The flexible manipulation of underwater gas bubbles on solid substrates has attracted considerable research interest from scientists in the fields of water electrolysis, bubble microreactions, drug delivery, and heat transfer. Inspired by the oxygen-binding mechanisms of aquatic organisms, scientists have designed a series of interfacial materials for use in collecting gases, detecting and grading bubbles, and conducting microbubble reactions. Aerophilic surfaces are commonly used in underwater bubble manipulation platforms due to their excellent gas-trapping properties. However, during bubble transport, some of the bubbles are retained in the rough structure of the aerophilic surface and cause gas loss, which in the long run reduces the gas transport function. In addition, the aerophilic surface is prone to failure in high-humidity and high-pressure underwater environments. The lubricant-infused surface features an oil layer that remains stable on a rough substrate and is immiscible with water. Additionally, the bubbles are transported over the oil layer without causing losses other than those dissolved in water. These attributes make it more favorable than the aerophilic surface. Inspired by the unique properties of Nepenthes and cactus spines, we developed a patterned slippery surface [patterned lubricant-infused surface (PLIS)] through laser etching and ammonia etching that facilitates the coexistence of superaerophobic and aerophilic surfaces. The PLIS executes bubble capture utilizing a difference in wettability measuring 78°, transports bubbles through Laplace force and buoyancy, and regulates bubble release by restricting the contact area on the PLIS. The PLIS can be prepared rapidly and affordably in just about an hour, and its potential for large-scale production is high. Following tests for shear, acid and alkali resistance, and corrosion resistance, the PLIS exhibited impressive weathering resistance and appears to have potential for application in some extreme environments.

We present a biomimetic switchable MXene membrane for water treatment inspired by chloride ion transmembrane transport. The MXene membrane was modified with poly(2-diethylaminoethyl methacrylate), resulting in increased hydrophilicity and enlarged channels. The membrane exhibited a permeability of 4.42 × 104 L m–2 h–1 bar–1, surpassing conventional MXene membranes. The membrane also separated Methylene Blue positively charged at pH = 12 and Amido Black 10B negatively charged at pH = 2 with separation efficiency above 98%, thanks to controllable channel size and adjustable electrostatic interactions in response to pH or CO2. This research offers valuable insights into the design of pH-responsive membranes with adjustable selectivity, representing a significant advancement in smart filtration with versatile applications.

“…People could control the slide direction of the droplets by adjusting the shape of the NIR laser irradiation region. Qian et al [24] reported a slippery laser-induced graphene/polyimide (SLIG/PI) membrane, in which PI nanofiber membranes were prepared using an electrostatic spinning system, followed by laser carbonization of the surface layer of the PI membrane to construct a porous laser-induced graphene (LIG) structure. The lubricant adopted in the SLIG/PI is silicone oil.…”

Photo-responsive slippery lubricant-infused porous surface (SLIPS) for droplet manipulation is flexible, non-contact and non-destructive in droplet manipulation, which has promising applications in flexible robotics, microfluidics, biomedicine, and chemical analysis. However, the repeated manipulations for droplets of SLIPSs are quite limited in the works reported so far, the poor durability of droplet manipulation severely limits the practical application of the surfaces. In this paper, a Fe3O4-doped polydimethylsiloxane (PDMS)-based SLIPS is proposed and implemented to achieve ultra-high repeated droplet manipulation numbers under near-infrared ray (NIR) laser irradiation. Firstly, micron columnar array structure with micro-pits on the top side, as well as, a "wall" structure out of the array were designed on SLIPS to reserve the lubricant. Secondly, the prototype of the SLIPS was fabricated by a 3-step ultraviolet (UV) lithography, and subsequently immersed in silicone oil for more than 96 hours to obtain the ultra-high durability slippery lubricant-infused porous surface (UD-SLIPS). With a power of 25-85 mW NIR laser, the repeated manipulation of microdroplets (≤ 5 μL) in the scale of 1 cm can exceed more than 3000 times which is far beyond that in previous reports. Finally, the droplet manipulation performance of this photo-responsive UD-SLIPS and the influence of infusion time on durability were investigated. The mechanism of the PDMS "swelling" effect was found to be the key factor in improving the droplet manipulation durability of SLIPS. The findings of this work would be of great significance for the development of highly durable photo-responsive functional surfaces for droplet manipulation.
