Tethered-liquid perfluorocarbons (TLPs) are a class of liquid-infused surfaces with the ability to reduce blood clot formation (thrombosis) on blood-contacting medical devices. TLP comprises a tethered perfluorocarbon (TP) infused with a liquid perfluorocarbon (LP); this LP must be retained to maintain the antithrombotic properties of the layer. However, the stability of the LP layer remains in question, particularly for medical devices under blood flow.

Introduction A droplet of water easily glides across the surface of a thick oil layer due to negligible interfacial friction and the absence of defects. This frictionless scenario can be replicated on solid surfaces by trapping an infused interfacial layer of air (as in superhydrophobic surfaces),1 or of oil (as in lubricant-infused surfaces)2 using micro- and nano-textures.

Abstract Slippery covalently-attached liquid surfaces (SCALS) with low contact angle hysteresis (CAH, <5◦) and nanoscale thickness display impressive anti-adhesive properties, similar to lubricant-infused surfaces. Their efficacy is generally attributed to theliquid-like mobility of the constituent tethered chains. However, the precise physico-chemical properties that facilitate this mobility areunknown, hindering rational design.
