| 摘 要： | 分别以Fe(Cl O4)3、FeCl3、Fe2(SO4)3作为氧化剂,对3′,4′-乙撑二氧-2,2′∶5′,2″-三噻吩(TET)进行了化学氧化聚合,并研究了聚合条件对聚合物结构和电化学性能的影响。利用红外光谱、紫外光谱、X射线衍射对聚合物进行了表征,采用循环伏安、恒电流充放电等电化学方法研究了聚合物的电化学性能。结果表明:当TET与Fe(Cl O4)3的摩尔比为1∶4,反应温度为18℃,反应时间为12 h时,聚3′,4′-乙撑二氧-2,2′∶5′,2″-三噻吩(PTET)具有更好的共轭结构和电化学性能,导电率可达1.47 S/m,比电容可达133 F/g。

| Abstract: | 3',4'-Ethylenedioxy-2,2':5',2"-Terthiophene(TET)was synthesized by oxidation polymerization with different oxidants(Fe(ClO_4)_3、FeCl_3、Fe2(SO_4)_3).The effect of reaction conditions such as oxidant concentration,reaction time and temperature on the property of final polymers were investigated.The polymers were characterized by UV-Vis,FT-IR,XRD.The electrochemical behaviors of the polymes were evaluated by cyclic voltammetry(CV)and galvanostatic charge-discharge tests.Results show that PTET has the highest conductivity of 1.47 S/m and the specific capacitance of 133 F/g while Fe(ClO_4)_3(mole ratio of TET and Fe(ClO_4)_3 was 1:4)was used as an oxidant and the polymerization was proceeded for 12 h at 18℃. |
