For applications of block copolymer mixtures as potential new nano-vehicles for delivery, understanding the components mixing characteristics are of special interest. In our previous study [1], we showed that interactions between a biological charged diblock-copolymer like protein, betacasein, and a synthetic uncharged synthetic triblock copolymer, Lutrol F-127, lead to the formation of mixed m...

Abstract Surfactants exist in atmospheric aerosols mixed with inorganic salts and can significantly influence the formation of cloud droplets due to bulk–surface partitioning surface tension depression. To model these processes, we need continuous parametrizations concentration dependent properties aqueous surfactant–salt solutions for full composition range from pure water surfactant or salt. ...

The mixed micellization of adiphenine hydrochloride (ADP) with 1-decyl-3-methylimidazolium chloride (C10mim.Cl), was investigated at different mole fractions and temperatures by surface tension measurements. The synergistic behavior (i.e., non-ideal behavior) for binary mixtures was explained by the deviation of critical micelle concentration (cmc) from ideal critical micelle concentration (cmc...

Amphiphilic ABC triblock copolymers composed of monomethoxy-capped poly(ethylene glycol) (MPEG), poly(2-(dimethylamino)ethyl methacrylate) (DMA), and poly(2-(diethylamino)ethyl methacrylate) (DEA) have been synthesized by atom transfer radical polymerization (ATRP). These copolymers dissolve molecularly in acidic aqueous media at room temperature due to protonation of the tertiary amine groups ...

Gel formation by surfactant molecules is argued to be a process similar to micellization rather than crystallization; it is controlled by thermodynamics rather than kinetics. The properties of surfactant-based gels are compared with those of gels with crystalline fibrillar networks, and questions associated with the nature of these gels are raised.
