A durable superamphiphobic cotton fabric was obtained by coating SiO2 aerogel particles, polydimethylsiloxane (PDMS), and 1H,1H,2H,2H-perfluorooctyltriethoxysilane (PFTES) on a cotton fabric via the dip-pad-dry process. The surface morphology, chemical composition, and thermal degradation behavior characterization of the as-prepared cotton fabric (PFTES/PDMS/SiO2@Cotton fabric) were performed, respectively. It was proved that the coated cotton fabric was successfully covered with PFTES/PDMS/SiO2. The porous rough surface topology structure due to the SiO2 aerogel particles along with low surface energy because of the fluorinated chains and PDMS adhesive layer on the as-obtained PFTES/PDMS/SiO2@Cotton fabric can trap a layer of air, endowing the coated fabric durable superamphiphobicity. The prepared superamphiphobic cotton fabric with a water contact angle (WCA) of 159.0 ± 0.8° and an oil contact angle (OCA) of 154.5 ± 0.7° showed good liquid repellence for common liquids in daily life like orange juice, cola, coffee, and milk, exhibiting excellent self-cleaning and stain-resistance property. Moreover, the superamphiphobic cotton fabric possessed good durability and still maintained superamphiphobicity after mechanical abrasion for 1500 cycles or ultraviolet (UV) irradiation for 96 h. This superamphiphobic cotton fabric exhibited potential applications in various fields due to the high repellency to various liquids.

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.

Slippery surfaces are highly effective in repelling low-surface tension fluids due to their oleophobicity, anti-adhesive, and drag-reduction properties. However, it should be noted that while these surfaces show promising performance under normal conditions, they may lose their efficacy under harsh conditions, particularly in outdoor applications. In this study, we developed a transparent slippery coating with dual self-healing abilities by a 3D-grafting method. The coating can be formed on various substrates, and the coated glass is highly transparent. Additionally, the coating shows exceptional slipperiness on water and most oils, making it highly effective at repelling liquids. Moreover, the coating exhibits remarkable intrinsic and surface self-healing capabilities, enabling it to restore its slippery effect even in the presence of scratches or damage. This outstanding self-healing property results in a long-lasting, durable coating that can resist wear and tear. The exceptional slipperiness and self-healing properties of coating make them suitable for various industrial, medical, and consumer products.

Given the rapid advancements in ocean engineering, wind power generation, and related fields, it is imperative to develop highly integrated coatings characterized by robust mechanical toughness, efficient self-healing capabilities, and self-cleaning functionalities to prolong the service life of the equipment. However, a formidable challenge encountered in self-healing coatings arises from the inadequate interfacial interaction between the polymer and the substrate, which results from the rapid segmental movement of molecular chains. Furthermore, the integration of multiple functionalities (such as liquid repellency, adhesive capability, scratch resistance, etc.) within self-healing coatings poses a constraint on current development efforts. Herein, we developed a method for preparing fluorine-free biobased water-repellent coatings using eco-friendly plant oils and eugenol. The obtained coatings exhibit excellent intrinsic mechanical performance and extraordinary room temperature autonomous healing efficiency. Remarkably, the coatings also provided unprecedented interfacial strength (shear strength: 11.82 MPa, peeling strength: 1841.4 N m–1) and stable adhesion performance even under water. This judicious design strategy offers a versatile and scalable approach to producing multifunctional coatings and devices tailored for desired functionalities in demanding service conditions. The coatings find application in sustainable antifouling, electronic device protection, and biomedical fields.

Novel photosensitive fluorinated polysiloxane (MA-PNFMS) overhanging with nonafluorohexyl and capped with methacrylate groups were synthesized. The UV-curable coatings were prepared using sulfhydryl functionalized fluorosilicone resin (SFSR) as an additive. The surface chemical composition and morphology, optical properties, adhesion, contact angles and surface energy, liquid repellency, and aging resistance were studied. Results show that the surface energy is as low as 19.0 mN/m, showing excellent liquid repellency. Liquids of varying surface tensions can slide down the inclined surface under gravity without any residue. The adhesion of the coating can reach 4B grade, the transmittance can reach 100%, and the haze is less than 0.6%. Furthermore, the coating also demonstrates excellent aging resistance, and its optical transparency and liquid repellency are maintained after UV and thermal aging. This study shows that MA-PNFMS could be applied as promising protective coatings.

