The adsorption and aggregation of 2-hydroxyl-propanediyl-α,ω-bis(dimethyldodecyl ammonium bromide) (abbreviated as 12-3(OH)-12) in aqueous solution have been investigated by equilibrium and dynamic surface tension, surface dilational rheology, conductivity, fluorescence probing, viscosity, zeta potential and dynamic light scattering measurements. The results measured by dynamic surface tension, molar...
The adsorption of alkanediyl-α,ω-bis(dimethyldodecylammonium bromide) (referred to as 12-s-12, s=12, 14 and 16) at the air/water interface in the absence and the presence of 10mmolL −1 NaBr has been investigated using surface tension measurements. The addition of salt strongly promoted the adsorption of 12-s-12, resulting in the formation of the double layers in the subphase below the main...
