“…However, hydrophobic materials are not suitable for filtration. Therefore, hydrophilic material, e.g., PVP, polyacrylonitrile (PAN), and poly(ethylene glycol) (PEG), can be added to PVC in order to reduce the water contact angle, which means that its hydrophobicity will be reduced [70][71][72]. It was found that when the number of particles in the nanofiber mat increased, it increased the roughness of the mat and eventually increased the water contact angle [73].…”

Polyvinyl chloride (PVC) is a widely used polymer, not only in industry, but also in our daily life. PVC is a material that can be applied in many different fields, such as building and construction, health care, and electronics. In recent decades, the success of electrospinning technology to fabricate nanofibers has expanded the applicability of polymers. PVC nanofibers have been successfully manufactured by electrospinning. By changing the initial electrospinning parameters, it is possible to obtain PVC nanofibers with diameters ranging from a few hundreds of nanometers to several micrometers. PVC nanofibers have many advantages, such as high porosity, high mechanical strength, large surface area, waterproof, and no toxicity. PVC nanofibers have been found to be very useful in many fields with a wide variety of applications such as air filtration systems, water treatment, oil spill treatment, batteries technology, protective clothing, corrosion resistance, and many others. This paper reviews the fabricating method, properties, applications, and prospects of PVC nanofibers.

“…For Ibu and P3 fiber, the absorption band locates at 2942 cm −1 indicates aromatic C−H stretching [41] . The presence of PAN in the fiber structures is confirmed by the typical absorption peak at 2243 cm −1 (−C≡N) [59,74,76] . The vibration bands at 1708 and 1663 cm −1 correspond to C=O stretching in the Ibu and all‐fiber samples containing PVP, respectively [72] .…”

The objective of the present study is to evaluate the pH‐dependent drug release from polyvinylpyrrolidone (PVP)/polyacrylonitrile (PAN)/graphene (Gr) (P1) fibers using a quartz crystal microbalance (QCM). Electrospun fibers for poorly water‐soluble drugs were prepared on the QCM electrode surface through the electrospinning with P1 as the fiber‐forming polymer and drug carrier system and ibuprofen (Ibu) as the model drug. Characterization of the fibers is practiced by X‐ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy in combination with energy‐dispersive X‐ray spectroscopy (SEM‐EDX), thermogravimetric analysis (TGA)‐differential scanning calorimetry (DSC), and water contact angle measurements. The in vitro release kinetic studies of the Ibu were studied using QCM and UV‐vis spectroscopy. The drug delivery properties of the fibers of PVP/PAN/Gr with 5 wt % Ibu (P2) and PVP/PAN/Gr with 10 wt % Ibu (P3) were measured at pH 5.4 and 7.4. In pH 5.4, the cumulative drug release of 19.5 % was procured from the P3 fiber within 24 h, on the other hand; the cumulative drug release of 16 % was acquired in pH 7.4.

“…46 Alamir et al produce nanofiber mats using the electrostatic spinning technique, which are combined with hydrophilic polymers to collect fog from air. 47 It is found that the nanofibers can absorb up to 10% of their weight, and this value increases to 69% in the presence of hydrophilic reagents. Wire electrical discharge machining is employed to create a layered fluted surface with superhydrophilic properties (Figure 2d−f), enabling fog collection with efficiency of 720 mg (h cm 2 ) −1 .…”
