Carbon Nanotube Microfiber Actuators with Reduced Stress Relaxation
Abstract
International audience ; Assembling carbon nanotubes (CNTs) into robust macroscopic structures remains the main challenge to efficiently exploit their electromechanical properties in actuator applications. CNT-based actuators generally suffer from creep and stress relaxation due to poor interactions between the assembled CNTs. In order to overcome this limitation, a new class of porous single wall CNT microfiber electrodes is here proposed. The present fibers are produced by a wet spinning process and generate a mechanical stress when they are stimulated at low voltage (∼1 V) in a liquid electrolyte. The used fabrication process enables the inclusion of small amounts of chemically cross-linked polymer such as poly(vinyl alcohol) within the fibers. The presence of cross-linked polymer limits the sliding of nanotubes with respect to each other, without sacrificing the porosity and electrical conductivity of the fibers. As a result, stress relaxation is greatly reduced. The fibers generate a negative stress (propensity to expand) when a positive or negative voltage is applied.
