Preparation of TiO2/PANI composites in the presence of surfactants and investigation of electrical properties

Preparation and characterization of conductive chitosan-poly[N-(3-trimethoxysilylpropyl)aniline] hybrid submicrostructures

“…The band at 571-639 nm shows π-π* tran- sitions within the quinoid structure. 38 The wavelength of the quinoid band plays an important role in switching polyaniline and its derivatives from an electric insulator to a conductor upon doping. The same significant bands are observed for the CS-PTMSPA spheres (Figure 2(c)) and fibers (Figure 2(d)).…”

Preparation of polyaniline–TiO2 nanotube composite for the development of electrochemical biosensors

“…In trace c, both the absorption band corresponding to Ti O Ti vibration (below 1000 cm −1 ) and the characteristic bands of PANI (between 700 and 1600 cm −1 ) can be observed, indicating the formation of PANI-TNT composite. However, these characteristic bands of PANI have shifted to higher wavenumbers due to the strong interaction between the oxygen atoms on TNTs and the protons on PANI [26]. Specifically, the peaks at 1565, 1473, 1297 and 1126 cm −1 , corresponding to the stretching mode of C C, C N and N Q N bands of PANI have shifted to 1579, 1495, 1311 and 1153 cm −1 , respectively.…”

PANI/NaTaO3 composite photocatalyst for enhanced hydrogen generation under UV light irradiation

“…The spectrum of PANI shows two strong peaks. The peak at about 320 nm is assigned to the π-π * transition of benzene rings and the peak at about 630 nm is attributed to the transition of the quinoid rings in long PANI chains 20 . For pure NaTaO 3 a single absorption edge at around 300 nm, indicating the band gap energy of 4.11eV carriers separation and transfer in semiconductors 26- 28 and to understand why the introduction of PANI leads to the enhance the photoactivity of NaTaO 3 .…”
