Drop evaporation on superhydrophobic PTFE surfaces driven by contact line dynamics.

•Highly hydrophobic surfaces were produced using Teflon substrates.•The evaporation kinetics of water droplets were studied at different temperatures.•The evaporation process is driven by the contact line dynamics (pinned/moving).•The energy barriers associated with the stick–slip motion of droplets are ∼nJm−1.•The evaporation rate constants are enhanced in the pinned contact line regime.
