摘要: Herein, the use of a 2D soft template system composed hundred-nanometer-thick water/ethanol mixed layers sandwiched by lamellar bilayer membranes self-assembled amphiphilic molecule to produce ultrathin polyprrole (PPy) with uniform thickness as thin 3.8 nm and large dimensions (>2 μm(2)) is presented. The obtained PPy nanosheets exhibit regioregularity ordered chain alignment where polymer chains in produced are well aligned clear interchain spacing confirmed small-angle X-ray scattering measurement. molecular-level-thick extremely high conductivity up 1330 S m(-1), thanks nanosheets, transparency both visible region (transmittance >99%) near-infrared >93%).
