A series of carboxylated carbosilane surfactants with methyl, ethyl, branching CH3-, phenyl, and cyclohexyl (Me-Si2C-COONa, Et-Si2C-COONa, Si2C-La-COONa, Ph-Si2C-COONa, and Cy-Si2C-COONa) were prepared. The effect of isomer and steric hindrance on their micellization in aqueous solution was investigated by surface tension, conductivity, transmission electron microscopy (TEM) and dynamic light scattering (DLS). Si2C-La-COONa with branching CH3- shows a lower gamma CMC value and higher the CMC value compared with Et-Si2C-COONa. Cy-Si2C-COONa with cyclohexyl (41.6 mN m-1) and Ph-Si2C-COONa with p...
