Dodecylphosphonic acid is widely used in surface modification and corrosion inhibition. It forms self-assembled monolayers on metal surfaces, particularly aluminum and steel, enhancing their resistance to oxidation and wear. This property makes it valuable in coatings for industrial equipment and automotive parts. Additionally, it is employed in the production of lubricants to reduce friction and improve durability. In the electronics industry, it serves as a key component in the fabrication of thin films and organic semiconductors, aiding in the development of advanced electronic devices. Its ability to bind to metal oxides also makes it useful in water treatment processes for removing heavy metals from wastewater.
