Effect of Ti and Au buffer layers on controlling the density and wettability of well-aligned ZnO nanorod arrays grown on different substrates

Abstract

ZnO nanorod arrays (NRAs) have potential applications as building blocks for nanoscale electronic, optoelectronic, and sensing applications.

Engineered Sustainable Omniphobic Coatings to Control Liquid Spreading on Food-Contact Materials

“…The formation of rough cavities on the surface traps most of the light without much transmission, leading to a decrease in the optical transmittance. 36 Many routes are proposed in the literature for preparing biomimetic superhydrophobic surfaces for different applications. However, not all these surfaces are suitable for food-packaging applications because the opacity induced by hierarchical micro/nano topography strongly conflicts with the desired transparency and is a major barrier for scaling up and commercialization.…”

“…The challenge arises from the inherent promotion of higher surface roughness, which is essential for nonwetting functions. The formation of rough cavities on the surface traps most of the light without much transmission, leading to a decrease in the optical transmittance . Many routes are proposed in the literature for preparing biomimetic superhydrophobic surfaces for different applications.…”
