The amphiphobic materials were prepared based on a steel sheet by means of Michael reaction of dopamine and siloxane according to mussel-inspired chemistry.The structure of the amphiphobic materials was characterized by SEM,FTIR,and contact angle tests.Besides,their properties were tested.The results show that the amphiphobic materials possess high hydro-oleophobicity properties;the contact angles of water and oil droplets on the amphiphobic material surface were 158° and 128°.Amphiphobic materials show excellent wear resistance,mechanical durability properties,chemical stability,and heat resistance in crude oil and have a high application prospect in complex crude oil pipeline transportation environments.
