From: Evaluation of corrosion performance of superhydrophobic PTFE and nanosilica coatings
A water droplet on sample with PTFE and nanosilica superhydrophobic coatings: (a) nano silica46, (b) micro Al2O3—with nano SiO2, (c) micro glass beads—without nano SiO2, (d) micro glass beads—with nano SiO246.
