Construction of environmentally durable, flame-retardant, and superhydrophobic melamine sponge functionalized with polydopamine and octadecyltrichlorosilane for efficient oil-water separation

Key Points

• The aim is to develop a superhydrophobic melamine sponge that is durable and flame-retardant for effective oil-water separation.
• Constructed superhydrophobic coatings using polydopamine and octadecyltrichlorosilane.
• Evaluated interfacial behaviors of oil and water on the sponge surface.
• Assessed efficiency for oil-water separation applications.
• Demonstrated successful creation of durable superhydrophobic coatings.
• Achieved significant improvement in oil-water separation efficiency.
• Confirmed flame-retardant properties of the functionalized sponge.
