The work presented is devoted to new approaches increasing the superhydrophobic properties of coatings based on zinc oxide (ZnO) and titanium dioxide (TiO2). There an innovation in use inorganic with a non-polar structure, high melting point, good adhesion ZnO, contrast traditionally used polymer low performance characteristics. maximum superhydrophobicity ZnO surface (contact angle 173°) achie...

The most common method of obtaining a superhydrophobic surface is to create specific morphology and then coat it with hydrophobic polymer. Numerous such morphological surfaces have been developed but are often fragile. Ceramic-based coatings show longer life high wear resistance. In this study, micro-nano was β-Si3N4 powder the influence sintering regime on contact angle ceramic investigated. a...

Abstract Superhydrophobicity is usually achieved by a combination of chemical hydrophobicity and surface topography due to an inability attain complete non-wetting on the smooth existing materials. Here, we experimentally report high condensation-induced droplets with contact angles approaching 180° suspended monolayer graphene. Such highly are found graphene open water vapour saturated environ...

We report the fabrication of a sticky superhydrophobic paper surface with extremely high contact angle hysteresis: advancing contact angle ∼150◦ (superhydrophobic) and receding contact angle ∼10◦ (superhydrophilic). In addition, we report the controlled tunability of the contact angle hysteresis from 149.8 ± 5.8◦ to 3.5 ± 1.1◦, while maintaining superhydrophobicity, as defined through an advanc...

The manipulation of droplets is used in a wide range of applications, from lab-on-a-chip devices to bioinspired functional surfaces. Although a variety of droplet manipulation techniques have been proposed, active, fast and reversible manipulation of pure discrete droplets remains elusive due to the technical limitations of previous techniques. Here, we describe a novel technique that enables a...

In situ Pd-catalyzed cyclopentene polymerization in the presence of multi-walled carbon nanotubes (MWCNTs) is demonstrated to effectively render, on a large scale, polycyclopentene-crystal-decorated MWCNTs. Controlling the catalyst loading and/or time in the polymerization offers a convenient tuning of the polymer content and the morphology of the decorated MWCNTs. Appealingly, films made of th...

The development of super-hydrophobic surfaces has been inspired by natural systems and uses a number of novel (nano) technologies. Superhydrophobicity has stimulated much scientific and industrial interest because of applications in water repellency, selfcleaning, friction reduction, antifouling, etc. Despite its inherent hydrophilicity, cellulose has unparalleled advantages as a substrate for ...

The fabrication and advanced function of large area biomimetic superhydrophobic surfaces (SHS) and slippery lubricant-infused porous surfaces (SLIPS) are reported. The use of roll-to-roll nanoimprinting techniques enabled the continuous fabrication of SHS and SLIPS based on hierarchically wrinkled surfaces. Perfluoropolyether hybrid molds were used as flexible molds for roll-to-roll imprinting ...
