a Photograph of the painted MBP hybrid film on a curved surface of stainless-steel foil. b Thicknesses of the painted MBP hybrid films as a function of the number of paintings. The average and standard deviation of the thicknesses of 14 different areas in each sample are represented as data points ± error bars. The error bars are 1.20, 1.30, 2.58, and 3.05 μm (from left to right). c Thicknesses of the films painted on stainless-steel foils (thickness ≈ 100 μm) over a large area of 25 mm × 5 mm. The inset shows an image of the painted MBP sample. d Cross-sectional SEM images of the MBP hybrid film on the various substrates including the stainless-steel foil (i and ii), glass (iii and iv), and nylon fabric membrane (v and vi). Contact angles of the bare substrates are included on the upper right in (i, iii, and v). e Photograph of the painted MBP hybrid film on the nylon membrane with a large area of 10 × 30 cm2. f Resistance changes as a function of the bending cycle of the hybrid film of painted MBP40 on a nylon membrane at different bending radii. The insets show OM images of the released and bent MBP hybrid film∕nylon membrane sample. g Magnified view of the yellow dashed area in (f).
