Synthesis and Characterization of Polyindole/Poly(vinyl acetate) Conducting Composites

Novel synthesis and DC electrical studies of polyindole/poly(vinyl acetate) composite films

“…The peak at 2965 cm −1 ascribed to C H stretch of indole. The peaks at 1285, 1398, 1768, 2965 cm −1 are four characteristics peaks of PVAc [23][24][25][26][27][28].…”

Electro-optical properties of one pot synthesized polyindole in the presence of poly(vinyl acetate)

“…The peak at 1772 cm −1 also shows C=O vibrations. [13] The peak at 1396 cm −1 indicates the presence of a C=N stretch. The peaks at 1133 and 1456 cm −1 can be attributed to an aromatic C-N stretch.…”

Synthesis and electrochemical investigation of polyindole based fiber as sensor electrode by EIS method

“…Polyindole was synthesized chemically using FeCl 3 as an oxidant [16]. The molar ratio of oxidant to monomer was taken as equal.…”

“…PIN is one of the many electroactive polymers, which can be obtained by anodic oxidation of indole in various electrolytes [15]. Because of the structural resemblances of indole to pyrrole most of the structure and polymerization mechanism for PIN have been taken from polypyrrole studies [16][17][18][19][20][21]. Although, PIN films have mainly been synthesized through electrochemical oxidation [22], chemical oxidation of indole monomer by the direct chemical oxidation in the presence of FeCl 3 , CuCl 2 or (NH 4 ) 2 S 2 O 8 [23,24] has also been reported.…”
