Background
From the 20 th century, the corrosion inhibitor corrosion prevention method is widely applied to the industries of petrifaction, maritime industry and the like due to the advantages of low cost, simple process, excellent corrosion prevention effect and the like.
The surface of the carbon dot contains a large number of active groups such as carboxyl and hydroxyl, so that the carbon dot can be modified, and the coordination capacity of the carbon dot and the metal surface is enhanced by introducing heteroatoms, so that the corrosion inhibition effect of the carbon dot is improved. The adsorption of the modified carbon point corrosion inhibitor is beneficial to reducing the contact of the surface of the metal with a corrosive medium, and can effectively inhibit the corrosive medium from diffusing to the surface of the metal.
The synthesized carbon point corrosion inhibitor generally adopts a hydrothermal synthesis method. One is a two-step synthesis method, firstly, a carbon dot solution is obtained by carbonization in a reaction kettle through a hydrothermal method, and then functionalized molecules are modified on active functional groups to prepare the carbon dot corrosion inhibitor. One is a one-step synthesis method, which is used for directly synthesizing heteroatom-doped carbon point corrosion inhibitor in a reaction kettle by a hydrothermal method as raw materials of a carbon source, a nitrogen source or a sulfur source. The method for evaluating the corrosion inhibitor is more complete, and the common methods comprise a weight loss method, electrochemical measurement, micro-morphology and component characterization and the like.
Most of the carbon point corrosion inhibitors reported at present use citric acid, ammonium citrate, aminosalicylic acid and the like as carbon sources, and the synthesized carbon point corrosion inhibitors have poor corrosion inhibition effect.
