Extended Data Fig. 5: Tensile stress results on d-/h-DPP-2T and d-/h-DPP-g2T films.
From: Highly stretchable organic electrochemical transistors with strain-resistant performance

SEM images of d-DPP-2T films with (a) 0% and (b) 30% strain; h-DPP-2T films with (c) 0% and (d) 60% strain; d-DPP-g2T films with (e) 0% and (f) 60% strain; h-DPP-g2T films with (g) 0% and (h) 60% strain (The red square stands out the cracks).
