“…Among different icephobic materials, nontoxic and low-cost fluorine-free materials with extremely low surface energy have better potential to be used as passive ice protection for food-contact surfaces. Liu et al − designed a study to compare the SLIPS’s anti-icing/deicing capability and that of superhydrophobic coatings. The authors noted that SLIPSes manifested an approximately 20-fold longer ice-nucleation time than superhydrophobic surfaces.…”

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 accumulation of ice and the cleaning work behind it has brought a lot of inconvenience for people. − In recent decades, various fluorine- and silicon-containing materials for anti-icing have been well-developed due to their excellent performance in reducing ice adhesion. − At present, investigations on anti-icing materials mainly focus on hydrophobic/superhydrophobic surfaces, slippery liquid-infused surfaces (SLIPS), and gels. − …”

Developing smart organogels with simultaneous low ice adhesion, high mechanical strength, and durability through a simple method has proven to be challenging yet valuable. In this work, organogels (NF-x) possessing variable liquid paraffin contents (0−50 wt %) with fluorinated polynorbornene networks were produced by ring-opening metathesis polymerization (ROMP) using norbornene-trifluoroethyl ester (NF) and dinorbornyl glycol ester (NEG) as monomer and cross-linking agent, respectively. The stability, mechanical behavior, anti-icing, and antifrosting properties were comprehensively investigated. Owing to the well-designed networks, the organogels exhibited excellent stability even under harsh conditions for long-term use. Unprecedentedly, they showed a reversible pressure-responsive effect, wherein the paraffin could migrate from the inside of the gels to form a self-lubricating layer covering the surface under external force and subsequently reabsorbed and recovered to the original state upon force removal, enhancing the on-demand secretion of lubricants to the surface. The sensitivity to the applied force (merely 4 kPa of NF-5) was positively correlated with the paraffin content in the organogels. Benefiting from the fluorinated polynorbornene networks and switchable self-lubricating property, the organogels showed excellent durability in mechanical, antiicing, and antifrosting properties. Additionally, the mechanical, anti-icing, and antifrosting properties could be adjusted by varying the paraffin content. Notably, the NF-5 ice-phobic coating with 50 wt % paraffin exhibited high mechanical strength (1.69 MPa) and low ice shear strength (17.65 kPa), even after 15 icing−deicing cycles, remaining below 28 kPa. This study offers an approach to conveniently develop smart anti-icing materials with high mechanical durability.
