摘　　要：以对苯二酚、甲醛和对甲基苯酚为原料,在酸性条件下通过缩聚反应合成了一种对苯二酚树脂。通过傅里叶变换红外光谱和紫外-可见吸收光谱表征了所得聚合物的结构,采用热失重分析考察了聚合物的热稳定性能,利用循环伏安测试和恒电流充放电测试研究了聚合物的电化学性能。结果表明:合成的聚合物为目标产物,且拥有良好的热稳定性;在0.5 mol/L的Na_(2)SO_(4)溶液中,聚合物发生了可逆的氧化还原反应。在5 mV/s的扫描速率下,其比容量为69.72(mA·h)/g;在0.5 A/g的电流密度下,其比容量为78.23(mA·h)/g,经过100次充放电后,电容量保持率为66.2%,说明具有较高的循环使用寿命。Using hydroquinone,formaldehyde and p-methylphenol as raw materials,a hydroquinone resin was synthesized through a polycondensation reaction under acidic conditions.The structure of the obtained polymer was characterized by Fourier transform infrared spectroscopy and ultraviolet-visible absorption spectroscopy.Thermal stability of the polymers was investigated through thermogravimetric analysis.The electrochemical performance of the polymers was evaluated by cyclic voltammetry and constant current charge and discharge tests.The results show that the synthesized polymer is the target product with excellent thermal stability.In a 0.5 mol/L Na_(2)SO_(4) solution,the polymer undergoes a reversible redox reaction.At a scanning rate of 5 mV/s,the specific capacity is 69.72(mA·h)/g.At a current density of 0.5 A/g,the specific capacitance is 78.23(mA·h)/g,and after 100 charge-discharge cycles,the capacitance retention rate is 66.2%,demonstrating a high cycle life.
