Studies on formation mechanism of polypyrrole microtubule synthesized by template‐free method

Tuning nano-architectures and improving bioactivity of conducting polypyrrole coating on bone implants by incorporating bone-borne small molecules

“…3a could be assigned to the repeating unit with a periodic distance of d ¼ 5.9 Å between PPy chains, which could be calculated by Bragg's equation. Our data showed that the citric acid concentration reaching a specic level allowed the alignment of PPy chains, which was different from the reported amorphous (or partially crystalline) micro/ nano-architectured [44][45][46] and 1D NAPPy/NSA (Fig. 2e4 and Fig.…”

Enhanced capacitance of rectangular-sectioned polypyrrole microtubes as the electrode material for supercapacitors

“…Additionally, it is believed that the bands at 1302, 1168 and 1039 cm À1 are ascribed to on-plane vibration of ]C-H, and the band at 893 cm À1 is for ]C-H out-of-plane vibration, respectively. [29][30][31] This indicated that the backbone of the PPy prepared in the KI-I 2 and b-CD system is the same as that of PPy prepared by conventional route.…”

Polyaniline/TiO2 Composite Nanotubes

“…On the basis of our previous studies, − the micelles formed by β-NSA anions and anilinium cations might act as templates in the formation of the self-assembled PANI nanotubes of conducting polymers. Generally speaking, β-NSA easily forms micelles in aqueous solution due to its hydrophobic (naphthalene ring) and hydrophilic (−SO 3 H) groups.…”
