Beschreibung

Anwendung

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.
