“…Both samples were prepared in the viscous electrolyte solutions and is expected that the PEG content to be highest on the surface of these samples. In a previous study it was concluded that molecules sequestered within the PEG-doped composites are less responsive to O 2 indicating that they are rendered inaccessible to O 2 as a result of the PEG doping [33]. This can be an explanation that the presence of PEG on the surface of Ti/PEG 600 3%w and Ti/PEG 1000 can leads to reduced corrosion rate due to the influence of cathodic reaction.…”

“…23 As shown in Fig. 25,26 However, the N1s peak could be resolved into the three constituents of HTPMT in Fig. The intensity of the exothermic peak of PMT was clearly stronger than that of HTPMT, indicating that the PPy chain in PMT had decomposed rapidly.…”

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, in which the MO and SDBS performed both as surfactant and dopant. The hierarchical structure of HTPMT formed in the presence of MO and SDBS was different from that of polypyrrole microtubes (PMT) or nanoparticles (PNP) using MO and SDBS separately. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images showed that the morphology of the HTPMT had the appearance of thorns growing on the surface of the PMT. The TEM images of the MO and SDBS solutions revealed that PPy had polymerized on the surface of the end-closed MO tubes and in the vesicular SDBS micelles. Electrostatic attraction between the anionic SDBS micelles and cationic pyrrole radicals during the polymerization assisted the formation of the HTPMT. The HTPMT exhibited improved electrochemical performance and thermal stability compared with PMT or PNP,illustrating that the morphology and structure of the conductive polymer influenced the electrochemical performance of the electrode materials. Fig. 6 The electrochemical performance of the samples: (a) CV curves at a scan rate of 5 mV s À1 , (b) GCD curves at a current density of 0.2 A g À1 , (c) the specific capacitances at different current densities, and (d) Nyquist plots.This journal is
