Investigation of Novel Triple-Responsive Wormlike Micelles
Smart wormlike micelles with stimuli-tunable
rheological properties may be useful in a variety of applications,
such as in molecular devices and sensors. The formation of triplestimuli-responsive
systems so far has been a challenging and important issue. In this
work, a novel triplestimuli (photo-, pH-, and thermoresponsive) wormlike
micelle is constructed with <i>N</i>-cetyl-<i>N</i>-methylmorpholinium bromide and <i>trans</i>-cinnamic acid
(CA). The corresponding multiresponsive behaviors of wormlike micellar
system were revealed using cryogenic transmission electron microscopy,
a rheometer, and <sup>1</sup>H NMR. The rheological properties of
wormlike micellar system under different temperatures, pH conditions,
and UV irradiation times are measured. As confirmed by <sup>1</sup>H NMR, chemical structure of a CA molecule can be altered by the
multiple stimulation from an exotic environment. We expect it to be
a good model for triple-responsive wormlike micelles,
which is helpful to understand the mechanism of triple-responsiveness
and widen their applications
