Fig. 2

a An optical microscopy image of the NCC membrane located on a 300 nm SiO2/Si wafer. b The membrane thickness profile of 6.2 ± 0.5 nm determined by AFM. c The roughness of the NCC membrane with 1.56 ± 0.53 nm. d The POM image of the NCC membrane showing the birefringence pattern. e Two-dimensional GI-WAXS patterns of the nanofilm that was transferred on a silicon wafer. The most prominent Bragg reflection (110) was found. f HRTEM image and SAED pattern (inset) of the nanofilm. Error bars represent the standard deviation from three duplicate experiments.
