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

SDBS-assisted preparation of novel polyaniline planar-structure: Morphology, mechanism and hydrophobicity

“…In recent years, more and more studies have been endeavored to explore micro/nanostructures of PANI because of their unusual properties and potential applications [4][5][6]. Up to the present, various approaches, such as surfactant-assisted synthesis [7], electrochemical method [8], interfacial polymerization [9], ''seed'' polymerization [10], soft template [11] and template-free method [12], have been used for the fabrication of PANI with different micro/nanostructures. A variety of PANI micro/nanostructures from zero to three-dimension (nanoparticles [13], nanorods [14], nanowires [15], nanotubes [12], micro-box [16] and microspheres [17]) have been successfully prepared by the means mentioned above.…”

Graphene oxide‐wrapped polyaniline nanorods for supercapacitor applications

“…The peaks observed at 1,720, 1,624, and 1,043 cm −1 correspond to C=O stretching, unoxidized sp 2 C‐C bonds, skeletal C‐O stretching respectively, confirming the oxidation of GO sheet . For PANI, the absorption peaks are observed at 1,546, 1,465, 1,286, and 1,230 cm −1 corresponding to the C=C quinoid, C=C benzenoid, C‐N stretching mode of the aromatic amine, C‐N‐C stretching vibration in the polaron structure , respectively as shown in Fig…”

“…Figure shows the FESEM images of GO, PANI, PANI/GO 1 , PANI/GO 5 , and PANI/GO 10 nanocomposites. Figure a shows that the GO exhibited wrinkled sheet like morphology with 50‐nm thickness and lateral size up to several micrometers , whereas the disordered crumbly and non‐spherical structures of PANI can be observed in Fig. b.…”

“…Thus, the synergistic combination of long cycling life, high rate capability of GO with high pseudocapacitance of 1D PANI nanorod will make its nanocomposites most suitable material for supercapacitor applications. Thus, various PANI nanorod modified nanocomposites viz; Graphene‐PANI nanorod array , PANI nanorods with assistance of ethylene glycol , PANI sunflower with arrays of oriented nanorods , PANI nanorod using camphor sulfonic acid , electro polymerized nanorod , supercapacitors based on GO‐doped PANI and multilayer of PANI and GO had been successfully synthesized. However, to the best of our knowledge, GO‐wrapped PANI nanorods for supercapacitor applications have not been reported.…”

Electro-synthesis and characterization of polyaniline nanofibers

“…According to literature, PANI nanostructures could be prepared using the emulsion polymerization [4,5], solution polymerization [6,7] surfactant-assisted synthesis [8], electrochemical method [9], interfacial polymerization [10], seed polymerization [11], template or template-free method [12,13] and electro-synthesis [14,15]. Among these methods, the electro-synthesis showed advantages in simple preparation procedure, accurate control of the initiation and termination steps, and formed purer PANI than that from chemical methods due to the absence of additional species [16].…”
