单壁碳纳米管（SWCNT）阴离子可以通过亲电介质交联形成共价的碳键合有机凝胶。冷冻干燥产生具有低密度（2.3 mg cm（-3））、高表面积（766 m（2）g（-1））和高电导率（9.4 S m（-1））的冷冻凝胶，显示出作为超级电容器电极的前景。反离子浓度控制着解束、接枝率以及所有所得的性质。
Single-walled carbon nanotube (SWCNT) anions can be cross-linked by a dielectrophile to form covalent, carbon-bonded organogels. Freeze-drying produces cryogels with low density (2.3 mg cm(-3)), high surface area (766 m(2) g(-1)), and high conductivity (9.4 S m(-1)), showing promise as supercapacitor electrodes. Counterion concentration controls debundling, grafting ratio, as well as all the resulting properties.
