我们研究了有机酸作为燃料驱动的聚合物链的透射率自振荡。自振荡聚合物链由 4-丙烯酰吗啉 (ACMO) 和 Belousov-Zhabotinsky (BZ) 反应的 Ru 催化剂 (Ru (bpy) 3) 组成。透射率自振荡行为受温度影响显着。随着聚集态反映的透射率自振荡的幅度随着时间的推移而减小，振荡周期也减小。这一趋势表明聚合物聚集显着影响 BZ 反应速率。自振荡值的活化能与正常BZ反应几乎相同，该反应在聚合物链中不包含Ru(bpy) 3 配合物。此外，我们还证明了一种 BZ 底物（溴酸钠或丙二酸）对透射率自振荡周期的影响。
We studied the transmittance self-oscillation of a polymer chain driven by an organic acid as the fuel. The self-oscillating polymer chain consists of 4-acryloylmorpholine (ACMO) and the Ru catalyst (Ru (bpy) 3) of the Belousov–Zhabotinsky (BZ) reaction. The transmittance self-oscillating behavior was affected significantly by the temperature. As the amplitude of the transmittance self-oscillation, which is reflected by the aggregation state, decreased with time, the oscillation period also decreased. This trend indicates that the polymer aggregation affects the rate of the BZ reaction significantly. The activation energy of the self-oscillating value was almost the same in the normal BZ reaction, which does not include Ru (bpy) 3 complexes in the polymer chains. In addition, we demonstrated the effect of one BZ substrate (sodium bromate or malonic acid) on the transmittance self-oscillation period.
