Pancake bouncing on superhydrophobic surfaces [PDF]

Nature Physics, 2014
Engineering surfaces that promote rapid drop detachment is of importance to a wide range of applications including anti-icing, dropwise condensation6, and self-cleaning. Here we show how superhydrophobic surfaces patterned with lattices of submillimetre-scale posts decorated with nano-textures can generate a counter-intuitive bouncing regime: drops ...

Understanding the Role of Superhydrophobicity and Superhydrophilicity in Salt‐Spray Corrosion of Nanosecond Pulsed Laser‐Textured AA2024 Alloy

Advanced Functional Materials, EarlyView.
Nanosecond pulse laser texturing yields superhydrophobic and superhydrophilic AA2024 surfaces. Salt‐spray tests show that periodic superhydrophobic patterns suppress pitting, whereas superhydrophilic textures enhance it, linking laser‐induced morphology, wettability, and oxide chemistry to corrosion resistance.

Polymer Infiltration Into SURMOF Channels Enables Hydrophobic and Solid‐Like Slippery Functional Thin Films

Advanced Functional Materials, EarlyView.
We report a polymer‐chain insertion strategy to fabricate pore‐threaded MOF thin films with precisely tuned surface chemistry and wettability. Grafting n‐alkane chains into the pillared layer Cu2(bdc)2(dabco) MOF thin film's vertical nanochannels enhances water stability, and induces hydrophobicity and lubricant‐free, solid‐like slippery behavior ...

Fabrication of Fluorine-Free Superhydrophobic Surface on Aluminum Substrate for Corrosion Protection and Drag Reduction

Journal of Marine Science and Engineering, 2023
A fluorine-free cerium palmitate superhydrophobic surface on an aluminum plate was fabricated via a two-step electrodeposition method. The mechanical durability, anti-corrosion performance, water repellency and drag reduction properties were tested.

Sprayable Polymer Blends With Short‐Chain Surface Segregation for Preventing Postoperative Abdominal Adhesions

Advanced Healthcare Materials, EarlyView.
Adhesions’ high occurrence rates and high morbidity render them a critical challenge to be addressed. Current prevention methods, such as physical barriers, have many limitations, resulting in inconsistent safety and efficacy. This study demonstrates the potential for sprayable polymeric materials as an adhesion barrier.

Application of hydrophobic fluorinated silicon oxide nanoparticle coating on electrodynamic screen (EDS) films for enhancing self-cleaning function of solar collectors [PDF]

, 2020
Optical surfaces, which are exposed to outdoor environmental conditions, are susceptible to dust deposition. Sunlight incident on the surface of photovoltaic (PV) modules is attenuated by the dust layer accumulation on the front surface of the modules ...
