Stretchable conductors based on CNT-polymer composites. a Elastic conductors comprising super-growth SWCNTs uniformly dispersed in a fluorinated rubber: Left, optical images of screen printed patterns with a feature width of 100 μm; middle, conductivity as a function of tensile strain for three samples with different SWCNT content; right, stretchability and conductivity as a function of SWCNT content. Reproduced from ref. [80]. b-d Highly conductive and stretchable hybrid composites of silver flake and MWCNTs decorated with self-assembled silver nanoparticles. b Diagram of the synthesis process. c Conductivity as a function of tensile strain. d SEM images of the nanocomposites at a strain of 50 %.
