TL;DR: Kinetics of the corrosion spot formation at the coating defects was analyzed by the scanning vibrating electrode technique, and an essential damping of corrosion development was demonstrated for halloysite-loaded samples.
Abstract: Halloysite clay nanotubes were investigated as a tubular container for the corrosion inhibitor benzotriazole. Halloysite is a naturally occurring cylindrical clay mineral with an internal diameter in the nanometer range and a length up to several micrometers, yielding a high-aspect-ratio hollow tube structure. Halloysite may be used as an additive in paints to produce a functional composite coating material. A maximum benzotriazole loading of 5% by weight was achieved for clay tubes of 50 nm external diameters and lumen of 15 nm. Variable release rates of the corrosion inhibitor were possible in a range between 5 and 100 h, as was demonstrated by formation of stoppers at tube openings. The anticorrosive performance of the sol-gel coating and paint loaded with 2-5% of halloysite-entrapped benzotriazole was tested on copper and on 2024-aluminum alloy by direct exposure of the metal plates to corrosive media. Kinetics of the corrosion spot formation at the coating defects was analyzed by the scanning vibrating electrode technique, and an essential damping of corrosion development was demonstrated for halloysite-loaded samples.

TL;DR: In this paper, the copper-benzotriazole complexes produced by precipitation in solution were examined and it was shown that the complexes also contain water molecules or hydroxyl ions, and that their structures are modified when other anions are present.
Abstract: Examination of benzotriazole-treated surfaces on copper, and the complexes produced when benzotriazole and analogous compounds react with cuprous and cupric ions in aqueous solution, has shown that the film produced on copper has a polymeric structure and is chemically bonded to the metal or metal-oxide surface Thickness of the surface film is less than 50 A, which complicates elucidation of the film structure. Exploratory work, therefore, has been based upon examination of the copper-benzotriazole complexes produced by precipitation in solution and it has been shown that the complexes also contain water molecules or hydroxyl ions, and that their structures are modified when other anions are present. Other nitrogen-containing heterocyclics also form polymeric complexes with copper, both on the metal surface and in solution, but do not exhibit the strong inhibitor properties of benzotriazole. Benzotriazole is effective for most copper-base materials and affords protection in aqueous and gaseous env...
