| Abstract Scope |
Polymer composite coatings are applied to glass to produce a variety of enhanced properties like increased strength, corrosion resistance, anti-icing, and self-cleaning. However, research on polymer coatings for increasing the strength of glass containers is mostly limited to epoxy-based coatings. Poly (methyl methacrylate) (PMMA) with embedded SiO2 nanoparticles coatings show promising properties when applied to glass. To improve the effectiveness these coatings, have on glass strength, nanoparticle ratios must be investigated. PMMA powder was dissolved in an organic solvent and different ratios of SiO2 nanoparticles were added to the solution. The solutions were spin coated onto glass substrates. Coating thicknesses were evaluated using ellipsometry and laser profilometry. Mechanical testing was performed using a ball on three ball (B3B) fixture. If successful, this research will enable the glass container industry to light-weight bottles and jars without compromising strength, leading to continuing sustainability efforts in the packaging industry. |
