以酚醛树脂为前体,表面活性剂F127为软模板,通过蒸发诱导自组装法制备了有序介孔聚合物,将其水热负载氢氧化镁并在高温下进行碳化得到具有有序介孔结构和丰富活性氧基团的有序介孔炭材料。系统研究了水热浸渍温度对所得材料表面积、孔体积及超级电容器性能的影响。结果表明:随着温度的升高,氢氧化镁负载量升高,但其表面积下降,最佳的水热浸渍温度为150℃,在该温度下水热浸渍的氢氧化镁的负载质量为3.3%,所得材料的表面积为326m2/g,其作为电极用于超级电容器的容量为212F/g。
Ordered mesoporous polymer was fabricated by an evaporation induced self-assembly method with soluble phenolic resin as precursor and surfactant of F127 as template.The derived mesoporous polymer was further treated to loading magnesium hydroxide and then carbonized to obtain the mesoporous carbon with ordered mesoporosity and rich electroactive oxygen functionalities.The effect of hydrothermal treatment temperature on the surface area,pore volume and supercapacitive performance of the resulting carbon was systematically investigated.The results showed that the loading amount increased as the rise of hydrothermal temperature,but the surface area of the derived mesoporous carbon would decreased.Systematically investigation showed that the optimal hydrothermal impregnation temperature was 150℃,at this temperature the loading amount was 3.3wt%,the derived mesoporous carbon owned surface area of 326m2/g and achieved a capacitance of 212F/g as electrode for supercapacitor.
