General description

1-Octadecanethiol (ODT) is an alkanethiol with a long carbon chain mainly used as a self-assembled monolayer (SAM) for surface modification of a wide range of materials. It facilitates superhydrophobicity with high wettability and low surface energy.[1][2]

Application

ODT is used in the surface modification of gold nanoparticle (AuNPs)/Nickel (Ni) foam conjugate for the preparation of a 3D surface enhanced Raman spectroscopy(SERS) substrate for the detection of organic pollutants.[3] It may also be used enhance the superhydrophobic properties for different materials like nano-sized copper films,[4] graphene and silica for different applications like mercury detection and electrochemical analysis.[5][1]
