Electrospun Polymer Fibers for Electronic Applications

Abstract

Nano- and micro- fibers of conjugated polymer semiconductors are particularly interesting both for applications and for fundamental research. They allow an investigation into how electronic properties are influenced by size confinement and chain orientation within microstructures that are not readily accessible within thin films. Moreover, they open the way to many applications in organic electronics, optoelectronics and sensing. Electro-spinning, the technique subject of this review, is a simple method to effectively form and control conjugated polymer fibers. We provide the basics of the technique and its recent advancements for the formation of highly conducting and high mobility polymer fibers towards their adoption in electronic applications.

Electrospinning of Polylactic Acid/silver nanowire biocomposites: Antibacterial and electrical resistivity studies

“…Figure a and b show FESEM images of PLA/AgNWs nanofiber with 5 and 3 (wt.%) of AgNWs with higher magnification. Figure a and b depicts the structure and uniform arrangement of the nanofiber composite as a result of the influence of rotary collectors and other conditions selected in this study, consistent with the results of other researchers . As a result of the formation of PLA/AgNWs composite nanofibers, the core‐shell structure of nanofibers is expected to be developed in the polymer matrix, which is shown by TEM image in Fig.…”

“…Through a pivotal flow directed by voltage in front of a spine jet, AgNWs in presence of a PLA solution form a core‐shell structure. Test conditions including collector speed, voltage¸ flow exit rate, viscosity, and needle to collector distance influence the morphology, diameter, and orientation of nanofibers . Therefore, in this study, the optimal conditions for electrospinning were employed to produce PLA/AgNWs composite nanofibers.…”

“…The high surface area of AgNWs together with PLA nanofibers creates a high common denominator and interface. Free electrons on the interface between polymer chains and AgNWs surface move freely and easily . The high electrical potential of AgNWs make them suitable for use in many polymers where conductivity is required.…”

“…In developing conductive polymers, existing studies have focused on intrinsically conductive polymers such as poly aniline and other semi conductive polymers . Other researchers have addressed the use of nanofillers such as gold, silver, and copper nanoparticles and nanowires in some polymers to produce suitable conductive composites .…”

Fabrication and Characterization of Conductive Conjugated Polymer‐Coated Antheraea mylitta Silk Fibroin Fibers for Biomedical Applications

“…Conductive polymers appear as interesting materials for the coating of biomaterials and electrochemical or electromechanical interfacing. However, to date, few successful strategies have allowed the coating of naturally occurring fibers with conjugated polymers . As the modification of conducting polymers continues to diversify their properties, the interaction of a broader range of cell types with conducting polymers will be investigated …”
