(a) Three-dimensional AFM appearance of thermite membrane surfaces.The inset shows typical water contact angle measurements of the silicone-coated thermite membrane. (b) Stress-strain curves for pristine thermite membrane and silicone-coated thermite membrane made based on the S2 composition. (c–e) Photographs of the silicone-coated thermite membrane immersed in water remain unaltered its wetting behavior.
