AI Technical Summary
Technical Problem
In the prior art, corrosion inhibitors commonly used in coatings for preventing metal corrosion, such as chromate, have environmental pollution risks and have limited service life, making it difficult to meet the needs for corrosion resistance and long-term protection.
Method used
A composition is provided, including an epoxy resin, an amino or amido hardener, a polyaniline, a dopant and a pigment, which is coupled to a dopant, capable of releasing the dopant "on demand" in a corrosive environment, providing a self-healing function.
Benefits of technology
The composition can significantly improve the corrosion resistance and barrier properties of metal substrates, extend the service life of the coating, and reduce the risk of pollution to the environment.

Abstract
The present disclosure provides a composition, an article thereof, and a method for forming the composition. In at least one aspect, the composition comprises (1) an epoxy resin; (2) an amino or amido hardener; (3) polyaniline; (4) a dopant selected from a triazole compound, a thiazolyl compound, a quinoline compound, a salicylic acid compound, a benzoic acid compound, an glycolic acid compound, a phosphoric acid compound, a sulfonate, or a combination thereof; and (5) a pigment selected from titanium dioxide, silicon dioxide, talc, mica, aluminum stearate, or a combination thereof. The polyaniline + dopant accounts for less than 6% by weight of the total volume of the composition. The present disclosure provides a substrate having the composition disposed thereon. In at least one aspect, the method comprises introducing an acid form of polyaniline into a hydroxide to form a polyaniline hydroxide. The method comprises introducing a dopant into a polyaniline hydroxide to form a doped polyaniline.
