Synthesize the Structural and Optical Properties of Hybrid PMMA Nanocomposites Doped with Metal Oxides for High-performance Coating Applications for Yachts and Boats

Abstract

Background: The present study conducted a deep analysis of the structural and optical properties of hybrid polymer-based (PMMA) nanocomposites that were reinforced with a synergistic mixture of metal oxides (SiO₂, TiO₂, ZnO). The aim of this study was to develop advanced functional coatings capable of addressing environmental challenges. Moreover,  focusing on the improvement of the physical properties of the base material for precision industrial applications.

 Materials and Methods: The methodology included preparing thin films nanocomposite films  by the use of a casting solution with varying oxide weight percentages. The work relied on advanced optical measurements, particularly diffuse reflectance and absorption spectroscopy, in order to obtain an accurate determination for the refractive index and optical bandgap of the prepared films.

 Results: The results revealed that the incorporation of the hybrid oxides resulted in a substantial enhancement of light stability and UV shielding efficiency in comparison to the pure polymer. The measurements also approved the maintenance of a suitable level of optical transparency, demonstrating a homogeneous distribution of nanoparticles within the polymer matrix and a considerable improvement in specific optical properties.

 Conclusion: The work showed that the prepared nanocomposite revealed a superior protection for yacht and boat surfaces against photocorrosion and harsh marine environmental conditions. Such results denote a significant step towards the production of high-performance functional coatings that combine protective efficiency with optical transparency. This could make them an ideal choice for modern marine applications.
