Strategy toward fluorinated polyhedral oligomeric silsesquioxane wrapping nanoparticles for superomniphobic surfaces.

For engineering implementation of an ultralow-surface-energy hierarchically micro/nanostructured topography for superomniphobic surfaces, a strategy involving the design of a partially open-cage fluorinated polyhedral oligomeric silsesquioxane bearing an -OH pair (poc-F13POSS-2OH) and the subsequent wrapping of nanoparticles with poc-F13POSS-2OH as a result of weak-acid-triggered -OH protonation is developed. The poc-F13POSS-wrapped nanoparticle-based surfaces showed broad-spectrum superomniphobicity. This work has advanced the engineering of state-of-the-art superomniphobic solid surfaces/interfaces.
