摘      要：The Assembly of one-dimensional(1D)nanostructures such as nanowires/nanorods/nanotubes into twodimensional(2D)macrostructured films is attracting considerable research interest because of their unique properties and wide *** this study,flexible membranes were successfully fabricated using a-MnO2nanowires synthesized through a hydrothermal *** effects of thickness and post-annealing temperature on the mechanical properties of the membranes were investigated in ***-indentation measurements showed that the modulus of the as-prepared 11.75 lm-thick membrane reached5.765 GPa,and the modulus increased with the increasing post-annealing ***,the fabricated membranes with superior mechanical strength can have potential applications such as in photocatalysis,filtering,and supporting substrates.
