Application

Octadecylamine (ODA) is used:
  • To induce hydrophobicity in nanodiamond (ND) powders.
  • In the surface modification of graphite and fullerenes.
  • As a dual source of carbon and nitrogen in the synthesis of N-doped carbon nanotubes (CNTs).
  • To synthesize a single-chain cationic surfactant, bis(amidoethylcarbamoylethyl) octadecylamine.
