Polymer composites based on polyvinyl chloride nanofibers and polypropylene films for terahertz photonics

Abstract

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.

A Review on Electrospun PVC Nanofibers: Fabrication, Properties, and Application

“…Zhang et al [119] have fabricated composites from PVC nanofiber mats and PP films (Figure 10). The resulting material has a relatively constant index of refraction and has a low absorption coefficient; hence PVC/PP composite has the potential to be used as a material for terahertz optical components.…”

Electrospun Nanofibers from Waste Polyvinyl Chloride Loaded Silver and Titanium Dioxide for Water Treatment Applications

“…The morphology and size of the nanofiber can be controlled by adjusting the parameters of solution (such as surface tension, viscosity, and conductivity), processing (such as applied voltage, the distance of the needle tip to a collector, and solution flow rate), and environmental (such as humidity). 18,19 The PVC pure polymer as a composite nanofiber has been studied for various studies including applications for the methanol microsensor, 20 terahertz optical component, 21 heavy metal removal, 22 etc. To our knowledge, the PVC waste is rarely studied as the nanofiber area.…”

High-Porosity Polymer Composite for Removing Oil Spills in Cold Regions

“…21 PVC nanofibers have been successfully fabricated and have the potential for their implementation in many areas such as air filtration, 22 water treatment, 23 oil−water separation, 24 anticorrosion materials, 25 and materials for terahertz optical components. 26 However, the research on PVC/clay nanofiber fabrication is still lacking. Adding clay in PVC solution in order to fabricate nanofiber mats promises to increase its mechanical strength and oil sorption capacity, from which we can obtain materials with good oil sorption capacity and can be applied for oil−water separation.…”
