摘要
以多壁碳纳米管为基板,运用简单磁力搅拌方法,通过π-π堆积作用,使1,4-二氨基蒽醌负载于多壁碳纳米管材料上,获得了聚氨基蒽醌/多壁碳纳米管复合物(PDAAQ/MWCNTs)。采用傅立叶红外光谱(FTIR)、透射电子显微镜(TEM)、循环伏安(CV)和恒流充放电(GCD)等方法对PDAAQ/MWCNTs的结构和性能进行表征。结果发现3~4 nm厚的聚氨基蒽醌层原位生长在多壁碳纳米管上,这种独特的结构极大地增加了复合物的比表面积和聚氨基蒽醌的利用率。分散性能好的PDAAQ/MWCNTs复合物具有高的赝容性能。
A simple magnetic stirring process to synthesize poly( diaminoanthraquinone) / multiwalled carbon nanotubes( PDAAQ / MWCNTs) composite using 1,4-diaminoanthraquinone( DAAQ)and multi-walled carbon nanotubes( MWCNTs) via π- π stacking was reported. The as-prepared composite was investigated by Fourier transform infrared spectroscopy( FTIR),transmission electron microscopy( TEM),cyclic voltammetry( CV) and galvanostatic charge-discharge( GCD). The results showed that a 3- 4 nm thickness of PDAAQ was well coated on the outer surface of the MWCNT,which clearly indicated the formation of a multilayer of DAAQ molecules on the nanotube surface.This unique structure of PDAAQ / MWCNTs composite greatly increases the surface area of composite and the utilization of PDAAQ. Thus,the homogeneous PDAAQ / MWCNTs composite exhibits a high pseudocapacitance characteristic.
