细菌纤维素@聚吡咯-单壁碳纳米管导电膜的制备与表征
|
摘要
为了获得柔性高电导率导电材料,以细菌纤维素(BC)、吡咯(Py)和单壁碳纳米管(SWCNTs)为原料,在不添加任何黏合剂的情况下,通过简单的原位氧化聚合和真空过滤法制备了BC@聚Py-SWCNTs(BC@PPySWCNTs)新型导电膜。通过SEM、FTIR对BC@PPy-SWCNTs复合膜的表面形貌、化学成分进行表征。研究了BC@PPy-SWCNTs膜的电化学性能。结果表明,在SWCNTs添加量为4.7%(质量比)时,BC@PPy-SWCNTs复合膜的电导率可达到6.42S·cm-1,相比BC@PPy有了很大提高,在充电电流为5mA·cm~(-2)时,其面积电容可达到0.53F·cm~(-2),其能量密度达0.036mWh·cm~(-2),功率密度达到1.75mW·cm~(-2)。BC@PPy-SWCNTs膜拓宽了电极材料的种类,有望应用于超级电容器、电池及传感器等领域。
In order to obtain flexible high-conductivity conductive materials,a novel conductive film of bacterial cellulose@polypyrrole-single wall carbon nanotubes(BC@PPy-SWCNTs)composite films was prepared by simple in situ oxidative polymerization and vacuum filtration using BC,pyrrole(Py)and SWCNTs as the raw materials without any adhesive.The surface morphology and chemical composition of BC@PPy-SWCNTs composite films were characterized by SEM and FTIR.The electrochemical properties of BC@PPy-SWCNTs composite films were studied.The results demonstrate that when the 4.7% mass ratio of SWCNTs is added,the conductivity of BC@PPySWCNTs film can reach 6.42 S·cm-1,which is much higher than that of BC@PPy film.When the charging current is 5 mA·cm~(-2),the area capacitance of BC@PPy-SWCNTs composite films can reach 0.53 F·cm~(-2) with an energy density of 0.036 mWh·cm~(-2) and a power density of 1.75 mW·cm~(-2),respectively.The film widens the variety of BC@PPy-SWCNTs composite films electrode composite films,which has a great possibility for use in supercapacitors,batteries,and sensors.
