Marine oil spills seriously endanger sea ecosystems and coastal environments, resulting in a loss of energy resources. Environmental economic demands emphasize the need for new methods effectively separating oil-water mixtures, while collecting content at same time. A surface-tension-driven, gravity-assisted, one-step, separation method is presented sustained filtration collection from floating spill. benchtop prototype device uses selective-wettability (superhydrophobic superoleophilic)...
Superhydrophobic–superoleophilic (SS) materials have the prospect to be used in oil‐spill cleanup as treated felts because of their complete oil‐absorbing and water‐repelling properties. The main issues affecting practical application SS are low volume‐based absorption capacity (resulting a high cost), requirement for mechanical handling (squeeze out oil) recycling, storage stability collected oil. In this study, barrel‐shaped oil skimmer mainly composed an Cu foam glass barrel is developed...
Robust superamphiphobic coatings fabricated by a facile chemical deposition and low surface energy modification were coated on both hard soft materials to repel water oils.
Oil/water separation has been addressed by various materials characterized with superwettability, but most of the methods involve corrosive or toxic chemicals which will cause environmental concerns. Proposed herein is an environmentally friendly method to realize oil/water separation. Nylon mesh exposed atmospheric pressure plasma for surface modification, micro-/nanostructures and oxygen-containing groups are created on nylon fibers. Consequently, functionalized possesses...
Superhydrophobic surfaces with hydrophilic patterns have wide applications in biomedical and chemical analysis domains. In this work, a rapid, simple, top-down micromilling method was proposed for fabricating such as micro dots, line, circle grooves on superhydrophobic surfaces. This could be extended to construct various linear diverse substrates account of its mechanical material-removal mechanism. Hydrophilic were milled the Al alloy surface. The dots demonstrate great adhesion toward...
Abstract Droplet controllable manipulation over a wide temperature range has promising applications in microelectronic heat dissipation, inkjet printing, and high microfluidic system. However, the fabrication of platform for droplet using methods commonly used industry remains tremendously challenge. The popular method controlling droplets is highly dependent on external energy input relatively poor controllability terms motion behaviors environment, such as distance, velocity, direction...

The micro/nanometer-scale comprise micrometer-scale, rectangular-shaped, and step-like obtained electrochemical etching nanometer-scale Ag grains resulting from immersion in [Ag(NH3)2]+ solution. Surface energy reduced perfluorooctanoic acid (PFOA) containing –CF3 –CF2– groups. PFOA-modified rough enable the formation a composite solid–liquid–air interface with peanut...
Spontaneous pumpless transportation (SPT) of liquids has generated tremendous demands in microfluidic systems and advanced devices. However, the nonpolar organic on open platforms underwater remains a challenge because most existing SPT are only designed for use air. Here, we report surface-tension-driven system to transport various using extreme wettability patterns. The patterns were fabricated with wedge-shaped superoleophilic track superoleophobic background by combining CuCl2 etching,...
