摘要
随着柔性可穿戴概念的兴起,对柔性储能器件提出了越来越高的要求。浮动化学气相沉积碳纳米管薄膜集导电、高表面积、柔韧、高力学强度等特性于一体,是理想的柔性储能器件电极材料载体。本文从浮动化学气相沉积薄膜可控制备、高效功能化及柔性超级电容器等方面进行论述,揭示其在柔性储能领域的潜在应用。(1)调控浮动化学气相沉积生长温度等参数,可控制碳纳米管管径与聚集状态等关键要素,实现碳纳米管薄膜的连续高效制备;(2)针对碳纳米管薄膜疏水特性,以电化学阳极氧化法对其进行功能化,此过程中碳纳米管被氧化从而提高了亲水性,而产生的氧气气泡膨胀了碳纳米管膜的内部空间,能够显著提高其双电层电容,有利于进一步的赝电容活性物质沉积以用于赝电容电容器电极材料。(3)预膨胀后的碳纳米管薄膜可以实现多种电化学活性物质的有效负载,二氧化锰负载量高达90wt%,用于柔性对称电容器组装,获得的电容器面电容高达322 mF/cm~2。
With the concept of the flexible and wearable electronics arising, the requirement of flexible energy storage devices is enhanced. Carbon nanotube(CNT) film synthesized by floating catalyzed chemical vapor deposition has many electrochemical and mechanical characteristics, therefore it is considered as the ideal electrode material of flexible energy storage device. In this manuscript, the controllable production of CNT film, efficient functionalization of CNT film and the fabrication of flexible supercapacitor were discussed.(1) The diameter and aggregation state of CNT can be varied by controlling the growth factor.(2) Electrochemically anodic oxidization process was applied in order to functionalize the film and improve its hydrophlicity. The process was also benefit to improve the double-layer capacitance of CNT film and load the pseudocapacitor electrode materials.(3) The specific capacitance of the flexible symmetry supercapacitor based on CNT/MnO_2 film with the 90wt% loading of MnO_2 was as high as 322mF/cm~2.
