Strengthening mechanism of electrothermal actuation in the epoxy composite with an embedded carbon nanotube nanopaper

Popis výsledku v původním jazyce

We assessed an effect of an embedded electro-conductive multiwalled carbon nanotubenanopaper in an epoxy matrix on the release of the frozen actuation force and the actuation torque inthe carbon nanotube nanopaper/epoxy composite after heating above its glass transition temperature.The presence of the nanopaper augmented the recovery of the actuation stress by the factor of twoin comparison with the pure epoxy strips. We proposed a procedure that allowed us to assessthis composite strengthening mechanism. The strengthening of the composite was attributed tothe interlocking of the carbon nanotubes with the epoxy. When reheated, the composite samples,which contained stretched mutually intertwined nanotubes and epoxy segments, released a greateractuation stress then the epoxy samples, which comprised of less elastic networks of crosslinkedsegments of pure epoxy.
