The Strain Sensing and thermal–mechanical behavior of flexible multi-walled carbon nanotube/polystyrene composite films
Carbon, 2011Co-Authors: Rajesh Kumar Srivastava, Venkata S.m. Vemuru, Satish Nagarajaiah, Pulickel Madhavapanicker Ajayan, You Zeng, Robert Vajtai, Anchal SrivastavaAbstract:Abstract The Strain Sensing and thermal–mechanical behaviors of well dispersed multi-walled carbon nanotube/polystyrene (MWCNT/PS) composite films with different wt.% of carbon nanotubes were analyzed. The thermal–mechanical properties are studied using a dynamical mechanical analyzer and the results give their storage modulus (E′) and loss modulus (E″) as a function of temperature. We found an increase in E′ of up to 122% at 80 °C for a 6 wt.% MWCNT/PS composite compared to PS. The glass transition temperature increased significantly with an increase in MWCNTs concentration. The Strain Sensing behavior of the films is measured by applying an axial load over film which is attached to a brass specimen. The composite films exhibit excellent Strain Sensing behavior for different MWCNT contents. The result shows that an electromechanical response of the composite films varies linearly with applied Strain even at high Strains.

Flexural Strain Sensing using carbon nanotube film
Sensor Review, 2004Co-Authors: Prasad Dharap, Li Zhiling, Satish Nagarajaiah, Zhiling Li, Enrique V. BarreraAbstract:Strain Sensing characteristic of carbon nanotubes has been established in the past at nanoscale. In this study, it is shown that the carbon nanotube film sensors, made up of randomly oriented carbon nanotubes, can be used as Strain sensors at macro level. A nearly linear trend between the change in voltage, measured using a movable four point probe, and Strains, measured using conventional electrical Strain gage, indicates the potential of such carbon nanotube films for measuring flexural Strains at macro level. Isotropic Strain Sensing capability of the carbon nanotube film sensors, due to randomly oriented carbon nanotubes, allows multidirectional and multi-location measurements

Nanotube film based on single-wall carbon nanotubes for Strain Sensing
Nanotechnology, 2004Co-Authors: Prasad Dharap, Satish Nagarajaiah, Zhiling Li, Enrique V. BarreraAbstract:Carbon nanotubes change their electronic properties when subjected to Strains. In this study, the Strain Sensing characteristic of carbon nanotubes is used to develop a carbon nanotube film sensor that can be used for Strain Sensing on the macro scale. The carbon nanotube film is isotropic due to randomly oriented bundles of single-wall carbon nanotubes (SWCNTs). Using experimental results it is shown that there is a nearly linear change in voltage across the film when it is subjected to tensile and compressive stresses. The change in voltage is measured by a movable four-point probe in contact with the film. Multidirectional and multiple location Strains can be measured by the isotropic carbon nanotube film.
