The effect of applying compression and heat during the fabrication of CNT/PDMS nanocomposite on its electrical and mechanical properties. (a) The sheet resistance and (b) the conductivity of CNT/PDMS/25, CNT/PDMS/25P, CNT/PDMS/80P, and CNT/PDMS/120P samples; inset photos of b show the brightness of an LED light connected in series to nanocomposite samples. (c) The changes in the resistance of CNT/PDMS/25, CNT/PDMS/25P, and CNT/PDMS/80P samples versus tensile strain. (d) The stress–strain curves of PDMS, CNT/PDMS/25, CNT/PDMS/25P, and CNT/PDMS/80P nanocomposites. (e) The Young’s modulus of PDMS, CNT/PDMS/25, CNT/PDMS/25P, and CNT/PDMS/80P nanocomposites. (f) Illustration of the changes induced in the network of CNTs in nanocomposites due to applying tensile strain to them.
