In this work, we have studied low energy argon ion-induced modification of surface wetting property of molybdenum dioxide nanorod mesh. The nanorods were deposited on a conductive silicon substrate using a spin coating process. The coated thin films were irradiated at two different fluences of 5 × 10¹⁶ and 1 × 10¹⁷ ions cm⁻², respectively. With increasing ion doses, the nanorods tend to bend slightly and a kinky structure is observed in a cross-geometry. While the surface of the as-deposited sample is hydrophilic, the irradiated surface alters into hydrophobic. We have analyzed the morphological and structural properties of the surface in detail to realize the initial and altered wetting properties. Furthermore, the dynamical variations in the contact angle on the molybdenum dioxide surfaces are further investigated to understand the interactions between the water droplet, the sample surface, and the atmosphere. We foresee that such altered surfaces can be helpful to fabricate corrosion-resistant devices.

在这项工作中，我们研究了低能氩离子诱导二氧化钼纳米棒网表面润湿性能的改性。使用旋涂工艺将纳米棒沉积在导电硅基板上。涂覆的薄膜在 5 × 10 ¹⁶和 1 × 10 ¹⁷离子 cm ^-2两种不同的能量密度下进行辐照， 分别。随着离子剂量的增加，纳米棒倾向于轻微弯曲，并在交叉几何中观察到扭曲的结构。虽然沉积后样品的表面是亲水的，但经过辐照的表面变成疏水的。我们详细分析了表面的形态和结构特性，以实现初始和改变的润湿特性。此外，进一步研究了二氧化钼表面接触角的动态变化，以了解水滴、样品表面和大气之间的相互作用。我们预见这种改变的表面有助于制造耐腐蚀设备。
