The coordination of barrier performance and self\u2010healing ability, however, continues to be difficult. Herein, a polymer coating based on polyethyleneimine (PEI) and polyacrylic acid (PAA) with self\u2010repairing and barrier ability was designed. Introducing the catechol group into the anti\u2010corrosion coating increases the adhesion and self\u2010healing efficiency of the coating, providing a guarantee for the long\u2010term stable bonding between the anti\u2010corrosion coating and the metal substrate. Small molecular weight PAA polymers are added to polymer coatings to increase their self\u2010healing capabilities and corrosion resistance. Because layer\u2010by\u2010layer assembly creates reversible hydrogen bonds and electrostatic bonds that help the coating repair itself when it is damaged, and because the traction of small molecular weight polyacrylic acid speeds up this process. When polyacrylic acid (PAA) with a molecular weight of 2000 was present in the coating at a concentration of 1.5\u2005mg\/mL, the coating\u2018s self\u2010healing capability and corrosion resistance were at their peak.
