Creating superior electrical properties from macroscopic assembly of carbon nanotubes (CNTs) to replace metal is still an unaccomplished goal. Here we report a noncovalent functionalization method to connect individual CNTs with electrical conductivity reaching 9150 S/cm and the mechanical properties can be increased by an order of 1–2.

 

創建優良的導電性能，從宏觀的角度將奈米碳管組裝成厚度為數十微米的薄膜，以取代金屬材料仍然是一個尚未達成的目標。在這裡，我們利用非共價鍵結的化學修飾方法來連接奈米碳管薄膜中各奈米碳管，經由化學修飾的奈米碳管薄膜之導電性可高達9150 S / cm〈銅的導電性：600000 S/cm〉，而其機械性能比未修飾的奈米碳管薄膜還高出10-20倍。
