Carbon Nanotube Yarns

Carbon nanotube yarns (CNTYs) possess low density, high conductivity, high strength, and moderate flexibility. These intrinsic properties allow them to be a preferred choice for use as conductive elements in high-performance composites. To fully exploit their potential as conductive reinforcing elements, further improvement in their electrical conductivity is needed. This study demonstrates that tensile cyclic loading under ambient conditions improves the electrical conductivity of two types of CNTYs. The results showed that the electrical resistance of untreated CNTYs was reduced by 80% using cyclic loading, reaching the resistance value of the drawn acid-treated CNTYs. Scanning electron microscopy showed that cyclic loading caused orientation and compaction of the CNT bundles that make up the CNTYs, resulting in significantly improved electrical conductivity of the CNTYs. Furthermore, the elastic modulus was increased by 20% while preserving the tensile strength. This approach has the potential to replace the environmentally unfriendly acid treatment currently used to enhance the conductivity of CNTYs.

Abstract Aquaternized hemicellulose (QH)/chitosan/reduced graphene oxide (rGO) composite film with good mechanical propertyand electrical conductivity was prepared bysolution-casting method. The effects of reduced graphene oxide contents on the structures and properties of the composite films were investigated.The mechanical property and electrical conductivity of the film with rGO containing 0.5 wt.% was reached 102.09 MPa and 12.8 × 10− 2 S/cm, respectively.Under the functions of hydrogen bonds and Van Der Waals forces, three components were combined to obtain QH/CS/rGO composite films with higher thermal stability and conductivity. Due to the compositing of rGO, the composite films showed good UV-blocking properties.This work provided a low-cost and sustainable pathway for the application of high-strength hemicellulose composite films with electrical conductivity and UV resistance in flexible electrode materials.
