Surprising Water Slipping Performance on Highly Hydrophilic PEG‐Derived Monolayer‐Covered Surfaces: Preparation, Mechanism, and Application

Advanced Functional Materials, EarlyView.
Highly hydrophilic surfaces (water contact angle, ≈17.7°) exhibiting surprising water slipping performance (sliding angle, ≈7.3°) are successfully prepared via simple chemisorption of polyethylene glycol (PEG) organosilane and subsequent alkali‐treatment.

Influence of Surface Roughness on Superhydrophobicity [PDF]

Physical Review Letters, 2006
Superhydrophobic surfaces, with liquid contact angle theta greater than 150 degree, have important practical applications ranging from self-cleaning window glasses, paints, and fabrics to low-friction surfaces. Many biological surfaces, such as the lotus leaf, have hierarchically structured surface roughness which is optimized for superhydrophobicity ...

Nanocarpet Effect Induced Superhydrophobicity

, 2016
By coating a fluorocarbon monolayer on a bundled Si nanorod array substrate, a superhydrophobic surface with contact angle ∼167° and sliding angle ∼2° is created due to the nanocarpet effect.

Droplet Electricity Generators With Maximized Energy Collection Zone Enabled by Aloe‐Inspired Midrib and Cuticle

Advanced Materials, EarlyView.
An Aloe‐pinspired droplet electricity generator (A‐DEG) overcomes the limited energy collection zone of conventional DEGs by guiding impact droplets through a channeling midrib and artificial cuticle. The channeling midrib induces uni‐directional droplet spreading, while the artificial cuticle on the midrib further reinforces this behavior through its ...

Plastron Respiration Using Commercial Fabrics

, 2014
A variety of insect and arachnid species are able to remain submerged in water indefinitely using plastron respiration. A plastron is a surface-retained film of air produced by surface morphology that acts as an oxygen-carbon dioxide exchange surface ...

The effect of sintering regime on superhydrophobicity of silicon nitride modified ceramic surfaces

Journal of Asian Ceramic Societies, 2021
The most common method of obtaining a superhydrophobic surface is to create a specific surface morphology and then coat it with a hydrophobic polymer. Numerous such morphological surfaces have been developed but are often fragile.
