"To maximize the impact of our coating technology, we need to get it out of the lab," Wong said. To commercialize the technology, Wong, Wang and two other collaborators, Birgitt Boschitsch and Nan Sun, have created a startup company called spotLESS materials. The team found that the coating also could repel bacteria that spread diseases and odors. These pipes carry waste from the toilet, through a homeowner's sewer, to the municipal sewer.įrom a health perspective, the coating is also beneficial.
The toilet bowls of the future may not require water, but the drain pipes do. That makes it possible to flush with far less water than before, or, in theory, none at all. for Spotless Hair, focusing on manufacturing and selling high quality products, and developing materials and marketing strategies at the local level. When the team tested the coating on a toilet in the lab, dumping synthetic fecal matter onto it, the fake poop slid right down the sides without sticking. Better still, the coating takes less than five minutes to completely cure. The researchers believe the coating will withstand about 500 flushes before another lubricant layer must be sprayed onto the toilet bowl again. Next, the second spray adds a thin lubricating layer around those nanoscopic "hairs" that the first spray created.
Unsinkable Metal Could Lead to Unsinkable Ships."Our team has developed a robust bio-inspired, liquid, sludge- and bacteria-repellent coating that can essentially make a toilet self-cleaning," Tak-Sing Wong, associate professor of mechanical engineering and biomedical engineering, said in a press statement. It sounds gross, but it has the potential to help you cut down your water use and your water bill. Some of the scientists have gotten together on a new startup to sell the two-step coating spray, which they're already bringing to market under the name spotLESS.Įver see one of those toilets with the dual flush button on top? What about a brick in the water tank of a friend's toilet? Both are attempts to save water-the brick displaces some of the water, meaning smaller flushes, while those buttons let you control the size of your flush-but what if there was another way?Įngineers at Penn State University have come up with an alternate option: a new coating for toilet bowls that essentially keeps your poop from sticking.The researchers say this coating has the potential to create a self-cleaning toilet.Engineers at Penn State University have come up with a new coating that can cut down the amount of water needed to flush a toilet.
