Coating of Aluminum Alloy with Linseed Oil to Fabricate an Ultra-hydrophobic Self-cleaning Surface

Aluminum and aluminum alloys are useful materials in industry and society with potential for improved applications via creating novel properties such as superhydrophobicity and self-cleaning features. In this contribution, a superhydrophobic aluminum alloy surface was fabricated by an available and inexpensive mixture of fatty acids, linseed oil, through a handy low-cost approach. Overall, the modified aluminum substrate exhibited a water contact angle of 159.9° and a contact angle hysteresis of approximately 1°. The water contact angle decreased after a few minutes and the superhydrophobic properties of the surface was changed to the hydrophobicity such that the contact angle decreased to lower than 120°.
