In situ doping polymerization of polyaniline microtubules in the presence of ?-naphthalenesulfonic acid

Synthesis, characterization and properties of polyaniline/expanded vermiculite intercalated nanocomposite

“…The absorption peak at 1557 cm −1 is attributed to the quinoid ring stretching, 1480 cm −1 is for the benzene ring stretching, 1300 and 1243 cm −1 are for the N-H stretching in the connecting benzene ring-quinoid ring and benzene ring-benzene ring, respectively, and 1124 and 814 cm −1 are asymmetric peak stretchings of SO 3 − . There are two absorption peaks at 1020 and 664 cm −1 , which is consistent with the results given in a previous report [11]. Owing to the doping of SDBS into the PANI, a -CH 2 -absorption at 2992 cm −1 is observed.…”

Electrical Conductivity Studies of Polyaniline Nanotubes Doped with Different Sulfonic Acids

“…Many techniques have been used to synthesize PANI nanostructure such as stirring [6][7][8], static placement, [9] sonication [10][11][12], and emulsion polymerization [13][14][15][16]. Particularly, conducting polymer nanotubes and nanofibers have received growing interest in recent years due to their unique properties and promising potential applications in nanodevices [17][18][19][20][21]. The investigation of nanostructured conducting polymers has great importance for both scientific and technological points of view.…”

Synthesis of rectangular tubes of polyaniline/NiO composites

“…[5][6][7][8][9][10] Recently, the morphology of PANI has aroused considerable interest and has been widely studied for its influence on physical properties. Zeolite, 5 porous alumina, 11 and polymer fibers 12 have been used as hard templates to synthesize PANI nanotubes and nanofibers.…”
