“…Indeed, the fogharvesting abilities of these surfaces allow the vapor to form tiny water droplets; the assembled fog will bounce or slip without wetting the surface. 160 When a passive antifogging function is introduced to food-contact surfaces, condensed water droplets are spread into a very thin, continuous, nonlight-scattering layer of water and may not find sufficient time to convert to large-sized water clusters. Antifogging effects of various nonwettable surfaces in harvesting are due to a range of mechanisms.…”

The adhesion of sticky liquid foods to a contacting surface can cause many technical challenges. The food manufacturing sector is confronted with many critical issues that can be overcome with long-lasting and highly nonwettable coatings. Nanoengineered biomimetic surfaces with distinct wettability and tunable interfaces have elicited increasing interest for their potential use in addressing a broad variety of scientific and technological applications, such as antifogging, anti-icing, antifouling, antiadhesion, and anticorrosion. Although a large number of nature-inspired surfaces have emerged, food-safe nonwetted surfaces are still in their infancy, and numerous structural design aspects remain unexplored. This Review summarizes the latest scientific research regarding the key principles, fabrication methods, and applications of three important categories of nonwettable surfaces: superhydrophobic, liquid-infused slippery, and re-entrant structured surfaces. The Review is particularly focused on new insights into the antiwetting mechanisms of these nanopatterned structures and discovering efficient platform methodologies to guide their rational design when in contact with food materials. A detailed description of the current opportunities, challenges, and future scaleup possibilities of these nanoengineered surfaces in the food industry is also provided.

“…The demand for superhydrophobic non-metallic surfaces is increasing in various fields, including construction, automotive, aerospace and medical industries. For instance, superhydrophobic modification of transparent materials like inorganic glass or organic polymers can prevent fogging, improve self-cleaning ability and enhance safety of use [38]. In applications involving composite materials, such as wind turbine blades and aircraft wings, using superhydrophobicity to prevent icing has become a recent research focus [39,40].…”

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.

Antifogging coatings are urgently needed in daily life. However, current research efforts seldom focus on enhancing the mechanical wear resistance of coatings or investigating their antifogging properties under wet and dry conditions. Herein, a robust dual-cross-linked polymeric antifogging coating was developed through the UV curing of poly[(methacryloxyethyl)dimethylheptylammonium bromide−acrylic acid] (pMDHAB− AA) and poly(ethylene glycol) diacrylate (PEGDA). Taking advantage of the dual-crosslinked structure and the delicate balance of hydrophilic−hydrophobic components in pMDHAB−AA, the coating presented durable antifogging performances, including longtime antifogging in hot vapor and numerous antifogging in an alternation of wetting and drying and robust mechanical wear resistance. In addition, based on the hygroscopic nature of the quaternary ammonium groups, the coating was endowed with oleophobicity underwater, an ultralow friction coefficient, and antibacterial and resistance-to-bacterialadhesion performances. More importantly, the antifogging coating plays a crucial role in enhancing substrate transparency by reducing the diffuse reflection. This prepared material addresses current concerns related to antifogging coatings and holds significant potential for applications in various fields, including optical glass, medical devices, agricultural films, etc.
