The measurement of properties in carbon nanotube yarns
The paper focuses on the importance of using specific values (values where the axial property is normalised by dividing by density) for properties of CNT yarn-like fibres to avoid the huge uncertainties introduced by the state of lateral compression of the yarn, a difficulty not only associated with the measurement of cross sectional area, but exacerbated by the influence of winding forces and ...
متن کاملFrom Carbon Nanotube Yarns to Sensors: Recent Findings and Challenges
Carbon nanotube (CNT) arrays can be drawn into a web and then twisted into threads. These CNT threads contain thousands of carbon nanotubes in their cross-section and can be further composed into yarns consisting of one or more threads. CNT yarns exhibit significant mechanical stiffness and strength and low electrical resistivity. More importantly, CNT yarns exhibit piezoresistance that could b...
متن کامل2010: Structure and Process Dependent Properties of Solid-State Spun Carbon Nanotube Yarns
Introduction We have previously reported downsizing ancient twistbased spinning technology for making continuous, densified nanotube yarns from multi-walled carbon nanotube (MWNT) forests [1]. Such nanotube yarns provide unique properties and property combinations. Despite this important progress, the relationship between nanotube yarn properties and component carbon nanotube properties is not ...
متن کاملSpinning Carbon Nanotube Nanothread under a Scanning Electron Microscope
Nanothread with a diameter as small as one hundred nanometers was manufactured under a scanning electron microscope. Made directly from carbon nanotubes, and inheriting their superior electrical and mechanical properties, nanothread may be the world's smallest man-made fiber. The smallest thread that can be spun using a bench-top spinning machine is about 5 microns in diameter. Nanothread is a ...
متن کاملVertically aligned pearl-like carbon nanotube arrays for fiber spinning.
Due to their unique structure and physical properties and numerous potential applications, carbon nanotubes have been extensively studied recently and are expected to attract more attention in the future.1 Morphology control of carbon nanotubes represents one of the most explored directions. Except for the normal linear structure, nanotubes with morphologies of ring,2 rocket,2 branch,3 cone,4 b...
