Flexible carbon nanotube-polymer composite films with high conductivity and superhydrophobicity made by solution process.
CNT/Nafion nanocomposite film made by solution process exhibits high conductivity and superhydrophobicity. The highest water contact angle reaches 165.3 +/- 1.9 degrees. The wettability of the film can be controlled by simply varying the filtering rate and the content ratio of Nafion to CNT. We also develop a novel optical method to directly observe the air-solid-liquid interface for the first time. The extraordinary mechanical strength provided by the polymer helps the film retain its conductivity and superhydrobicity after 1000 bending cycles.
