摘要
本论文涉及一种制备一维大孔碳材料及控制其孔隙率的方法。采用静电纺丝技术和无机纳米粒子模板辅助方法制备得到聚合物纤维并经碳化等后处理工艺得到相关多孔碳材料~([1,2])。图1为采用二氧化锡(SnO_2)或二氧化硅(SiO_2)微球为模板制得的多孔纳米碳纤维。获得的多孔纳米碳纤维具有比表面积高、孔道结构丰富、孔径可调等特点,可作为电极材料应用于锂离子电池、超级电容器中,也可用作吸附剂或催化剂载体。
Hierarchical porous carbon nanofiber materials with tailored pore size are prepared by a combination of electrospinning and sacrificial template method. The obtained carbon materials can be used directly as the self-supporting electrodes for batteries or supercapacitor, which benefit from a large percentage of micropores and surface area as well as better interfacial contact and the shortened diffusion length. Furthermore, the impressing performance can also expand their applications to adsorbent and catalyst carrier.
