“…In comparison with other methods, the technology shows excellent potential due to its various benefits, such as non-pollution, simplicity, high precision and relative rapidity. [152][153][154][155][156][157][158][159][160][161][162][163][164][165][166][167][168][169][170] However, some stubborn problems originating from this technology and the membrane itself still persist. From the perspective of femtosecond laser microfabrication technology, the products prepared via a femtosecond laser are always unstable, e.g., the surface wettability induced by a femtosecond laser may change over a period of time.…”

“…The interfacial strategies involve an interface (e.g., gas–liquid and gas–solid) within the membrane, of which the modification only occurs at one side. Mussel-inspired single-sided deposition is one of the most facile interfacial strategies that has been widely applied in Janus membrane fabrication. ,− During this process, a hydrophobic membrane is floated on a dopamine-containing solution, for example, the dopamine/PEI solution, and PDA/PEI is deposited on the surface contacting with the solution . The hydrophobic membrane provides a stable air–water interface, and PDA can adhere to the hydrophobic surface from an aqueous solution.…”

Surface and interface engineering provides a powerful tool to tailor the structures and properties of polymer membranes, sharpening their applications in sustainable development. Tremendous progress has been achieved in this field over the past 20 years. In this Perspective, we overview the conventional and emerging strategies for membrane surface engineering and present the current trends in surface and interface engineering for both porous and thin-film composite membranes. For porous membranes, the rise of Janus membranes motivates the evolution from uniform functionalization to asymmetric performance construction. For thin-film composite membranes, the research foci are moving to the surface modification of substrates, the fabrication of nanostructured interlayers, and especially the regulation of interfacial polymerization.

The transport of liquid droplets plays an essential role in various applications. Modulating the wettability of the material surface is crucial in transporting droplets without external energy, adhesion loss, or intense controllability requirements. Although several studies have investigated droplet manipulation, its design principles have not been categorized considering the mechanical perspective. This review categorizes liquid droplet transport strategies based on wettability modulation into those involving (i) application of driving force to a droplet on non-sticking surfaces, (ii) formation of gradient surface chemistry/structure, and (iii) formation of anisotropic surface chemistry/structure. Accordingly, reported biological and artificial examples, cutting-edge applications, and future perspectives are summarized.
