“…If the surface undergoes superhydrophobic modification, they are highly suitable as a filtration material for water-oil separation [188][189][190]. Polylactic acid (PLA) is a degradable and environmentally friendly material that can be directly loaded or grown with nano-structures on non-woven fabric made of PLA [191,192]. Coating PLA nanospheres mixed with dioxane on non-woven fabric [193] can also impart excellent hydrophobic and oleophilic properties, completing the water-oil separation process.…”

Multiscale nano/micro-structured surfaces with superhydrophobicity are abundantly observed in nature such as lotus leaves, rose petals and butterfly wings, where microstructures typically reinforce mechanical stability, while nanostructures predominantly govern wettability. To emulate such hierarchical structures in nature, various methods have been widely applied in the past few decades to the manufacture of multiscale structures which can be applied to functionalities ranging from anti-icing and water–oil separation to self-cleaning. In this review, we highlight recent advances in nano/micro-structured superhydrophobic surfaces, with particular focus on non-metallic materials as they are widely used in daily life due to their lightweight, abrasion resistance and ease of processing properties. This review is organized into three sections. First, fabrication methods of multiscale hierarchical structures are introduced with their strengths and weaknesses. Second, four main application areas of anti-icing, water–oil separation, anti-fog and self-cleaning are overviewed by assessing how and why multiscale structures need to be incorporated to carry out their performances. Finally, future directions and challenges for nano/micro-structured surfaces are presented.
