NEI Corporation announced today that it has introduced NANOMYTE® SuperCN Plus - a functionally graded coating that imparts superhydrophobic properties to the underlying substrate while providing greater abrasion resistance compared to existing superhydrophobic coatings. Surfaces treated with SuperCN Plus force liquids to bead up and roll off, shedding water instantly and leaving the surface completely dry. Somerset, NJ (PRWEB) March 26, 2014 NEI Corporation announced today that it...

Why Do Some Surfaces Repel Water, While Others Attract It?
2013-07-17 05:17:38

Lee Rannals for redOrbit.com - Your Universe Online Researchers at MIT are working on better understanding how surfaces attract or repel water. When water strikes a surface, sometimes it spreads evenly while other times it beads into tiny droplets. Studying this behavior can lead to improvements in many applications. If water strikes a material and maximizes its contact with it, then it is known as hydrophilic, but when water is naturally repelled on a material, it is called...

The wetting model is a classical problem in surface science and biomimetic science. Professor LIU Jianlin and his collaborators from China University of Petroleum, Wuhan University and Fourth Military Medical University approached this old and classical problem from a new direction. They stressed that it is the triple contact line and not the contact area of the droplet/solid interface that determines the macroscopic contact angle. The proposed continuum model, termed the mechanism-based...

The water boatman's unique propulsion system was studied by researchers from China Superhydrophobicity is one of most important interfacial properties between solids and liquids. SHI Yanlong and his group from the College of Chemistry and Chemical Engineering, Key laboratory of Hexi Corridor Resources Utilization of Gansu Universities, Hexi University investigated the superhydrophobicity of the water boatman's hind wings. The study showed that superhydrophobicity plays a crucial role in...

By Xu, Jing Liu, Xingbo; Bright, Mark A; Hemrick, James G; Sikka, Vinod; Barbero, Ever The reactive wetting behaviors of MSA2020, an Fe-based superalloy, and 316L stainless steel in contact with a molten Zn-Al alloy were investigated by the sessile drop method. This investigation led to the following findings. (1) 316L not only suffered considerable wetting, but also reacted with the molten Zn- Al alloy at a higher rate than MSA2020. (2) The contact angle of MSA2020 wet by the molten Zn-Al...

By Hwang, Chin-yin Hse, Chung-yun; Shupe, Todd F Abstract This study examined the effects of a compatibilizer on the wettability of birch plywood and polyolefins. The compatabilizer was a low molecular weight emulsion type maleated polypropylene (MAPP), Epolene E-43. The polyolefins investigated included low- density polyethylene (LDPE), linear low-density polyethylene (LLDPE), and polypropylene (PP). For E-43 treated wood surfaces, contact angles among four wetting liquids were in the order...
