| contents | Liquids flowing against solid surfaces experience friction. While solid friction is familiar to anyone with a sense of touch, liquid friction is much more exotic. At macroscopic scales indeed, the assumption of inifinite friction, i.e. that interfacial liquid molecules stick to solid surfaces, is hard to disprove. Still, it has been known for a few decades that some materials exhibit very strong liquid slippage, leading to a dramatic increase in the permeability of nanoscale tubes to liquid flow. Harnessing liquid friction holds the promise of high-efficiency membrane separation processes, heat recovery systems or blue energy harvesting, making it a highly strategic field for reducing carbon emissions and addressing the climate emergency. In this chapter we review the history of liquid-solid friction measurements, mainly driven by the advent of new techniques and materials. We highlight the most established results and point out some directions that seem to us to be particularly dynamic and promising for the field. |
