In this work, polyvinyl chloride (PVC)/clay nanofiber composites with various contents were fabricated by the electrospinning process. The morphology, porosity, density, and mechanical properties of the nanofiber mats were investigated. In addition, PVC/clay nanofiber mats were characterized by Fourier transform infrared spectroscopy, differential scanning calorimetry, and thermogravimetric analysis. Moreover, the influence of the clay content in the nanofiber mats and its effect on oil sorption capacity were also evaluated. The results show that the clay particle diameter affects the fabrication, morphology, porosity, density, mechanical properties, and sorption capacity of the nanofiber mats. Adding clay in nanofiber composite materials leads to higher porosity and a higher oil sorption capacity. PVC/clay nanofiber mats have a high oil sorption capacity at low temperatures. They exhibit a high potential to be used as materials to eliminate oil spills under arctic conditions.

Oil spill is a serious environmental pollution problem that affects the environment and human health. The immediate and efficient removal of oil spill has become an urgent problem. In recent decades, electrospinning technology has become an effective method for fabrication of nanofibers. Electrospun nanofibers have many applications in different fields, such as environment, healthcare, electrical field, and electronics. The present paper has studied the capacity of polyvinyl chloride nanofibers, which have been successfully obtained by electrospinning method for removal of oil from water. The morphology and hydrophobicity of nanofibers were studied. The sorption capacity of nanofibers has been investigated for various oils such as motor oil, hydraulic oil, and crude oil. The rate of oil sorption versus time, the effect of oil concentration, and temperature on the oil sorption capacity were analyzed. The results showed that polyvinyl chloride nanofibers were able to completely absorb oil without absorbing water. In addition, the results of our research showed that polyvinyl chloride nanofiber’s oil sorption capacity is inversely proportional to the temperature. Given these points, our research showed the enormous potential that polyvinyl chloride nanofibers have for removal of oil spill in water, due to their effectiveness and quickly sorption effect.

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.

This paper investigates the mechanical properties of oriented polyvinyl chloride (PVC) nanofiber mats, which, were obtained by electrospinning a PVC solution. PVC was dissolved in a solvent mixture of tetrahydrofuran/dimethylformamide. Electrospinning parameters used in our work were, voltage 20 kV; flow rate 0.5 mL/h; the distance between the syringe tip and collector was 15 cm. The rotating speed of the drum collector was varied from 500 to 2500 rpm with a range of 500 rpm. Nanofiber mats were characterized by scanning electron microscope, thermogravimetric analysis, differential scanning calorimetry methods. The mechanical properties of PVC nanofiber mats, such as tensile strength, Young’s modulus, thermal degradation, and glass transition temperature were also analyzed. It was shown that, by increasing the collector’s rotation speed from 0 (flat plate collector) to 2500 rpm (drum collector), the average diameter of PVC nanofibers decreased from 313 ± 52 to 229 ± 47 nm. At the same time, it was observed that the mechanical properties of the resulting nanofiber mats were improved: tensile strength increased from 2.2 ± 0.2 MPa to 9.1 ± 0.3 MPa, Young’s modulus from 53 ± 14 to 308 ± 19 MPa. Thermogravimetric analysis measurements showed that there was no difference in the process of thermal degradation of nanofiber mats and PVC powders. On the other hand, the glass transition temperature of nanofiber mats and powders did show different values, such values were 77.5 °C and 83.2 °C, respectively.

The optical properties of the polymer composites consisting of polyvinyl chloride nanofibers and polypropylene films in the frequency range of 0.2–1.0 THz were studied, and the mechanical properties of polyvinyl chloride nanofibers and the structure porosity were investigated. An iterative mathematical model based on effective medium theory was used to describe the effective refractive index and absorption coefficient of the polymer composites. The permittivity tensors of the composites were calculated using the Rytov method. We found that the refractive indices of the composites increased with the increase of polypropylene contents, while absorption coefficients remained the same. The polarization-dependencies of THz optical properties of the composites were relatively low. The proposed composites have the potential to be used as materials for terahertz optical components.
