Abstract:

Introduction. Architectural coatings are crucial in contemporary eco-friendly design, as they protect the appearance of buildings, extend their service life, and enhance aesthetic appeal. However, traditional formulations often contain volatile organic compounds (VOCs) and other harmful chemicals. The field of nanotechnology offers an innovative approach to improve coating efficiency while minimising environmental impact. This study focuses on the development and application of nano-enhanced coatings, particularly those which are self-cleaning, antimicrobial, and heat-reflective. Additionally, it assesses their potential effects on the maintenance and operation of the structure by increasing durability and reducing resource consumption.

Methods. Our research concentrated on synthesising and characterising nanocomposites derived from silicon dioxide, titanium dioxide, and silver nanoparticles, which were integrated into both water- and solvent-based polymer matrices. The samples were subjected to laboratory evaluations that simulated real-world conditions, including UV exposure, thermal cycling, and prevalent microbial challenges. Performance metrics such as surface hydrophobicity, microbial inhibition, and thermal reflection coefficients were quantified through agar diffusion analysis and infrared spectroscopy.

Results. Preliminary results indicate that nano-enhanced coatings offer significant operational advantages compared to traditional systems. Self-cleaning formulations exhibit enhanced water-repellent properties, which reduce dirt accumulation and decrease cleaning intervals. Antimicrobial coatings have effectively decreased bacterial proliferation and biofilm formation, as demonstrated by standardised testing parameters. Furthermore, heat-reflecting options show reduced heat absorption, minimising cooling requirements in controlled simulations.

Conclusions. Using nanotechnology, architectural coatings can achieve excellent multifunctional performance while reducing resource consumption and pollutant emissions. The widespread use of nano-enhanced coatings can significantly improve the environmental friendliness and cost-effectiveness of buildings and structures that do not require special care.
