Observation of persistent photoconductivity in conducting polyaniline thin films

Controlling the photoconductivity: Graphene oxide and polyaniline self assembled intercalation

“…23 Interestingly, PANI UV-Vis has shown -PR for which two different attributions are noticed. 35,36 (1) LEB regions trap the photogenerated charge carriers under green illumination. 35 This attribution is corroborated by the fact that LEB is transparent to green light where the e/h pairs are created in ES within the interface of LEB.…”

“…35,36 (1) LEB regions trap the photogenerated charge carriers under green illumination. 35 This attribution is corroborated by the fact that LEB is transparent to green light where the e/h pairs are created in ES within the interface of LEB. Also the existence of equal amounts of LEB and pernigraniline base is suggested.…”

“…Also the existence of equal amounts of LEB and pernigraniline base is suggested. 35 (2) ES is already in the polaronic state, further photo-oxidation can form pernigranil salt which is not a good conductor. 36 The suitability of these interpretations is addressed latter.…”

Thermal behavior and matrix-assisted pulsed laser evaporation deposition of functional polymeric materials thin films with potential use in optoelectronics

“…Although the compound itself was discovered over 150 years ago [37], only since the early 1980s it has truly captured the attention of the scientific community due to its significant electrical conductivity. Amongst the family of conducting polymers and organic semiconductors, polyaniline has many appealing processing properties, being one of the most studied conducting polymers of the past 50 years: in bulk, as thin films, or as nanostructures [13,19,[38][39][40][41][42][43][44][45][46]. PAni exhibits significant absorbance in the microwave range, and it is also frequently used in gas sensors because of its capability to convert chemical interactions into electrical signals [13,19,39].…”

Preparation and characterization of transparent PANI‐SIO2 hybrid conducting films

“…Conducting polymer is also a kind of important conducting material and among various conducting polymers such as polyaniline, polypyrrole and polythiophene [5][6][7], polyaniline (PANI) has attained significant attraction for its promising chemical, electrical and optical properties, as well as its unique redox tunability [8][9][10]. On the other hand, organic solvents such as chloroform, xylene and m-cresol are necessary for solution processing of polyaniline and among these organic solvents, m-cresol can also play as a secondary dopant for polyaniline and extend conformation [11].…”
