Investigation of the synergistic effect of titania micro and nanoparticles on the hydrophobic properties of polyurethane composite coating
One of the ways to improve the performance of ceramic insulators in polluted climates is to use polymer coatings reinforced with ceramic particles. The purpose of this study is to compare the effect of adding Titania nanoparticles and Titania micro-nanoparticles on hydrophobic properties of PU. In this method, stearic acid, which is a cheap and environmentally friendly material, was used for su...
متن کاملOhmic Contact of Cu/Mo and Cu/Ti Thin Layers on Multi-Crystalline Silicon Substrates
Cu-Mo and Cu-Ti contact structures were fabricated on multi-crystalline silicon substrates to provide a low resistance ohmic contact. Deposition steps are done in an excellent vacuum chamber by means of electron beam evaporation and samples are then annealed for the realization of an efficient alloy layer. The effects of process parameters such as film thickness, annealing duration and temp...
متن کاملCoordination-Driven Controlled Assembly of Polyphenol-Metal Green Coating on Wood Micro-Grooved Surfaces: A Novel Approach to Stable Superhydrophobicity
A versatile, fast, and nature-inspired polyphenol chemistry surface modification was applied to prepare superhydrophobic surfaces with micro-grooved structures in this study. Tannic acid and iron ion (TA–FeIII) complexes were employed as a molecular building block for anchoring biomimetic coating onto the wood substrate with catalytically reducing formative Ag ions as the rough surface to ensur...
متن کاملDrop Impact Study on Flexible Superhydrophobic Surface Containing Micro-Nano Hierarchical Structures
Superhydrophobic surfaces are abundant in nature. Several surfaces such as wings of butterfly, legs of water strider, feet of gecko and the lotus leaf show extreme water repellence behaviour. Self-cleaning, stain-free fabrics, spill-resistant protective wears, drag reduction in micro-fluidic devices etc. are few applications of superhydrophobic surfaces. In order to design robust superhydrophob...
متن کاملMicro-nano hybrid structures with manipulated wettability using a two-step silicon etching on a large area
Nanoscale surface manipulation technique to control the surface roughness and the wettability is a challenging field for performance enhancement in boiling heat transfer. In this study, micro-nano hybrid structures (MNHS) with hierarchical geometries that lead to maximizing of surface area, roughness, and wettability are developed for the boiling applications. MNHS structures consist of micropi...
