Slippery liquid-infused porous surfaces (SLIPS) derived smart windows (SWs) that dynamically fine-tune the solar spectrum are promising candidates for alleviating the global energy crisis, especially for dim rainy climates. Unfortunately, the inferior durability, high energy-consumption, and slow tune-responsivity over SLIPS-based SWs greatly hinder their practical usage. Reported is an ultrarobust omni-liquid-repellent magnetism-actuated reconfigurable microshutters (OLR-MARS) via integrating a femtosecond laser ablation and soft-lithography technique. By alternately loading/discharging a remote magnet, OLR-MARS can be reversibly switched between a transparent mode and an opaque mode within 0.03 s, which is far sensitive than the previously-reported SWs. Simultaneously, OLR-MARS can harness the surface liquids between a slippery state (the sliding angle of ≈15^o) and a sticky one (pinning at a tilt angle of 90^o). Significantly, owing to its all-solid-state merit, OLR-MARS demonstrates good longevity even when subjected to the raindrops impact above 1000 cycles. Results indicate dual switching over the interfacial hydrodynamics and optics. Last but not least, leveraging the optimized OLR-MARS, encryption-decryption, thermal management, and an angle-dependent privacy-screen is deployed. Current novel OLR-MARS with robust durability, fast responsivity, and energy-free advantages holds promising potential in self-cleaning smart windows, energy-saving buildings, antivoyeurism, etc.

超耐用全防液智能窗作为高性能润湿性/透明度操纵器，通过激光写入磁驱动微快门实现

光滑液体注入多孔表面（SLIPS）衍生的智能窗户（SW）可以动态微调太阳光谱，是缓解全球能源危机的有希望的候选者，特别是在昏暗多雨的气候下。不幸的是，基于 SLIPS 的软件的耐用性差、能耗高、调谐响应慢，极大地阻碍了它们的实际使用。报道称，通过集成飞秒激光烧蚀和软光刻技术，开发出一种超鲁棒的全斥液磁驱动可重构微快门（OLR-MARS）。通过交替加载/放电远程磁铁，OLR-MARS可以在0.03秒内在透明模式和不透明模式之间可逆切换，这比之前报道的SWs要灵敏得多。同时，OLR-MARS 可以在光滑状态（滑动角约 15 ^{° ）和粘性状态（倾斜角 90}^°固定）之间控制表面液体。值得注意的是，由于其全固态的优点，OLR-MARS 即使经受 1000 次以上的雨滴冲击，也表现出良好的使用寿命。结果表明界面流体动力学和光学的双重切换。最后但并非最不重要的一点是，部署了优化的 OLR-MARS、加密解密、热管理和角度相关的隐私屏幕。目前新型的OLR-MARS具有耐用性强、响应速度快、无能耗等优点，在自清洁智能窗、节能建筑、防窥等领域具有广阔的应用前景。
