摘要：

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 CoFe2O4 nanoparticles into the epoxy resin. The modified CoFe2O4 nanoparticles reduce the peak heat release rate, peak smoke production release and CO production in the CoFe2O4/epoxy resin nanocomposite by 39.6, 41.6, and 61.3%, respectively. The obtained flame retardant CoFe2O4/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.
