Slippery liquid-infused porous surfaces (SLIPSs), a class of functional bioinspired surface, have earned a position at the forefront of many areas such as anticorrosion, anti-icing, antifogging, antibacterial, anticontaminant, microflow control, and drag reduction. However, the fast self-replenishing ability of SLIPS remains extremely challenging due to limited lubricant storage capacity or microstructure impeding fluid flow. Herein, a superhydrophobic surface was prepared by spraying the sepiolite/zeolitic imidazolate framework-8 hybrid material with a layered three-dimensional (3D) fibrous porous network structure on the magnesium (Mg) alloy surface. Subsequently, SLIPS with fast self-replenishing properties was obtained by injecting silicone oil on the superhydrophobic surface. The unique internal structure of SLIPS not only served as a container for storing the lubricant but also provided a channel for the flow of lubricants. In addition, the SLIPS possessed favorable self-replenishment, anticontaminant, and anti-icing properties. Moreover, compared with the superhydrophobic surface, SLIPS exhibited better corrosion resistance, which was attributed to the stable continuous lubricating oil replacing the air trapped in the rough structure and effectively blocking the invasion of corrosive ions. Significantly, the as-prepared SLIPS still maintained excellent corrosion stability on the Mg alloy after soaking in 3.5 wt % NaCl solution for 30 days. The research provides an avenue for designing green environmental protection, sustainable anticorrosion, and rapidly self-replenishing SLIPSs with great application potential.

Intratumoral implants have aroused great interests for local chemotherapy of cancer, however, how to efficiently control drug release from implants is still a great challenge. Herein, we designed and prepared a new hollow bullet-shaped implant with porous surface by 3D printing, loaded chemotherapeutic agent cytoxan (CTX) with tetradecyl alcohol or lecithin as matrix and coated it with poly (lactic acid) to obtain a CTX implant, which has a highly tuned drug release property with a drug release time from 4 h to more than 1 month. The drug release from the implant can be easily controlled by changing pore sizes, kinds of matrices, and coating thickness.

Inspired by nepenthes pitcher plants, the slippery liquid-infused porous surfaces have received extensive attention. In its practical application, good oil storage and oil-locking ability are important guarantee for the surface to maintain the interface performance for a long time. In this paper, mesoporous silica (KCC-1) was obtained by cetyltrimethylammonium bromide (CTAB) as template agent, urea as a hydrolyzing agent, and TEOS as silicon source reagent, then modified with (3-Aminopropyl) trimethoxysilane. Then combined with the breath figures, amino-modified mesoporous silica, 3,3’-4,4’-biphenyltetracarboxylic dianhydride (S-BPDA), 2,2’-bis[4-( 4-aminophenoxyphenyl)]propane (BAPP) were used as raw materials to prepare polyimide SLIPS with good stability by a two-step method. The wettability and stability of SLIPS were investigated, and the results show that the introduction of mesoporous silica inorganic nanoparticles enhanced the performance of SLIPS. Among them, the sliding angle of polyimide SLIPS with a nanoparticle content of 10% is 2°, which has good self-cleaning performance, antifouling performance, and stability.

Superhydrophobic/oleophilic coating was prepared on steel via wet chemical etching, and followed by surface modification. Surface grafting was manifested to be realized mainly on the oxidized area. Slippery liquid infused porous surface(s) (SLIPS) was prepared by infusing perfluorinated lubricant into the prepared superhydrophobic coating, to repel water, coffee, kerosene, and even hexane, suggesting a transition from superoleophilicity to lyophobicity. Furthermore, the lyohobicity was accessible only when the substrate is fluorinated. Moreover, the kinematic viscosity was demonstrated to be negatively correlated to the traveling speed of the liquids on the SLIPS.

