Abstract:

Amphiphilic polymers prepared from natural biological polysaccharides can expand macromolecular self-assembly to practical applications. In this study, the assembly behavior and emulsification property of dopamine modified sodium hyaluronate were studied by changing the strength and type of ions in the system. The results indicate that the dopamine modified sodium hyaluronate self-assembles to form nanoparticles in aqueous solution and adsorbs at the oil-water interface, which can be used to stabilize the emulsion. Dopamine modified sodium hyaluronate exhibits different assembly behaviors and emulsification properties due to the electrostatic and chelating effects of sodium and manganese ions, respectively. As the concentration of sodium ions increases in the system, the size of polymer particles decreases, the emulsification property decreases, and the size of the emulsion droplets increases. In contract, the size of polymer particles decreases with the increasing of the concentration of manganese ions, which results that the emulsification performance increases and the droplets size decreases.

Key words: ionic coordination, dopamine, sodium hyaluronate, self-assembly
