Attractive Repellent

November 2019

Greasy fingers and stainless steel surfaces – a combination that’s irritating countless people in and around the home. Now Germany’s Fraunhofer Institute thinks it’s found a solution to this age-old problem.

Together with colleagues at the FEW Chemicals company in the town of Wolfen, researchers have developed an anti-grease nanocoating system to combat unsightly smudges. Nanoparticles integrated in the coating make surfaces rougher and increase their surface area, meaning that grease never actually reaches the valleys of things like refrigerator doors.

The process is currently in the testing phase, with researchers developing means to determine just how effective the nanocoating is. There will be further optimization.

Developments should be completed by the end of 2020, at which point FEW Chemicals will commence industrial production.
