This paper determines the Young’s modulus of nanohoneycomb structures by flexural testing in an atomic force microscope (AFM). Since the cross-sectional area of nanohoneycomb structures varies along the structure, the area moment of inertia is not a constant. The area moment of inertia is also influenced by the porosity of the nanohoneycomb structure. An anodic aluminum oxide (AAO) film is fabricated as a nanohoneycomb structure. Young’s modulus of the AAO film, measured from the results of flexural testing in AFM, is in good agreement with the results of tensile tests in a Nano-UTM (universal testing machine).
