Synthesis of Large‐Area Three‐Dimensional Polyaniline Nanowire Networks Using a “Soft Template”

Abstract

Summary: Three‐dimensional polyaniline (PANI) nanowire networks were synthesized in high yield using a “soft template” self‐assembled with hexadecyltrimethylammonium bromide and oxalic acid. The PANI nanowire networks had diameters from 35–100 nm depending on synthesis conditions and/or procedures. The networks and the “cross‐linking points” were clearly observed by field‐emission scanning electron microscopy and transmission electron microscopy. A possible mechanism for the formation of three‐dimensional PANI nanowire networks is discussed.

Facile synthesis of polyaniline “sunflowers” with arrays of oriented nanorods

“…In this work, the concentration of CTAB, aniline and HNO 3 , as well as the reaction temperature were systematically studied on morphologies of prepared PANI nanostructures. To the best of our knowledge, nanostructured PANI has been prepared by using a cationic surfactant as structure directing reagent and HNO 3 as dopant [12][13][14]21,40]. However, it is rarely reported to further assemble the oriented 1D PANI nanostructures into complicated ones like array in these conditions.…”

“…Up to now, 1D PANI nanostructures have been synthesized by chemical oxidative routes adopting the templates like porous solid material [8], seeding polymerization [9], structure directing reagents [10][11][12][13][14][15], oligomer assistants [16] as well as the route of self-assembling [17,18]. In particular, the PANI nanowire can be readily prepared in a stationary state, and thus considerable efforts have been paid on its forming mechanism so far [19][20][21][22][23][24][25].…”

Capacitive properties of PANI/MnO2 synthesized via simultaneous-oxidation route

“…Both PANI/MnO 2 and MnO 2 exhibit a distorted semicircle in the highfrequency region. It is attributed to the charge-transfer resistance (R ct ) from the interface structure between the electrode surface and electrolyte [37,38]. From the point intersecting with the x-axis in the range of high frequency, a very small internal resistance (R s ) can be evaluated.…”

Synthesis of dendritic polyaniline nanofibers by using soft template of sodium alginate

“…16,17 In the field of intrinsically conductive polymers, for instance, polypyrrole, polythiophene, polyaniline (PANI) etc., the PANI is unique because of its relatively facile processability, excellent environmental stability, tunable conductivity switching between insulating and semiconducting materials, easy acid/base doping/dedoping behavior, reversible redox property, 18 and low cost. Fast transfer of electrons in nanoscaled PANI, [19][20][21][22][23][24][25] having fascinating morphologies and architectures offers the possibility of improved performance.…”
