<p>This study focuses on the application of nanoceramic coating on top of the TPU-coated fabric to achieve enhanced weather resistance and longer service life. For this purpose, nanoceramic coatings based on methyltrimethoxysilane-modified silica nanoparticles were synthesized via the sol–gel method, and ZnO nanoparticles dispersed into the modified silica sol at varying concentrations. The synthesized nanoceramic coating solution was successfully applied on top of the TPU-coated nylon fabric, and the coated samples were exposed for natural weathering. The microstructural examination of the synthesized nanoceramic coating was verified through X-ray diffraction and Fourier transform infrared spectroscopy techniques. Morphological characterization and elemental analysis were conducted using scanning electron microscopy, transmission electron microscopy, atomic force microscopy, and energy-dispersive X-ray spectroscopy. The helium gas transmittance rate (GTR), assessed with a gas permeability tester, exhibited a decrease from 2.16 to 1.1 L/m²/day after applying the nanoceramic coating. The efficacy of the synthesized nanoceramic coating was evaluated following 30&#xa0;days of natural weathering. The GTR values for the control and nanoceramic-coated samples were 2.16 and 1.1 L/m²/day before weathering and 1.85 and 1.19 L/m²/day after weathering, respectively. Similarly, the yellowness index for the control and coated samples was 3.498 and 0.2, respectively. Morphological analysis also indicated minimal degradation of surface properties when the nanoceramic coating was applied. Consequently, the application of the nanoceramic coating demonstrated effectiveness in enhancing weather resistance and mitigating UV degradation of the TPU-coated nylon fabric.</p>
