In this paper, mixed micelle composed of alcohol and polymerizable surfactant (surfmer) were constructed. The aggregated numbers of surfmer (hexadecyl trimethyl allylammonium chloride (C16DMAAC)) in the mixed micelle were measured using a steady-state fluorescence quenching (SSFQ) technique. Using a mixed micellar method with adiabatic polymerization and post-hydrolyzation techniques, the high molecular weight (Mw) micro-block associative polymer of P(AM-NaAA-C16DMAAC) was polymerized. Structures were characterized by Fourier transform-infrared (FT-IR) spectroscopy and 13 C nuclear magnetic resonance (NMR) spectroscopy. Using rheological experiments, the effects of micro-block length and salt concentration of on the thickening and viscoelastic rheological properties of the polymers were studied. All experiments confirmed that the micro-block length could be adjusted using the mixed micellar method. Increases in the micro-block length were accompanied by decreases in the critical associative concentration (CAC). The viscosities and viscoelastic rheological properties increased to maximum then decreased steady with the length increasing, indicating that the length was at an optimum value.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