Recently, slippery liquid-infused porous surface (SLIPS) is widely utilized for anti-icing. Nevertheless, a major challenge hindering the practical applications of SLIPS is the depletion of lubricating oil, significantly deteriorating its deicing performance. Given that super-slippery effects are not required during most non-icing periods, this research introduces a novel dynamic wettability-adjustable SLIPS anti-icing coating inspired by the nepenthes. This coating-comprising modified diatomaceous earth and soft silicone rubber-releases lubricating oil only when temperatures fall below −2 °C, thus exhibiting super-slippery characteristics and effectively preventing icing. The porous modified diatomaceous earth retains lubricating oil for prolonged periods and facilitates its controlled release under external forces. The high elasticity and strength of the soft silicone rubber endow the coating with thermal expansion and contraction capabilities, enabling the active absorption and release of lubricating fluid in response to temperature variations. This coating, prepared using a straightforward strategy, demonstrates an ice adhesion strength and an oil loss rate of less than 23 kPa and 13%, respectively, after 50 icing/de-icing cycles. These findings highlight the remarkable performance of the coating, providing valuable insights for achieving long-term anti-icing on the external surfaces of equipment in extreme working conditions.

Superhydrophobic surfaces with high water contact angles and low slide angles have drawn worldwide attention for their excellent water resistance, anti-contamination, and self-cleaning property. Herein, hydrophobic coatings were facilely fabricated on porous glass fiber nonwoven mats through immersing the substrates in a highly fluorinated emulsion, which was prepared with cross-linkable sulfonyl macro emulsifiers. The superhydrophobic properties and the long term stability of porous glass fiber mats were optimized by incorporating the synthesized emulsion and cross-linking agents, Melcross 03, together into the coating process. Notably, the superhydrophobicity of modified glass fibers can be ascribed to the surface enrichment of fluorine and lack of migration from reacted polar sulfonyl groups. As a result, the largest water contact angle of the coated glass fiber obtained is 151.4° and the smallest slide angle measured is only 3.9°, exhibiting superior water repellency to other fluorinated emulsion coatings. Moreover, the great anti-fouling properties and water/oil separation performance suggest that the facile method is promising for varied applications.

With the increasingly strict requirements for marine environmental protection, the demand for antifouling coatings that can replace organotin is becoming more urgent. Here, environmentally friendly lubricants were infused into porous surfaces to obtain antifouling coating. The stability of the coating was evaluated by the contact angle and sliding angle tests. The antifouling performance was intuitively represented by the adhesion quantity of three marine algae. The adhesion experiment showed that a lubricating oil of suitable viscosity balanced stability and lubricity, so that the silicone oil (PMX200-100)-infused surface showed the best antifouling effect. However, it was covered by Navicula exigua (N. exigua) after a long time of immersion. In our work, the grease-infused surface displayed outstanding stability in water. In addition, the grease-infused porous surface showed another state of algae attachment after a period of immersion in algae solution. Algae adhered to the surface and congregated to form a layer of biofilm , but it could be easily removed and re-expose the new grease-infused surface. The requirement of lubricating grease for porous surface structures is not as high as that of lubricating oil. The grease-infused surface has a long-term circulation antifouling effect on algae.

Functional materials with specific wettability have broad technological implications in various fields. Herein, inspired by the rapid replenishment of Nepenthes nectaries, we present novel lubricant infused hierarchical porous surfaces with self-replenishing and self-reporting capacities. As the porous surfaces were replicated from colloidal co-assembly templates, they were composed of an inverse opal nano-porous structured outer surface layer to lock the lubricant and maintain the surface stability, together with an embedded macro-porous network as reservoirs to store and supply the lubricant for self-healing. We have demonstrated that the hierarchical inverse opal films are in possess of liquid-repelling feature on liquids with different surface tensions (22.3 mN/m to 72.8 mN/m) and favorable self-replenishment capacity for stable droplet manipulation. In addition, the structural colors arisen from the periodic nanostructure could serve as an optical indicator to monitor the wettability of the resultant slippery surfaces, thus greatly expanding their practical values. These features make the self-replenishing slippery surfaces ideal candidates for various applications such as optical sensing, fluid transportation, medical self-cleaning, and so on.

