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.
Highlights
IntroductionZirconium dioxide (ZrO2) or zirconia nanoparticles have been used in many technological fields such as catalysis, sensors, dielectric materials, polymeric nanocomposites, metallic nanocomposites, coating, semiconductor, or optical materials, thanks to their advantages including high strength, good natural color, high transparency and chemical stability, transformation toughness, thermal stability, chemical resistance, anticorrosion, and microbial resistance. ere are several available methods for producing zirconia nanoparticles, consisting of hydrolysis, sol/gel, hydrothermal, pyrolysis, microwave plasma, or thermal treatment [1,2,3,4]
Yan et al modified ZrO2 nanoparticles using N-(2-aminoethyl)-c-aminopropylmethyl dimethoxy silane coupling agent and investigated the effect of nanometer ZrO2 content and silane coupling agent on the friction and wear properties of bismaleimide (BMI) nanocomposites [14]. e presence of ZrO2 nanoparticles contributed to the decrease in the frictional coefficient and the wear rate of the nanocomposites. e modified ZrO2 nanoparticles were dispersed in a polymer matrix better than untreated ZrO2 nanoparticles, leading to the better tribological performance of nanocomposites containing modified ZrO2 nanoparticles
Sayılkan et al modified the surface of ZrO2 nanoparticles with 2-acetoacetoxyethyl methacrylate for optical purposes [3]. e modified ZrO2 nanoparticles have a size of 6.22 nm and 14.7 nm. e surface modification increases the stabilization of ZrO2 nanoparticles [15]
Summary
Zirconium dioxide (ZrO2) or zirconia nanoparticles have been used in many technological fields such as catalysis, sensors, dielectric materials, polymeric nanocomposites, metallic nanocomposites, coating, semiconductor, or optical materials, thanks to their advantages including high strength, good natural color, high transparency and chemical stability, transformation toughness, thermal stability, chemical resistance, anticorrosion, and microbial resistance. ere are several available methods for producing zirconia nanoparticles, consisting of hydrolysis, sol/gel, hydrothermal, pyrolysis, microwave plasma, or thermal treatment [1,2,3,4]. E mechanical and thermal properties of PUA coating were improved significantly with the presence of functionalized ZrO2 nanoparticles. E evaluation of the effect of modified ZrO2 nanoparticles on the abrasion resistance of emulsion acrylic resin can contribute to developing the paint system based on acrylic and nanoadditives in life sciences and technologies. It can be recognized that the surface modification of ZrO2 nanoparticles is necessary to improve their dispersibility in a polymer matrix. E purpose of this work is to evaluate some characteristics, properties including grafting efficiency, functional groups, thermal stability, size distribution, and water stability of ZrO2 nanoparticles modified with 3-(trimethoxysilyl) propyl methacrylate silane. The effect of silane content as well as modified ZrO2 nanoparticle content on abrasion resistance of emulsion acrylic coating has been tested and discussed
