Superhydrophobic Aerogel of Polytetrafluoroethylene/Graphene Oxide Composite
Polytetrafluoroethylene-based aerogel has been synthesized for the first time. Graphene oxide has been used as a binder. After reduction with hydrazine and annealing at 370°C, the aerogel surface has been found to become superhydrophobic (the contact angle of water is 162°). Superhydrophobic aerogel with a specific gravity of 30 mg/cm3 has been characterized by IR spectroscopy and X-ray photoelectron spectroscopy.
