Preparation method of benzoxazine super-hydrophobic conductive coating

The invention relates to a preparation method of benzoxazine super-hydrophobic conductive coating, which includes the following steps of dissolving benzoxazine into solvent, adding ketjen black into solution, sufficiently stirring and uniformly dispersing to obtain dispersing solution. By coating rotationally, spraying and casting solution, the dispersing solution is uniformly applied on the surface of a substrate, heated to be cured in a cross linking manner and cooled to obtain the benzoxazine super-hydrophobic conductive coating. The preparation method is convenient, fine in controllability, low in cost and free of complicated chemical treatment, and the coating is fine in hydrophobicity, static contact angle between the coating and the water is larger than 150 degrees, rolling angle between the same is smaller than 5 degrees, and volume resistivity of the coating is smaller than 102 omega cm. Meanwhile, the coating is fine in alkali and acid resistance and solvent resistance and has wide application prospect.
