摘　　要：以聚苯乙烯微球以及F127嵌段共聚物自组装结构为模板,酚醛树脂低聚物为碳前驱体,双模板法合成了大孔-介孔分级孔结构的炭材料.对样品进行了X射线衍射(XRD)、扫描电镜(SEM)、透射电镜(TEM)和氮吸附-脱附测试,并研究了样品的电化学性能.结果表明,利用这种简便的合成方法可以得到具有三维连通大孔以及二维有序介孔结构的分级孔结构炭材料,大孔尺寸在1μm左右,介孔孔径集中分布在5nm,比表面积为353.8m2/g,孔容0.36cm3/g.利用三电极体系测试了产品作为电化学双电层电容器电极材料的性能,在50mA/g的电流密度下,放电质量比电容为40F/g.Hierarchical macro-mesoporous carbon material（HMMC） was synthesized successfully via a facile dual-templating method using resols as carbon source,in which polystyrene（PS） colloid was selected as macro-porous template and Pluronic F127 as mesoporous template.After thermosetting treatment and carbonization step,HMMC can be obtained.The product was characterized by XRD,SEM,TEM and N2 adsorption techniques.The electrochemical performance of HMMC was evaluated by cyclic voltammetry and galvanostatic charge/discharge methods using an electrochemical workstation and a battery testing system.Results show that HMMC material has three-dimensional connected macroporous structure with pore size of 1μm and ordered mesoporous windows with average pore size of approximately 5nm.BET surface area of the product is 353.8m2/g and pore volume is 0.36cm3/g.The CV curves of HMMC are quasi-rectangular,the specific capacitance of product is calculated to be about 40F/g at a constant current density of 50mA/g.It is anticipated that these novel materials synthesized by the simple methods have potential applications in electrode materials.
