In this work, we converted inherently hydrophilic and flammable epoxy resins to resist both fire and water. This was achieved by integrating surface modified flame-retardant CoFeO nanoparticles into the epoxy resin. The modified CoFeO nanoparticles reduce the peak heat release rate, peak smoke production release and CO production in the CoFeO/epoxy resin nanocomposite by 39.6, 41.6, and 61.3%, respectively. The obtained flame retardant CoFeO/EP items demonstrate excellent durability with constant superhydrophobicity even after high external pressure, knife-scratch, and mechanical abrasion. In addition, the obtained items demonstrate outstanding robust water-repellent properties after facing long-term exposure to extremely corrosive liquids and also show self-cleaning properties in air and under oil.
在这项工作中，我们将本质上亲水且易燃的环氧树脂转化为具有防火和防水性能的材料。这是通过将表面改性的阻燃CoFeO纳米颗粒整合到环氧树脂中来实现的。改性后的CoFeO纳米颗粒使CoFeO/环氧树脂纳米复合材料的峰值热释放速率、峰值烟雾产生释放量和CO产生量分别降低了39.6%、41.6%和61.3%。所制备的阻燃CoFeO/EP制品表现出优异的耐久性，即使在高外部压力、刀刮和机械磨损后仍具有恒定的超疏水性。此外，所制备的制品在长期暴露于极具腐蚀性的液体后表现出出色的强防水性能，并且在空气和油下还表现出自清洁性能。
