Structure characterization of the PBONF-reinforced CNT/PVA bilayer actuators. (a) SEM image of PBONFs. (b) Photograph of a PBONF-reinforced CNT/PVA bilayer film with the diameter of ca. 4 cm. (c) Cross-sectional SEM image of the bilayer actuator. (d) Top-view and (e) cross-sectional SEM images of the PBONF-reinforced CNT layer. Red arrows mark PBONFs distributed in the CNT network. (f) Tensile stress-strain curve of the PBONF-reinforced CNT/PVA bilayer actuator at the RH of 32%.