A facile and versatile spin-coating method was adopted to fabricate transparent omniphobic coatings by infiltrating fluorinated lubricant into the uniform polytetrafluoroethylene nanoparticulate film. The lubricant-infused surfaces display excellent liquid repellency, good optical transparency, and show outstanding performance in self-cleaning, anti-corrosion, and anti-icing. Importantly, the liquid repellency of the omniphobic surfaces still prevails after various mechanical damages.

Slippery liquid-infused porous surfaces (SLIPSs) have become an effective method to provide materials with sliding performance and, thus, achieve liquid repellency, through the process of infusing lubricants into the microstructure of the surface. However, the construction of microstructures on high-strength metals is still a significant challenge. Herein, we used a femtosecond laser with a temporally shaped Bessel beam to process NiTi alloy, and created uniform porous structures with a microhole diameter of around 4 µm, in order to store and lock lubricant. In addition, as the lubricant is an important factor that can influence the sliding properties, five different lubricants were selected to prepare the SLIPSs, and were further compared in terms of their sliding behavior. The temperature cycle test and the hydraulic pressure test were implemented to characterize the durability of the samples, and different liquids were used to investigate the possible failure under complex fluid conditions. In general, the prepared SLIPSs exhibited superior liquid repellency. We believe that, in combination with a femtosecond laser, slippery liquid-infused porous surfaces are promising for applications in a wide range of areas.Keywords:SLIPS;femtosecond laser;NiTi alloy;liquid repellency;sliding performance

The extensive application of medical protective polymers has significantly contributed to preserving human lives and well-being. Due to the widespread use of protective polymer materials and their non-degradable nature, environmental and biological pollution issues are becoming increasingly severe. To address the environmental pollution problems caused by traditional polymer materials, this study proposes an efficient and successive method for the mass production of polylactic acid/graphene oxide (MNPG) films with the hunting trap-inspired pyramidal micro/nanostructure by combining micro-extrusion compression molding and electrostatic flocking. The hunting trap-inspired pyramidal micro/nanostructure enhances liquid repellency and antibacterial performance, effectively reducing contaminant adhesion. The MNPG film exhibits an impressive antibacterial efficacy, inhibiting bacterial growth by up to 98.1 %, demonstrating excellent repellency against common liquids, such as blood, bovine serum albumin, milk, and tea, leaving no detectable residue. This provides initial protection against bacterial adhesion and dissemination as well as the spread of pollutants. Importantly, the film retains only 30 wt% of its original mass after 14 days in degradation experiments, indicating favorable biodegradability. This method offers a novel approach for designing sustainable protective materials and holds potential to replace traditional non-degradable polymers.

Slippery surfaces were prepared by infusing lubricant into smooth or hierarchical-structured superhydrophobic surfaces (SHS) to compare different surface-free energies. The surfaces obtained showed good repellency towards liquids with various values of surface tension/molecular polarity/viscosity, including hexane, tetradecane, water, ethylene glycol and viscous engine oil. The lyophobicity could be realized on a relatively smooth surface, indicating that the first principle of preparing a lyophobic slippery surface is to perform a low surface-free energy modification. The dynamic liquid repellency was also studied: the sliding speeds of different liquids on lubricant infused SHS showed a negative correlation to their kinematic viscosity values, and a higher surface roughness was favorable for dynamic wettability, whereas for the smooth slippery surface, the travelling speeds showed randomness.

