a Schematic of an autonomous self-healing semiconducting film, featuring the chemical structure of a self-healing elastomer (PDMS–MPU0.6–IU0.4) and a semiconducting polymer (DPPT-TT). b AFM analysis of the 3:7 (DPPT-TT: SHE) blend ratio film: (i) height, (ii) phase, (iii) DMT modulus, and (iv) C-AFM images. c Elastic modulus and onset strains of cracks in the films with different blend ratios of self-healing semiconductor. d Field-effect mobilities of blend films as a function of the blend weight ratio (DPPT-TT:SHE). e Field-effect mobility ratios of the blend films as a function of the blend weight ratio and tensile strain. f OM images of the 3:7 blend ratio film at 0% (left) and 100% strain (right). g Dichroic ratio from polarized UV–Vis–NIR spectra at each tensile strain. h XPS spectra of the 3:7 blend film. GIXD of the 3:7 blend film under 0% and 30% strain, where the strained film was stretched parallel and perpendicular to the beam line. i out-of-plane and (j), in-plane film direction. All error bars were calculated using a sample in each of three batches (n = 3).
