In this study anodization and annealing condition are optimized to fabricate nanotubular surface which is able to maintain its hydrophilicity over time - anti-aging surface. Our results indicate that anodization voltage and annealing temperature affect surface ability to maintain its hydrophilicity. Water contact angle measurements show hydrophilicty is sharply decreased after annealing regardless of annealing and anodization conditions. Non-anodized and 20 V anodized samples lose their hydrophilicity after 11 days of aging in air, while 60 V anodized samples are able to maintain their hydrophilicity after this period.
