In this study, titanium dioxide (TiO2) interlayer coatings were investigated to enhance the adhesion and durability of carbon dioxide(CO2) adsorbents. TiO2 films were deposited on glass substrates via spin coating at various speeds (100–1000 rpm) to regulate the surface properties. The surface morphology, roughness, wettability, and tribological characteristics were evaluated under both dry and aqueous conditions. The 100 rpm coating exhibited optimal performance with the highest surface roughness (0.38 μm) and superhydrophilicity (water contact angle: 18.25°), facilitating uniform adsorbent distribution. Tribological tests revealed that properly modified TiO2 coatings reduced the friction coefficient from 0.66 (bare glass) to 0.61 (100 rpm) under dry conditions. In aqueous environments simulating actual CO2 capture systems, the 100 rpm coating maintained superior performance with the lowest friction coefficient (0.49). However, the coatings prepared at higher speeds (700-1000 rpm) exhibit severe delamination under both conditions. The coating deposited at 300 rpm demonstrated the best wear resistance (5.72 × 10⁻⁷ mm³/N·mm) under dry conditions. The results indicate that spin coating at 100–300 rpm produces TiO2 interlayers with an optimal combination of superhydrophilicity for adsorbent coating and mechanical durability for long-term stability, thereby providing guidelines for the development of efficient CO2 capture systems.
