General synthesis of two-dimensional patterned conducting polymer-nanobowl sheet via chemical polymerization

A general method for the generation of two-dimensional (2D) ordered, large-area, and liftable conducting polymer-nanobowl sheet has been demonstrated via chemical polymerization for the first time. The sheet is made using the monolayer self-assembled from polystyrene (PS) spheres at the aqueous/air interface as template, followed by depositing conducting polymer on the part of PS monolayer submerging in the aqueous phase via chemical polymerization, and core extraction. During the process of polymerization, no substrate is required, which caused the as-prepared patterned conducting polymer sheet can be easily lifted-off and deposited, in full size, on any flat substrate. Scanning electron microscopy (SEM), transmission electron microscopy (TEM), and Fourier transform infrared (FTIR) spectrum were used to characterize the products
