用途

十二烷基二甲基溴化铵（DDAB）是一种双链阳离子表面活性剂。 可能的应用： DDAB可用作辅助表面活性剂，以合成具有可调层数的明确的多层囊泡二氧化硅。 作为表面活性剂合成金纳米团簇和纳米立方体。 形成过饱和反胶束和微乳液，作为硫酸钡合成的有组织反应微环境。 DDAB可以通过直接离子交换对钙蒙脱石进行改性，以合成热稳定的有机粘土。

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.
