We report that combining oxidised carbon nanotubes (O-CNTs) and pristine CNTs may be the answer for more electroconductive composites. Short (<1 μm) oxidised multi-wall CNTs (O-MWCNTs) acted as an unobvious and excellent conductivity enhancer in MWCNT-based composite thin films. 'Blending' O-MWCNTs (1.5 wt%) with 250 μm-long MWCNTs (98.5 wt%), both of well-defined morphology and physicochemistry, led to a 3- and 26-fold increase in specific conductivity as compared to purely MWCNT- or purely O-MWCNT-based thin films, respectively. We explain the enhanced conductivity by the effect of a dual-domain structure of O-MWCNTs. The scale-up method, screen-printing, opens a route to application in textronics ( electrical and electronic textiles) and hence targets for medicine, civil/military engineering, wellness, .
我们报道，将氧化碳纳米管（O-CNTs）与原始碳纳米管相结合可能是制备更具导电性复合材料的答案。短（<1μm）的氧化多壁碳纳米管（O-MWCNTs）在基于MWCNT的复合薄膜中作为一种不明显但出色的导电性增强剂。将具有明确形态和物理化学性质的1.5 wt%的O-MWCNTs与250μm长的MWCNTs（98.5 wt%）“混合”，与纯MWCNT基或纯O-MWCNT基薄膜相比，分别使比电导率提高了3倍和26倍。我们通过O-MWCNTs的双域结构效应来解释导电性的增强。放大方法——丝网印刷，为在电子织物（电气和电子纺织品）中的应用开辟了一条途径，因此可用于医学、民用/军事工程、健康等领域。
