“…The composites also exhibited this absorption peak; this was due to the presence of PPy. In case of the V 2 O 5 –MnO 2 blend, a sharp absorption was noted around 210 nm; this was related to the charge‐transfer transition involving oxygen and metal ions in tetrahedral coordination . The absorption peak due to blending was not observed in the composites; this confirmed that the blend particles were well covered by the polymer layer and was consistent with the SEM results.…”

In this study, polypyrrole (PPy) and its bimetallic oxide composites (PPy-V 2 O 5 -MnO 2 ) were synthesized via a modified chemical oxidation polymerization method in the aqueous medium with FeCl 3 Á6H 2 O as an oxidant. The synthesized materials were characterized with various analytical techniques to investigate their structural, crystallographic, thermal, morphological, optical, and electrical properties. The Fourier transform infrared study confirmed the successful synthesis of the materials, whereas the X-ray diffraction analyses showed the amorphous and crystalline natures of the PPy and PPy-V 2 O 5 -MnO 2 composites, respectively. The bimetallic oxide content improved the thermal stability of the composites, as ratified by thermal analysis. The synthesized PPy had a globular and spongy nature, whereas the composites were mixtures of short and long rod-shaped particles. The bimetallic oxide blend enhanced the doping, surface area and semiconducting nature of composites, and lower electrical resistance compared with those of the PPy. The resistance of the synthesized materials depended on the V 2 O 5 -MnO 2 blend content in the composites and the temperature.

“…More recently, the addition of nano-TiO 2 into cement-based material has won great attention due to its chemical stability, high catalytic activity and low price [23][24][25]. However, the recognition of its effects on the properties of cement-based materials was far from satisfactory.…”

“…TiO2/(TiO2-V2O5)/polypyrrole (PPy) nanocomposites were synthesized by Piewnuan et al [79] using in situ polymerization. According to the results, the absorbance of the nanocomposites was higher than those of neat TiO2 and TiO2/PPy due to the reduction in the band gap energy of the materials.…”

There has been an extensive investigation in the field of optical applications of nanocomposite materials. To prepare photosensitive nanocomposites, an optically functional phase is embedded in a transparent, processable matrix. This provides the opportunity to utilize the optical properties in other forms including fibers and films, which are more technologically important. Due to expansion of optical materials applications, novel transparent materials and optically functional are required. Recent optical nanocomposites and their applications in different areas especially catalysis and drug delivery have been addressed in this paper.
