摘要

We characterize the monodomain nematic liquid crystal elastomers enriched with the carbon nanotubes (LCE-CNT composites) with the purpose of general understanding the fundamentals of their mechanical actuation behavior when illuminated by light and with the final objective to facilitate the design of photo-actuators based on LCE-CNTs. The parameters like absorption spectra and absorption coefficients of the material as a function of CNTs concentration have been studied. Temperature-induced three dimensional deformations were compared with the photo-induced deformations monitored using SEM and conventional optical microscopy techniques, combined with thermal imaging done with the IR camera.