The excessive use of fluoride in fibrous membranes poses significant bioaccumulative threats to the environment and human health. However, most existing membranes used in protective clothing and desalination systems show high fluorine dependence and inevitable trade-offs between liquid repellency and breathability. Herein, fluorine-free bonded scaffolded nanofiber/network membranes are developed using the electro-coating-netting technique to achieve high-performance liquid-repellency and breathability. By manipulating the stretching of electrospun jets and the polarization of electrets, rough and electrostatic wetting nanofibers are obtained as scaffolds, on which long-chain alkyl precursors are coated to assemble 2D networks consisting of nanowires with diameters of ∼42 nm and bonding points. The resultant fluorine-free membranes exhibit small pore sizes of ∼460 nm, highly interconnected tortuous channels, a water contact angle of ∼138°, and elastic elongation up to 300%, thereby providing both high-performance liquid repellency (125 kPa) and vapor permeability (4206 g m–2 d–1), making them effective for use in protective clothing and desalination. This work could inspire innovative design of ecofriendly nanofibrous materials for high-performance filtration and separation.

The development of robust, stain-resistant, and self-healing liquid-repellent surfaces is a common aspiration of both consumer and industrial applications, but the existing methods suffer from limitations, such as complicated procedures, weak mechanical durability and substrate dependency. In this work, a lubricant-grafted slippery surface (LGSS) was prepared by grafting vinyl-terminated polydimethylsiloxane (Vi-PDMS) onto various substrates coated with sulfhydryl-modified hollow mesoporous silica (SH-HMS) through a thiol-ene click reaction. The uniform and intact lubricant layer can effectively decrease the absorption of the polysaccharide and protein, exhibiting superior antifouling properties. Notably, the hollow structure of SH-HMS could significantly increase the oil grafting capacity of the slippery surface from 0.013 g/cm 2 to 0.027 g/cm 2 compared with the surface constructed by solid silica. By virtue of the strong covalent bond forces between the lubricant oil and surfaces, the obtained LGSS exhibited robust liquid repellency when subjected to high/low temperature, ultraviolet irradiation and water impact. Moreover, the liquid-repellent LGSS exhibited good self-repairing performance owing to the directional migration of the Vi-PDMS chain segment from the hollow capsule to the surface through the mesoporous channels under heating treatment. Therefore, such a newly developed strategy for constructing liquid-repellent coatings on various substrates with self-repairing properties has the potential to promote the advancement of interfacial antifouling materials and exhibit tremendous potential for consumer and industrial applications.

Fluorinated compounds with side-chains longer than six carbon have been banned due to their toxicity to environment, organisms and human, so that attentions have been paid on degradable short-chain fluorinated or non-fluorinated materials. Here in this paper, several novel short-chain fluorinated polysiloxanes with multi-functions were synthesized successfully and applied on cotton fabrics. Chemical structure of these fluorinated polysiloxanes were characterized by Fourier-transform infrared spectrum and nuclear magnetic resonance. Liquid repellency, washing durability, thermal stability, fabric style and color deepening of treated cotton fabrics were investigated. Additionally, the effect of benzoyl spacer on the surface wettability was fully studied. Results demonstrate that FPAPS-20@cotton (cotton fabric treated by fluorinated polysiloxane with 20% fluorine content) exhibits the greatest liquid repellency as the contact angles for water, ethylene glycol, glycerol and octane are 150.1°, 132.3°, 138.1° and 105.5°. Moreover, the benzoyl spacer plays a positive role in the durable wettability of FPAPS-20@cotton, resulting in the water contact angles ranging from 150.1° to 146.0° when FPAPS-20@cotton exposes to the water droplet for 20 min. X-ray photoelectron spectroscopy provides the experimental evidence for this result. On the other hand, thermal-gravimetric analysis confirms that the fluoroalkyl segments of the fluorinated polysiloxanes can decelerate the thermal decomposition of cotton fabrics. Moreover, compared with the untreated dyed cotton fabric, the K/S values of cotton fabrics with navy, red and orange color treated with FPAPS-20 increase by 42.61%, 11.00% and 18.18%, respectively.
