field Emission Scanning Electron Microscopy (FESEM), Thermo Gravimetric Analysis (TGA) X-Ray Diffraction (XRD) characterized pure modified samples; then, results compared each other achieve aim research. FTIR confirmed silanization proceed due absorption peak disappearing shifting hydroxyl group bonds amide bonds. This test showed that 30 has not been for full functionalization NPs. According FESEM images, it seems NPs better least aggregation lack deposition Also, TGA illustrates sample higher thermal stability because lower weight loss (11.2%) decomposition temperature range: 130–380 °C. Furthermore, about mentioned its highest crystallite size (increase 26.64% comparison sample). So, introduced nanoparticles.
