SECONDARY FILLERS IMPROVE THE SELF-HEALING AND ELECTROMECHANICAL PROPERTIES OF DIELS-ALDER-BASED CARBON COMPOSITES
Abstract
The addition of an organo-modified nanoclay to a carbon-based electrically conductive self-healing composite shows a synergistic improvement of both the electrical conductivity and self-healing ability of the formed hybrid composites. The effect on the electrical, viscoelastic, and self-healing properties was studied for Diels-Alder-based reversible polymer networks with a maleimide-to-furan stochiometric ratio of 0.6, with different loadings of carbon black and nanoclay Cloisite 15A. The study was performed to optimize the content of carbon black and Cloisite 15A to achieve the best combination of electrical and self-healing properties by exploiting the synergistic effect of hybrid fillers. Hybrid composites were prepared with carbon black contents up to 20 wt.% and nanoclay loading was varied between 0-1.5 wt.%. It was concluded that depending on the carbon black content, the addition of the nanoclay can improve the electrical, mechanical, and rheological properties of composites synergistically. More importantly, the presence of Cloisite 15A increased the mechanical healing efficiency of the polymer composites after healing at 90 oC for 1 hour. Besides, the influence of design parameters on the electrical conductivity and self-healing properties of polymer composite was investigated by manipulating three variables; first, changing processing technique by sonicating composites in different times and amplitudes, second, replacing secondary filler by other organo-modified nanoclay types that have different organic modifiers and interlayer spacings, and third, altering chemistry and cross-linking density of the Diels-Alder network. Finally, the electromechanical properties of the selected hybrid composites with the best combinations of two fillers were studied for sensor applications. Self-healing strain sensors show a positive piezoresistive response after a low strain region up to their failure. These promising results suggest the use of studied electrically conductive and self-healing hybrid composites for deformation and damage sensing applications in soft robotics.
