Assessment of Some Characteristics and Properties of Zirconium Dioxide Nanoparticles Modified with 3-(Trimethoxysilyl) Propyl Methacrylate Silane Coupling Agent

Abstract

This study presents the results of surface modification of zirconium dioxide (ZrO2) nanoparticles by 3-(trimethoxysilyl) propyl methacrylate silane coupling agent by assessing some characteristics and properties of modified ZrO2 nanoparticles by infrared spectroscopy, thermogravimetric analysis, size distribution, zeta potential, and field emission scanning electron microscopy methods. The modified and unmodified ZrO2 nanoparticles have been used as nanoadditives for organic coatings based on acrylic emulsion resin. The abrasion resistance of acrylic coating was evaluated according to ASTM E968-15. The obtained results show that ZrO2 nanoparticles were functionalized successfully with 3-(trimethoxysilyl) propyl methacrylate silane. The modified ZrO2 nanoparticles exhibit a positive effectiveness in the enhancement of the abrasion resistance of acrylic resin coating compared to unmodified ZrO2 nanoparticles.

“…However, the abrasion resistance value of acrylic coatings lled by TiO 2 nanoparticles modi ed by higher TMSPM content was lower than that of the acrylic/m-TiO 2 -3 coating. These obtained results were similar with the results determining the abrasion resistance of the acrylic coatings lled by ZrO 2 nanoparticles modi ed with TMPSM [31].…”

“…This new-formed layer covered the surface of nanoparticles and thus preventing silane coupling agent grafting continuously onto the TiO 2 nanoparticles. The silane coupling agent residues could be polymerized and thus forming the third phase in coating [20,31]. Hence, using the nanoparticles modi ed with high silane coupling agent content could reduce the regularity of the acrylic coatings.…”

“…Hence, the dispersion of the nanoparticles modi ed with silane coupling agent in polymer matrix was improved. However, the e ciency of the silane coupling agent grafted on the surface of the nanoparticles was reduced when using high silane coupling agent content [20,31]. The reason was that in the modi cation process, the silane coupling agent reacted with the hydroxyl groups on the nanoparticles' surface to produce a layer of silane coupling agent.…”

“…Moreover, the silane coupling agent could act as a bridge between TiO 2 nanoparticles and polymer matrix. Consequently, compatibility of m-TiO 2 nanoparticles with acrylic polymer matrix was improved [20,31]. It means that dispersion of m-TiO 2 nanoparticles in polymer matrix was enhanced.…”
