Application

Didodecyldimethylammonium bromide (DDAB) is a double-chain cationic surfactant.

Possible applications:
  • DDAB can be employed as a co-surfactant to synthesize well-defined multilamellar vesicular silica with an adjustable number of layers.
  • As a surfactant to synthesize gold nanoclusters and nanocubes.
  • It forms supersaturated reverse micelles and microemulsions that act as organized reaction microenvironments for the synthesis of barium sulfate.
  • Calcium montmorillonite can be modified by DDAB through direct ion-exchange to synthesize thermally stable organoclay.
