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. |
Packaging: | 2, 10 g in glass bottle |
