Conducting polyaniline composite: From syntheses in waterborne systems to chemical sensor devices

Ammonia/amine electronic gas sensors based on hybrid polyaniline–TiO2 nanocomposites. The effects of titania and the surface active doping acid

“…[22][23][24][25] In this regard, one of the most prominent ICPs is polyaniline (PANI) due to its ability to participate in typical acid-base interactions. [26][27][28] In particular, contact of acids doped PANI with basic substances leads to its dedoping by deprotonation and can be used for ammonia/amines concentrations determination (Fig. 1).…”

Biocompatibility evaluation of aniline oligomers with different end-functional groups

“…[1][2][3][4][5][6] Because of its excellent electrical and optical properties, PA and PA based materials have been investigated for various applications including electronic nanodevices, catalysis and electrocatalysis, antifouling coatings, microwave absorption, electromagnetic interference shielding, electrorheological fluids, chemical and biological sensors, radical scavengers and antimicrobials, etc. [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] In particular, the biomedical applications of PA and other CPs, such as tissue engineering and neural probes, have recently attracted more and more attention, because cell activities such as cell adhesion, cell differentiation and cell growth could be tuned by electrical stimulus. [25][26][27][28][29][30][31] However, the main challenges in biomedical applications of PA and other CPs lie in their insolubility and non-degradability, which may induce adverse effects for long term in vivo applications.…”

Engineering of Calcium Alginate- PANI@Sawdust Wood hydrogel Bio-beads for the Removal of the Sulfonate Groups-Containing Orange G dye from Aqueous Solution

“…The FTIR spectrum of PANI@SD biocomposite depicts peaks at 1595 cm −1 and 1493 cm −1 ascribing to the typical C=C stretching of quinoid and benzenoid rings, respectively. The occurrence of these two bands indicates the synthesis of PANI and the presence of its amine and imine groups (Joubert et al 2010). The band at 1306 cm −1 corresponds to the N-H bending mode.…”
