Abstract
This study focuses on the synthesis and characterization of nanoparticles, specifically titanium dioxide (TiO2) with a uniform size of approximately 5–8 nm in diameter. The nanoparticles exhibit high dispersibility and stability in hydrophilic environments. Notably, nitrogen-doped nanoparticles demonstrate intriguing self-cleaning properties, as evidenced by the degradation of methylene blue stain under UV light. Rutile nanoparticles stabilize color and color fastness in the presence of anatase-covered surfaces. Anti-mold tests reveal enhanced antimicrobial properties of the surfaces containing titania NPs when functionalized with polyethylene glycol (PEG). Ascorbic acid functionalized nanoparticles show promising behavior, encouraging the exploration of nanoparticle functionalization for property improvement. Leather samples coated with nanoparticles undergo abrasion, wear, and scratch resistance tests. The nanoparticles significantly enhance abrasion resistance, doubling the resistance. This suggests the potential for nanoparticle-based finishing to improve fastness to dry and wet rubbing, reducing defects in the coating.
