a, b SEM image of a PWS film. c Topology AFM images of a PWS film. d 3D topographical AFM image. e, f Phase AFM images of a PWS film. g Stress-strain curves of PWS films with different PEDOT:PSS loadings. h Young’s modulus and elongation at break of PWS films with respect to the PEDOT:PSS loading. i Tensile stress–strain curves of PWS films in the first 10 cycles. The tensile speed was 50 mm/min. The PEDOT:PSS loading was 19 wt% for a–f, and i.
