Abstract

Multiscale structures of biotic materials exhibiting natural integration provide a model for the development of functional surfaces with special wettability. Inspired by nature, for example, by the lotus leaf and butterfly wings that show excellent superhydrophobicity, scientists have recently fabricated a variety of biomimetic superhydrophobic membranes through various smart and easy routes. After a brief description of natural superhydrophobic surfaces and the structural and functional biomimetic surfaces, we present the design and fabrication methods of these bio-inspired superhydrophobic fibrous membranes. The main focus is the overview of the polymeric materials used to fabricate the superhydrophobic fibrous membranes at nano- or microscales and the chemical modifications that led to superhydrophobicity of as-prepared polymeric and inorganic fibrous membranes. Later, we describe the induced superhydrophobicity in common textile fibrous surfaces. In addition, we highlight some potential applications associated with these remarkable biomimetic surfaces.
