Hybrid Hydrocarbon/Fluorocarbon Nanoparticle Coatings for Environmentally Friendly Omniphobic Surfaces

The release of fluorocarbons (FCs) into the environment is a growing problem for chemical industry. Fluorocarbons have been observed in increasing amounts across range different locations worldwide on account environmental polymers, consumer products, and other sources. These compounds show long biological half-lives linked to number negative toxicological effects. As such, their use should be restricted eliminated where possible. In this paper, we shown that amount fluorocarbon omniphobic coatings formed from carboxylate-functionalized nanoparticles can reduced by as much 70% without compromising properties such contact angle hysteresis (CAH) or sliding (SA). This reduction made possible using approaches involving adsorbing hybrid hydrocarbon carboxylate chains onto commercially available aluminum oxide nanoparticles. carboxylates are either coadsorbed same particles, referred chemically mixed (CM), attached which physically (PM). Both these types surface enhanced omniphobicity compared had functionalized fluorinated but did not contain any bearing chains. addition, synthetic feces surfaces were tested order investigate potential applications methodology. Similarly, it was could substantially significantly mixture surface.
