Superamphiphobic Web of PTFEMA Fibers via Simple Electrospinning Without Functionalization

Abstract

Abstract 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°. 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. magnified image
