Application
Didodecyldimethylammonium bromide (DDAB) is a double-chain cationic surfactant.
Possible applications:
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.
