Abstract

This study explored nanosilica synthesis using colloidal silica, silica sand, and TEOS, utilizing rotary evaporator drying, sol-gel, and titration methods. It examined the influence of these techniques on silica’s functionalization and mechanical properties. Methacryloxypropyl trimethoxysilane was employed for silanation, with silica characterized using various analytical methods. Particle sizes from SEM images were 19 nm and 14 nm for rotary and sol-gel samples, respectively, while titration samples showed an irregular structure. Zetasizer analysis revealed larger particle sizes. The purity of silica powders ranged from 90% to 99%, and titration samples demonstrated the highest silanability. When used in dental composites, rotary-evaporated silica displayed promising suitability based on its mechanical and physical properties.
