摘要
本文制备了一种由一维聚丙烯腈基静电纺碳纳米纤维和二维聚酰亚胺基碳纳米片组成的多维度碳气凝胶。[1]这种独特的三维网络结构有利于二氧化锰纳米颗粒的原位生长,从而得到o PP@Mn O_2杂化气凝胶(图1所示)。通过将o PP@Mn O_2和活化的碳气凝胶作为正极和负极材料而组装成非对称超级电容器,其能量密度高达30.3 Wh kg~(-1),极具有商业应用价值。因此,本文中三维静电纺碳气凝胶的成功制备将传统的二维静电纺膜材料拓宽到多维度气凝胶领域,为静电纺丝材料在能量存储领域的开发提供了新思路。
In this study, a fascinating carbon aerogel is rationally designed with unique cellular structure, consisting of one-dimensional oxidized polyacrylonitrile(o-PAN) derived carbon nanofibers and two-dimensional polyimide(PI) originated carbon sheets. The interconnected o-PAN/PI(o PP) carbon aerogel is regarded as an ideal template for in-situ growth of Mn O_2 nanosheets to obtain o PP@Mn O_2 hybrid carbon aerogels as shown in Figure 1. The assembled o PP@Mn O_2//activated o PP(A-o PP) asymmetric supercapacitor delivers a considerably high energy density up to 30.3 Wh kg~(-1). Therefore, the successful fabrication of o PP carbon aerogel expands the traditional electrospun lamellar membranes to multi-dimensional aerogels, providing a new strategy for the construction of nanofiber-based materials toward energy storage.
