In recent years, slippery liquid-infused porous surfaces (SLIPSs) have gained significant attention in antifouling applications. However, their performance often deteriorates dynamic environments, limiting service life. TC4 titanium alloy, commonly used hulls and propellers, is prone to biofouling. SLIPSs To address these issues, a novel surface (STASL) was developed on through the integration of hydroxyl end-blocked dimethylsiloxane (OH-PDMS), silane coupling agent (KH550), nano-titanium dioxide loaded with silver particles (TiO2-Ag, anatase) silicone oil, thereby ensuring stable both static conditions. The as-prepared exhibited excellent sliding capabilities for water, acidic, alkaline, saline droplets, achieving speeds up 2.859 cm/s. Notably, STASL demonstrated superior oil retention stability compared SLIPS, particularly at increased rotational speeds. With remarkable self-cleaning properties, significantly reduced adhesion proteins (50.0%), bacteria (77.8%), algae (78.8%) alloy. outstanding has emerged as promising solution mitigating marine biofouling corrosion alloys.

High transparency and durable antifouling surfaces are crucial for Marine applications. However, achieving a long-lasting marine coating that combines both properties high transmittance remains significant challenge. In this study, we present novel high-adhesion, self-healing Slippery Liquid-Infused Porous Surface (SLIPS) with unique three-arm structure, designed from poly(dimethylsiloxane) supramolecular polymer, inspired by the design of natural spider webs. This structure leverages multistrength dynamic hydrogen bonds, including quadruple bond motif, 2-ureido-4-pyrimidinone (UPy) unit. The enhances adhesion providing additional binding sites, which facilitate interactions interfacial groups through rearrangement UPy units. Importantly, exhibits enhanced chain mobility due to placement units on side chains, resulting in efficiency 80% after 24 h underwater environments. performance is substantially higher than coatings main chain, achieve only 30% efficiency. Furthermore, prepared not exhibited improved (∼93.9%) but also demonstrated flexibility, properties, resistance biological contamination. strategy presents promising solution manufacturing multifunctional materials tailored features intricate structures. These demonstrate strong self-cleaning suitable use harsh conditions, applications like windows optical sensor protection.
