Abstract
Provided are a hydrophilic aluminum surface body having a hybrid nanostructure and a manufacturing method thereof. The hydrophilic aluminum surface body includes an aluminum substrate; and a nanopattern including a hybrid nanostructure formed on a surface of the aluminum substrate, wherein the hybrid nanostructure includes nanoparticles and a plurality of nanoflakes around the nanoparticles. According to the manufacturing method of the hydrophilic aluminum surface body, hydrophobic aluminum may be artificially prepared as hydrophilic or superhydrophilic aluminum due to a small contact angle, and large-area and mass production is possible and the method is eco-friendly.
