Fluorine-free liquid-repellent coatings have been highly demanded for a variety of applications. However, rapid formation of coatings possessing outstanding oil repellency and strong bonding ability as well as good mechanical strength (e.g., bendability, impact resistance, and scratch resistance) remains a grand challenge. Herein, a robust strategy to rapidly create fluorine-free oil-repellent coatings in only 30 s via rational design of a semi-interpenetrating polymer network structure is reported. The resulting coating manifests strong bonding capability both in air and underwater. More importantly, it not only provides unprecedented oil repellency, even to high-viscosity crude oil, but also achieves both excellent bendability and hardness. This simple yet effective design strategy opens up a new avenue to manufacture multifunctional materials and devices with desirable features and structural complexities for applications in sustainable antifouling, drag reduction, nondestructive transportation, liquid collection, and biomedicine, among other areas.
无氟拒液涂层在各种应用中有着很高的需求。然而，快速形成具有出色拒油性、强粘结能力以及良好机械强度（如可弯曲性、抗冲击性和耐刮性）的涂层仍然是一个巨大的挑战。在此，报道了一种通过合理设计半互穿聚合物网络结构，仅需30秒就能快速制备无氟拒油涂层的稳健策略。所得涂层在空气和水下均表现出很强的粘结能力。更重要的是，它不仅提供了前所未有的拒油性，甚至对高粘度原油也有拒油效果，而且还兼具出色的可弯曲性和硬度。这种简单而有效的设计策略为制造具有理想特性和结构复杂性的多功能材料及器件开辟了一条新途径，可应用于可持续防污、减阻、无损运输、液体收集和生物医学等诸多领域。
