Halloysite nanotubes loaded with various corrosion inhibitors have been widely used to control corrosion in different fields and sectors, in specific, the oil and gas pipeline industries. One of the main factors to be considered is the loading capacity of the halloysite nanotubes. In this study, Halloysite nanotubes are loaded with various inhibitors like sodium diethyldithiocarbamate, green inhibitors like vanillin, thyme oil and a combination of both vanillin and thyme oil. The end products were characterized by Fourier Transform Infrared Spectroscopy. The formation of end stoppers in the halloysite nanotubes using Copper sulfate was also studied. It is evident from the FTIR analysis that the halloysite nanotubes were efficiently loaded with the corrosion inhibitors and the end stoppers have formed.