Membrane distillation (MD), as a new separation technology, has shown great potential in seawater desalination, food concentration, and industrial wastewater treatment . However, traditional polymer membranes prepared by non-solvent phase inversion (NIPS) usually obtain relatively denser membrane layer, making it difficult to obtain efficient and stable separation efficiency. Moreover, the complex procedures involved in optimizing the performance of Poly (vinylidene fluoride) (PVDF) membranes, such as additives and their extra costs, are two obstacles to large-scale application. This work proposed a simple reversion method to obtain PVDF membrane with a highly porous surface by delaying the phase inversion velocity. Furthermore, the effects of different polymer concentrations on the membrane structures and performances were explored. It was demonstrated that the optimized membranes showed the rejection of 99.9 %, 99 %, and ∼100 % in the MD for saline water, ginseng solution, and dye/salt solutions, respectively. The average water flux was up to 34.8 kg m −2 h −1 in the 35 g/L NaCl solution system and 27.9 kg m −2 h −1 in the 100 g/L NaCl solution system, which demonstrated a significant high-permeance advantage. The membrane flux when treating dye/salt solution and ginseng solution were 22.7–25.4 kg m −2 h −1 and 5.6 to 9.9 kg m −2 h −1 , respectively. This work provided a simple and cost-effective method to fabricate PVDF membranes for separation of saline water, food extracts and dye waste water in the chemical industry.

Slippery liquid-infused porous surfaces (SLIPS) have received growing attention as promising icephobic materials. In this study, SLIPS were prepared on aluminum alloys by combining anodization and infusion of common silicone oil. An SLIPS with low ice-adhesion strength (6 kPa) was obtained by optimizing the anodizing time parameters (10 min). In addition, the frosting process and freezing of water droplets on the as-prepared SLIPS at −10 °C were delayed for 2000 s and 4800 s, respectively. Simultaneously, the as-prepared SLIPS also exhibited excellent anti-icing performance in glaze ice, since the supercooled water drips/ice slipped from the surface. The ice weight of the as-prepared SLIPS was significantly lower than that of the bare aluminum surface and the anti-icing-fluid-coated aluminum surface, which was reduced by 38.2%–63.6% compared with the bare aluminum surface. The ice weight increased with decreased temperature and inclination angle. This work proposes a method suitable for large-area preparation of SLIPS that achieves excellent anti-icing performance and significantly reduces the weight of glaze ice.Keywords:slippery liquid-infused porous surfaces;anti-icing;glaze ice;ice-adhesion strength

Aluminum-based superhydrophobic surfaces are attracting great interest in many fields, such as aerospace, steamship. But the use of these materials in cold conditions has been severely limited because of the inevitable frost and ice formation on the surface. The research shows that the superhydrophobic surface (SHS) cannot realize effective anti-ice, and even the rough structure of the surfaces increases the adhesion force of ice, which brings great difficulty to deice. It is important to prepare a de-icing aluminum-based surface. We successfully prepared a slippery lubricant-infused porous surface, which not only has the self-cleaning property, non-infiltration and durability like the SHS, but also has the obvious effect of postponing the freezing, and more importantly, it has obvious advantages in passive defrosting, compared with SHS.

Marine engineering materials face the challenges of corrosion and biofouling. In this study, a graphene nanofluid has been prepared by dispersing modified graphene in a common lubricant. Porous surfaces on Q235 carbon steel have been generated by applying the highly efficient texturing method—breath figure method and then infused with the graphene nanofluid. The coating thus obtained showed high stability, reduced oil-phase leaching, and a self-healing function. Moreover, the slippery coating exhibited a more than five orders of magnitude superior anti-corrosion performance and improved anti-biofouling properties. The developed graphene nanofluid coating has great potential for applications involving the protection of surfaces exposed to the marine environment.
