A Self-Oscillating Polymer Chain with High LCST
A novel self-oscillating polymer displaying a high lower critical solution temperature (LCST) was developed. The novel polymer chain underwent soluble-insoluble self-oscillation induced by a Belousov–Zhabotinsky reaction. The driving force of the self-oscillation was the differing solubility of the polymer chain in the reduced and oxidized states. The amplitude of self-oscillation was hardly affected by the concentration of the oxidant, sodium bromate. In addition, the period of the polymer solution could be controlled by careful selection of the concentration of the sodium bromate.
