General description

Octadecylamine (ODA) is a primary alkyl amine mainly used as a hydrophobic surface modifier.

Application

Octadecylamine is used to surface functionalize different carbon nanomaterials (graphene oxide, carbon nanotubes) for different applications which include thin film nanocomposite (TFN) nanofilteration and carbon fiber microelectrodes. It can be used for the preparation of butyrylcholinesterase/stearylamine films (Langmuir-Blodgett films) for use in enzymatic field effect transistor (ENFET) based biosensors. Octadecylamine also forms films which can be used in ion exachnge systems. It may also be used in the preparation of metal oxide nano crystals with controlled size and shape.
