Electron Spin Resonance Study on the Miscibility of Poly(ethylene glycol)With Cationic Dodecyl Trimethylammonium Bromide Micelle

Abstract

The interaction of poly(ethyleneglycol)(PEG) with cationic dodecyl trimethyl ammonium Bromide (DTAB) micelle was studied with electron spin resonance (ESR) by determining line widths of ESR spectra and coupling constant of nitrogen(AN). The degree of ESR line shape change such as line widths coupling constant indicated that PEG mixes well with DTAB micelle due to a great hydrophobic interaction with surfactant alkyl chains. This suggests that the PEG can be used as non-ionic surfactant to disperse the exposed oil in the ocean.
