With the soft melamine foam as the base material and methyl trichlorosilane as the modifier, melamine modified foam containing two-dimensional polysiloxane coating and three-dimensional porous network framework structure was successfully prepared by chemical vapor deposition. This unique structure gave melamine modified foam excellent hydrophobic, oil-water separation, oil absorption and flame-retardant properties. The water contact angle, oil absorption, oxygen index reached 114(°), 155.6 g/g and 38.5% and the heat release rate, peak heat release rate and total heat release decreased by 57.4%, 59.5% and 31.1%, respectively. The design and preparation of melamine modified foam with unique structure, excellent hydrophobic and flame-retardant properties provide a new way for the design of multifunctional oil-water separation materials and the solution of oil pollution problems in the future.

Key words: Melamine foam, Polysiloxane coating, Hydrophobic, Flame-retardant properties
