Résumé

Here we report for the first time the use of dithiolane as platform for reversible surface functionalization with switchable water and oil-wettability. That platform allows to prepare switchable superhydrophobic/hydrophilic surfaces and oleophobic/oleophilic surfaces. Based on a poly(3,4-ethylenedioxythiophene) surface bearing dithiolane groups, this strategy allows to obtain reversible functionalization of surfaces with various thiol compounds. Interestingly, the use of fluorinated thiols also highly changes the surface morphology and porosity leading to superhydrophobic properties and highly oleophobic properties with water and oil reversibility. Dithiolane surfaces are key platform in order to prepare switchable surfaces for a large range of applications.
