Uses
Organic intermediate, synthetic rubber processing. 1-Octadecanethiol (ODT) is used to deposit thiolated molecules onto the surface of gold substrates, such as SAMs on gold quartz crystal resonators, on the tip of atomic force microscope probes, capacitive sensors. 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. It may also be used enhance the superhydrophobic properties for different materials like nano-sized copper films, graphene and silica for different applications like mercury detection and electrochemical analysis.
