In this paper, a facile one-pot synthesis method was reported to fabricate multifunctional superhydrophobic composite materials with remarkable mechanochemical robustness, stain repellency, oilwater separation and sound-absorption. Their mechanical and chemical durability could be greatly improved by chemically adhering epoxy resin microspheres (ERMs) on 3-D porous skeleton structures of latex sponge. The materials could retain superhydrophobicity after going through sandpaper abrasion, ultrasonication, multiple knife scratch, tape peeling and fnger wiping, and exposure to UV irradiation and high temperature. The materials are able to maintain the repellency against strong acid and alkali.
