“…In this manuscript we detail the facile in situ synthesis of nanocomposites containing PANI nanofibers decorated with silver nanoparticles. This approach extends our previous work, where we illustrated that the PANI nanofibers could be formed using soft template of sodium alginate 33. The presence of water‐soluble metal salt in the parent solution does not alter the nanofibrillar morphology and favors the synthesis of metal nanoparticles that garnish the PANI nanofibers.…”

Polyaniline (PANI)-Ag nanocomposites were synthesized by in situ chemical polymerization approach using ammonium persulfate and silver nitrate as oxidant. Characterizations of nanocomposites were done by ultraviolet-visible (UV-vis), Fourier transform infrared (FTIR), X-ray diffraction (XRD), scanning electron microscopy, and transmission electron microscopy (TEM). UV-vis, XRD and FTIR analysis established the formation of PANI/Ag nanocomposites and face-centered-cubic phase of silver. PANInanofibers were of average diameter $ 30 nm and several micrometers in length. Morphological analysis showed that the spherical-shaped silver nanoparticles decorate the surface of PANI nanofibers. Silver nanoparticles of average diameter $ 5-10 nm were observed on the TEM images for the PANI-Ag nanocomposites. Such type of PANI-Ag nanocomposites can be used as bistable switches as well as memory devices.

Polyaniline (PANI) nanofibers have enhanced water processibility and improved sensitivity and response time when exposed to chemical vapors, and unique advantages in other fields including electric devices and corrosion inhibition. Therefore, PANI nanofibers have attracted great interest and have potential for many commercial applications. In this paper, the advantages, formation mechanism, characteristics and factors influencing various methods for preparing PANI nanofibers are described in detail. Their conductive properties and mechanism are briefly introduced. Finally, the potential applications of PANI nanofibers are elaborated in many fields such as gas sensors, capacitors, electrode materials for cells, removal of contaminants from water, corrosion inhibition, enzyme immobilization, Schottky diodes, and so on. © 2018 Society of Chemical Industry

Abstract:The fabrication of photonic and electronic structures and devices has directed the manufacturing industry for the last 50 years. Currently, the majority of small-scale photonic devices are created by traditional microfabrication techniques that create features by processes such as lithography and electron or ion beam direct writing. Microfabrication techniques are often expensive and slow. In contrast, the use of electrospinning (ES) in the fabrication of microand nano-scale devices for the manipulation of photons and electrons provides a relatively simple and economic viable alternative. ES involves the delivery of a polymer solution to a capillary held at a high voltage relative to the fiber deposition surface. Electrostatic force developed between the collection plate and the polymer promotes fiber deposition onto the collection plate. Issues with ES fabrication exist primarily due to an instability region that exists between the capillary and collection plate and is characterized by chaotic motion of the depositing polymer fiber. Material limitations to ES also exist; not all polymers of interest are amenable to the ES process due to process dependencies on molecular weight and chain entanglement or incompatibility with other polymers and overall process compatibility. Passive and active electronic and photonic fibers fabricated through the ES have great potential for use in light generation and collection in optical and electronic structures/ devices. ES produces fiber devices that can be combined with inorganic, metallic, biological, or organic materials for novel device design. Synergistic material selection and postprocessing techniques are also utilized for broad-ranging applications of organic nanofibers that span from biological to electronic, photovoltaic, or photonic. As the ability to electrospin optically and/or electronically active materials in a controlled manner continues to improve, the complexity and diversity of devices fabricated from this process can be expected to grow rapidly and provide an alternative to traditional resource-intensive fabrication techniques.
