“…Figure 3 a–e shows the photograph images of pure MC (image a), MC/1%PANI (image b), and MC/3%PANI (image c) films. As can be seen, the color of the MC film gradually changed from white to light green, and then dark green after the addition of 1 wt% and 3 wt% of PANI, respectively [ 18 ].…”

In order to potentiate implementations in optical energy applications, flexible polymer composite films comprising methyl cellulose (MC), polyaniline (PANI) and silver nanoparticles (AgNPs) were successfully fabricated through a cast preparation method. The composite structure of the fabricated film was confirmed by X-ray diffraction and infrared spectroscopy, indicating a successful incorporation of AgNPs into the MC/PANI blend. The scanning electron microscope (SEM) images have indicated a homogenous loading and dispersion of AgNPs into the MC/PANI blend. The optical parameters such as band gap (Eg), absorption edge (Ed), number of carbon cluster (N) and Urbach energy (Eu) of pure MC polymer, MC/PANI blend and MC/PANI/Ag films were determined using the UV optical absorbance. The effects of AgNPs and PANI on MC polymer linear optical (LO) and nonlinear optical (NLO) parameters including reflection extinction coefficient, refractive index, dielectric constant, nonlinear refractive index, and nonlinear susceptibility are studied. The results showed a decrease in the band gap of MC/PANI/AgNPs compared to the pure MC film. Meanwhile, the estimated carbon cluster number enhanced with the incorporation of the AgNPs. The inclusion of AgNPs and PANI has enhanced the optical properties of the MC polymer, providing a new composite suitable for energy conversion systems, solar cells, biosensors, and nonlinear optical applications.

“…Through observing SEM images of PANI-Ag (Figure 1), it was noticed that the composites' surface morphology differed from what was reported in literature. Compared with other PANI-Ag composites, such as tubular nanorod structure, [17] core-shell structure and the fiber block structure, [18,19] the surface morphology of PANI-Ag composites synthesized by us presented intercalated nanoflower like structure when the glucose concentration was 0.0278 mol/L (Figure 1C). It reflected that the glucose concentration was relatively suitable at this time.…”

In this article, an environmentally friendly and simple one-pot synthesis method to prepare polyaniline-silver composite materials is presented by using glucose as the reducing agent. The structure and morphology of the composites are confirmed and characterized by UV-visible spectroscopy, Fourier transform-infrared spectroscopy, X-ray diffraction, thermogravimetric analysis, and scanning electron microscopy (SEM). Based on the SEM micrographs, the polyaniline-silver composites with typical morphology of intercalated nanoflowers are synthesized for the first time. In addition, the electrical conductivity, oxidation resistance, and antibacterial property of the composites are enhanced compared with those of polyaniline. This study is expected to provide insights and opportunities for improving the preparation methods and conditions of polyaniline-silver composites.

“…In this regard, noble metals are preferred to others for their properties. By this approach PANI composites with Au [114,115], Ag [116,117], Pt [118,119], Cu [74,120], etc. were prepared.…”

: Conducting polymers are an outstanding class of materials characterized by electroconducting properties that make them good candidates for applications in several sectors. Among them, polyaniline (PANI) is unique for its extraordinary ability to conduct electricity, biocompatibility and low toxicity. In spite of its surprising features, to date PANI have not yet found application in the practical uses, because of its low solubility and processability. In order to overcome these limitations, different approaches have been developed, such as polymer grafting processes, PANI-based composites and blends preparation. The present review describes the most recent advances on PANI applications in biomedical fields, such as antioxidant, antimicrobial and antivirus activity, drug delivery, cancer therapy, etc. A look to the synthetic procedures is also reported because it is crucial for the realization of more innovative materials in the next future.
