Wettability manipulation of magnetic transition metal nanorod arrays by X-ray irradiation

Abstract

Wettability manipulation of glancing angle deposited Fe/Co/Ni nanorod arrays was realized by X-ray irradiation in ultra-high vacuum chamber. Reversible transition was also purchased by alternating ethanol immersion and X-ray irradiation. Alkyl group adsorption–desorption mechanism and corresponding morphology dependence of wettability manipulation were revealed.

Keywords
