A superhydrophobic cotton fabric is prepared by introducing a commercially available fluorinated acrylate monomer, 1H, 1H, 2H, 2H-nonafluorohexyl-1-acrylate, onto cotton fabric under simultaneous radiation-induced graft polymerization. The superhydrophobic cotton fabric shows good laundering durability, whereby the superhydrophobicity is well kept after 50 individual accelerated launderings, which is equivalent to 250 commercial launderings or domestic launderings.
