Fig. 3

Representative AFM images of the NT2RepCT (title in black) and NT2RepY-FCT fibers (title in green) in the a, b dry state, c, d after being supercontracted at 75% relative humidity (RH), e, f after being supercontracted at 80% relative humidity. g Representative AFM topological image of the NT2RepY-FCT fibers contracted at 85% relative humidity and h NT2RepY-FCT fibers contracted at 95% relative humidity. Scale bars is 100 nm. Black color is used for NT2RepCT fibers and green color for NT2RepY-FCT fibers.
