Variation of characteristics of pentaoxyethylene decyl [C.sub.10][E.sub.5] and hexaoxyethylene tetradecyl [C.sub.14][E.sub.6] ether micelles with uptake of n-octanol

Article Abstract:

Static (SLS) and dynamic light scattering (DLS) experiments were conducted to examine effects of uptake of n-octanol on the micellar characteristics of the surfactant pentaoxyethylene decyl [C.sub.10][E.sub.5] and hexaoxyethylene tetradecyl [C.sub.14][E.sub.6] ethers. It was found that the micellar length increases with increasing surfactant weight fraction and increasing n-octanol content in the micelles or with increasing temperature.

Wormlike micelles of polyoxyethylene alkyl ether mixtures [C.sub.10][E.sub.5]{C.sub.14][E.sub.5]{C.sub.14][E.sub.7]: Hydrophobic and hydrophilic chain length dependence of the micellar characteristics

Article Abstract:

The micelles formed with the binary mixtures of surfactant polyoxyethylene alkyl ethers are characterized by static (SLS) and dynamic light scattering (DLS) experiments. It is found that the micellar length increases with increasing concentration or with raising temperature irrespective of the composition of the surfactant mixtures.
