Abstract
The ability to modulate the viscoelastic behavior of wormlike micellar systems with smart features is of great importance in both fundamental and applied science. In this paper, the novel triple stimuli-responsive (pH, temperature and light) wormlike micellar system is formed by mixing a cationic surfactant, 3-hexadecyloxy-2-hydroxypropyltrimethylammonium bromide (R16HTAB) and sodium trans-o-methoxycinnamic acid (NaOMCA) in aqueous solutions. The rheological techniques, nuclear magnetic resonance (1H NMR) spectroscopy, Fourier transform infrared (FTIR) spectroscopy and cryogenic-transmission electron microscopy (cryo-TEM) were employed to demonstrate the multi-responsive behaviors of wormlike micellar systems. The rheological properties of wormlike micelles systems were studied under three trigger conditions (pH, temperatures, and UV irradiation), and the mechanism of multiple-responsiveness was discussed in detail by a combination of 1H NMR, FTIR and cryo-TEM. It was found that the viscoelastic behavior of a mixed system was reversible under different excitation conditions. We hope that the study of this triple response system can provide new theoretical foundation for future applications.
