This paper reports on a web of superamphiphobic fluoro-compound fibers that forms as a result of a typical electrospinning method without any additional treatment. An electrospun web of poly(2,2,2-trifluoroethyl methacrylate) fibers exhibits superamphiphobicity when the water and hexadecane contact angles both exceed 150 degrees. The morphology of a web is modulated by changing the polymer solution concentration from 24 to 30 wt.-% with other fixed processing conditions. The fiber diameter length depends mainly on the polymer concentration. A web formed from a 26 wt.-% solution has the smallest and most uniform fiber diameter; it also has the highest robustness parameter on wetting, thus the highest water and hexadecane contact angles. This result offers the possibility of simple industrial production of an amphiphobic surface.
