摘要: A hollow thorn-like polypyrrole (PPy) microtube structure (HTPMT) has been prepared by in situ chemical oxidation polymerization using Methyl Orange (MO) and sodium dodecylbenzene sulfonate (SDBS) as double soft templates, which the MO SDBS performed both surfactant dopant. The hierarchical of HTPMT formed presence was different from that microtubes (PMT) or nanoparticles (PNP) separately. Scanning electron microscopy (SEM) transmission (TEM) images showed morphology had appearance thorns growing on surface PMT. TEM solutions revealed PPy polymerized end-closed tubes vesicular micelles. Electrostatic attraction between anionic micelles cationic pyrrole radicals during assisted formation HTPMT. exhibited improved electrochemical performance thermal stability compared with PMT PNP, illustrating conductive polymer influenced electrode materials.
