Especially, we report that periodic ordered mesostructures of hydrophil
7、ic ultrathin nanowires can be produced by Langmuir-Blodgett technique. The mesostructures of ultrathin Te nanowire films show reversibly switched photoelectric properties. In addition, a series of layered double hydroxides (LDH) micro/nano-platelets reinforced free-standing, strong, transparent, and
8、 functional layered organic-inorganic hybrid films can be fabricated based on layer-by-layer (LBL) assembly technique using series of LDH micro/nano-platelets as building blocks. These assembled structures based on bio-inspired approaches will find potential applications in different fields.Figure 1
