我们证明了单壁碳纳米管（SWCNT）类型和纳米管-基质聚合物-纳米管（CNT-P-CNT）结对SWCNT/聚合物复合材料的电光性能有深远的影响。基于CoMoCAT (R)生产的SWCNTs （SWCNTsCoMoCAT）的复合红外传感器显著优于基于HiPco (R)生产的SWCNTs （SWCNTSHiPco）的复合红外传感器。在单壁碳纳米管材料中，较高的半导体纳米管浓度对于增强红外光对单壁碳纳米管/聚合物纳米复合材料的光效应至关重要，而CNT-P-CNT结在红外光对负载型单壁碳纳米管/聚合物复合材料薄膜的热效应中起主导作用。2009爱思唯尔有限公司版权所有。
We demonstrate that both single-walled carbon nanotube (SWCNT) types and nanotube-matrix polymer-nanotube (CNT-P-CNT) junctions have profound impact on electro-optical properties of SWCNT/polymer composites. Composite IR sensors based on CoMoCAT (R)-produced SWCNTs (SWCNTsCoMoCAT) significantly outperform those based on HiPco (R)-produced SWCNTs (SWCNTSHiPco). Higher semiconducting nanotube concentration in a SWCNT material is critical to enhance the photo effect of IR light on SWCNT/polymer nanocomposites, whereas CNT-P-CNT junctions play a dominant role in the thermal effect of IR light on supported SWCNT/polymer composite films.
