Polymers are huge compounds made up of numerous monomers (repeatedsubunits). They have similar macro and micro properties, as well aselectrical transport qualities, semiconductive capabilities, and opticalfeatures. With the advent of conductive polyacetylene, conductivepolymers have gotten a lot of interest. These conductors have a wide rangeof electrical conductivity, which may be produced by doping, while beingmechanically flexible and having a high thermal stability. Polymers may becreated using a variety of methods, including chemical and electrochemicalpolymerization. With advancement in material stability and greaterproperty control, an increasing variety of new applications are now beinginvestigated.

“…Next, the static electricity generator is turned on with a constant voltage between 19 and 21 kV that enables the electrospinning solution to overcome the surface extension and then form a jet. Afterwards, the resulting electrospun fibers are collected so as to form PVA/CNT electrospun films over the collection board [32][33][34][35][36]. The electrospun films are tested for fiber diameter analysis, surface observation, conductivity, hydrophilicity, and cell compatibility.…”

The recovery of impaired peripheral nerves is often not as expected, which makes the development of nerve conduits trendy nowadays. To enable the neural messages effectively being delivered as well as to prevent the secondary damage during the removal of nerve conduits, the conductivity and biodegradability are two essential requirements for ideal nerve conduits. In this study, electrospinning is used to produce polyvinyl alcohol (PVA)/carbon nanotubes (CNT) electrospun films, after which the morphology analysis, electrical property, water contact angle, and biological characteristics of the membranes are investigated, thereby determining the optimal nerve conduits based on the employment of electrospinning, PVA, and CNT. The test results indicate that with 0.25 wt% of PVA, the electrospun films exhibit comparatively lower resistance of 25.3 ohm, good fibrous morphology with a diameter being 1 μm. In addition, the electrospun films are cytotoxicity-free and facilitate the growth of cells. It is observed in the MMT assay that after co-cultured with cells for three days, PVA/CNT electrospinning fibrous membranes exhibit a cellular viability that is 18.5 times greater than that of the control group on Day 1. According to all property evaluations, PVA/CNT electrospinning fibrous membranes are a qualified candidate for the use of nervous conduits.

Electrospun nanofibers are unique one-dimensional materials with high surface area to volume ratio which can be used in various applications including in antibacterial application. In this study, we demonstrated a simple fabrication of polyethylene oxide-polypyrrole (PEO-PPy) composite nanofibers with antibacterial properties. The polymerization of pyrrole was conducted using ammonium persulfate (APS) initiator at ambient temperature for 24 h. The resulting PEO-PPy nanofibers were then characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), fourier transform infrared (FTIR), and tensile tests. The morphology of nanofibers observed by SEM revealed that the minimum concentration of PEO was 8 wt % to obtain the bead-free nanofibers. Meanwhile, variation of pyrrole concentration does not alter the morphology of nanofibers significantly. The crystallinity of the nanofibers increased with increasing the PEO amount indicated by two typical peaks located at 2θ = 19°and 23°, respectively. On the other hand, polypyrrole contributed the antibacterial properties significantly to the nanofibers and as a result, the antibacterial activity determined by UV-Vis spectrophotometer increased dramatically with increasing pyrrole concentration from 0.1 to 0.2, 0.3, 0.4, and 0.5 mM. The electrospun nanofiber mats exhibited good antibacterial properties on E. coli and biocompatibility properties on L929 fibroblasts cell.
