Effect of Concentration of Nitric Acid on the Autonomous Conformation Change of a Polymer Chainwith Nonthermoresponsivenature
In this paper, theeffect of the initial concentrationof nitric acidon the soluble-insoluble self-oscillation for a novel polymer chainwith nonthermoresponsive nature was investigated. The self-oscillationoccurs induced by the Belousov-Zhabotinsky (BZ) reaction. In the condition of [HNO3] = 0.1 M, no transmittance self-oscillation occurs. In addition, in thecondition of [HNO3] = 0.2 M, the life-time of the self-oscillation is significantly short. This is because the solution pH much affects the BZ reaction. Moreover, we demonstrated that the period of the transmittance self-oscillation decreases with the increase in the temperaturein accordance with the Arrenius equation.
