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.
