Durable superhydrophobic cotton fabric decorated with pyrogallol-based polybenzoxazine and Fe3O4 for effective oil–water mixtures and emulsions separation

Advancing coatings with polybenzoxazines: insights into molecular design, synthesis, and modification

“…This fabric exhibited a WCA of 154° and an oil/water separation efficiency exceeding 99.8%. 126 The micro/nano Fe 3 O 4 particles enhanced the surface roughness of cotton fabric, facilitating the establishment of coordination bonds between Fe 2+ and Fe 3+ and N/O atoms in PBZ and cotton fabric. Additionally, the fabric demonstrated exceptional mechanical and chemical stability, along with remarkable self-cleaning capabilities.…”
