opfocus_v19_s2_p1_750Long gone are the days of teflon, when you could slap a chemical coating on something to make it repel water and other materials. Non-Stick is no longer the way to go with repelling products. Nowadays, there are some products that have to repel water and other buildup. So scientists looked at natural repellants like duck feathers, insect wings, and super repellents like the leaves of the lotus plant. When a product is omniphobic it will resist oil and other liquids from saturating the object.

Upon completion of this research shows that they repel liquids as a matter of design and not by use of any special coatings. Scientists tested this on silica to see if they too could etch or engrave the same sort of design and get the same reaction from liquids upon contact. The results are in and have advanced our understanding of Super-repellants. Now this process can be completed on more than one type of material with the same result, because it is by design and no special coating is needed. For example medical implants tend to get “gunk” on them over time and then don’t work as well as they had been designed to.

Microscopic Liquid-repellant or hydrophobic are far superior to the older method of plastic coating something to make it repel. In the past if the item got too hot the coating would fail. Now because the repellant is a part of the design itself there is nothing to “melt” off or fail. Use of microscopic bumps can ensure that a product is super-repellent by mechanics and not by use of a chemical.
