Usage
1-Dodecanethiol (1-DDT), also known as n-dodecyl mercaptan or lauryl mercaptan, is a versatile compound with a range of applications. It is primarily used as a chain transfer agent in radical polymerization, a polymerization inhibitor, and as a reagent in the synthesis of metal nanoparticles and self-assembled monolayers (SAMs).
Here’s a more detailed breakdown of its uses:
1. Polymer Industry:
-
Chain Transfer Agent:1-DDT is used to control the molecular weight and polydispersity of polymers during radical polymerization.
-
Polymerization Inhibitor:
It prevents unwanted polymerization reactions in polyurethane resins and neoprene adhesives, particularly in applications like footwear.
2. Nanotechnology:
-
Metal Nanoparticle Synthesis:
1-DDT is a key reagent for synthesizing thiol-stabilized metal nanoparticles, including gold and silver nanoparticles.
-
Ligand for Nanocrystals:
It acts as a coordinating ligand in the synthesis of Cu2ZnSnS4 (CZTS) nanocrystals and as a capping ligand for copper sulfide nanoparticles (Cu2S).
3. Surface Modification:
- Self-Assembled Monolayers (SAMs): 1-DDT is used to create hydrophobic or mixed SAMs on various surfaces, enabling applications in surface modification and the creation of molecular devices.
- Corrosion Resistant Coating: It can form a SAM on copper surfaces to provide corrosion resistance.
