摘要: Abstract Intercalated polyaniline (PANI) nanosheets, supported by sodium dodecyl sulfate (SDS), have been prepared in one step from discotic nematic lyotropic liquid crystal (LLC) solutions. The inter-lamellar distance was observed to be dependent strongly on the stirring situation during polymerization: an average of 3.4 nm is favorable for samples with and without preparation, while a shorter 1.4 nm preferable when system stirred only period addition ammonium persulfate (APS). Interestingly, all UV–vis, XPS, TGA elemental analysis experiments demonstrate clearly that PANIs this way were partially doped states, although these reactions carried out at non-acidic conditions. Such phenomenon can attributed doping process induced sulfuric acid, which produced situ polymerization. Furthermore, our exhibit high specific capacitance compared other chemically systems. In particularly, superior retention propriety (as as 86.7% current density 0.4–4.0 A g −1 ) available PANI time, indicating its great potential provide power density. short, indicate intercalated nanosheet structure molecular scale benefit improving supercapacitive performance corresponding electrode material supercapacitors.
