Abstract: We describe a simple and inexpensive technique to fabricate superhydrophobic coatings with furfural acetone resin/poly (tetrafluoroethylene) (FAR/PTFE) composites. An interesting hierarchical structure with dispersed cavities and protuberances in microscale was achieved. The water contact angle (CA) of the superhydrophobic surface is 157° and the sliding angle is about 5°. The coatings can be applied to large substrates by spray coating with ease and possess high cohesional strength with the substrates. Meanwhile, the superhydrophobic coatings show long-term stability in pure water and acidic solutions with higher concentration.
