High-strength super-hydrophobic double-layered PBO nanofiber-polytetrafluoroethylene nanocomposite paper for high-performance wave-transparent applications

A sol–gel film transformation and spraying approach has been developed to fabricate double-layered PBO nanofiber (PNF) nanocomposite paper nanocomposite paper. The construction of stable double-layered structures and nanofiber networks with extensive hydrogen bonds and coordination bonds led to ultraflexibility and excellent folding endurance of the nanocomposite paper. In addition, the nanocomposite paper possessed high wave-transparent coefficient, super-hydrophobicity, and self-cleaning performances.
