Photorheology and rheokinetics of CTAB/chlorocinnamic acid micelles
چکیده انگلیسی

The photosensitive micellar system with prospect in drag reduction and heat transfer enhancement has been the research focus of science and industry. In this paper, a new type of photosensitive micellar system formed by cetyl trimethylammonium bromide (CTAB) and trans-chlorocinnamic acid (trans-ClCA) was investigated. The effects of counter-ion concentration, surfactant concentration, UV irradiation time, and the position of substituent groups of counter-ion on photorheological properties were discussed. The results indicate that after UV irradiation the relative viscosity and thixotropy of micellar systems reduce obviously. At the same time, the relative viscosity of micelle systems and concentration of trans-ClCA decline during UV irradiation time. The flow curves of micellar solutions before and after UV irradiation could be described by non-linear co-rotational Jeffreys model correctly. The rheokinetic equation was firstly established to describe the relationship between relative viscosity of micelle systems and conversion of trans-ClCA.
