Used as a surface modifier to create hydrophobic coatings on materials such as glass, silicon, and metals. It forms self-assembled monolayers that reduce surface energy, making it useful in anti-sticking, water-repellent, and corrosion-resistant applications. Commonly applied in microelectronics to passivate surfaces and improve device stability. Also used in the preparation of modified surfaces for lab-on-a-chip devices and in nanotechnology for controlling interfacial properties.
