Smart worm-like micelles responsive to CO2/N2 and light dual stimuli†
Abstract
CO2/N2 and light dual stimuli-responsive worm-like micelles (WLMs) were obtained by addition of a relatively small amount of a switchable surfactant, 4-butyl-4′-(4-N,N-dimethylhexyloxy-amine) azobenzene bicarbonate (AZO-B6-CO2), sensitive to the same triggers to a binary aqueous solution of cetyltrimethylammonium bromide (CTAB) and sodium salicylate (NaSal).
