Antimicrobial, mechanical, optical and thermal properties of PVC/ZnO‐EDTA nanocomposite films

Abstract

Covalent surface functionalization of synthesized ZnO nanoparticles (NP)s with ethylenediaminetetraacetic acid (EDTA) was successfully carried out. Modified ZnO‐EDTA NPs as a viable and inexpensive filler were incorporated into poly(vinyl chloride) PVC matrix after their chemical modification to investigate the agglomeration behavior. All prepared materials including modified NPs and PVC/ZnO‐EDTA nanocomposites (NC)s were analyzed by Fourier transform infrared spectroscopy, ultraviolet–visible spectroscopy, thermogravimetric analysis, X‐ray diffraction, field emission scanning electron microscopy and transmission electron microscopy. Fabricated PVC/ZnO‐EDTA NCs were reported to have high transparency and improved mechanical properties compared with PVC. Modified ZnO and the fabricated NCs were shown to exhibit excellent antibacterial activity against two bacteria species: Escherichia coli and Staphylococcus aureus. The obtained NCs could be considered as self‐extinguishing materials on the basis of the LOI values. Copyright © 2016 John Wiley & Sons, Ltd.

Partially Transformation of Zinc Nitrate to Zinc Compounds on PVC Nanofibers at

“…In the literature, it was reported that when ZnO was added to PVC, UV absorption increased and transmittance was decreased [7,8]. Optical reflectance and transmittance plots of nanofibers produced in this study were demonstrated in Figure 8.…”

“…Since corresponding ZnO peaks are not presented at the XRD patterns [18,19], it is very difficult to mention that zinc nitrate was transformed to well crystallize zinc oxide structure in this study. In the literature, it was reported that when ZnO was added to PVC, UV absorption increased and transmittance was decreased [7,8]. Optical reflectance and transmittance plots of nanofibers produced in this study were demonstrated in Figure 8.…”

“…Al-Taa'Y et al investigated the optical properties of different ratio of ZnO nanoparticle loaded PVC, and reported that increasing ZnO content enhances to optical absorption and decreases the optical transmittance [7]. Enhanced transparency and antibacterial properties have been obtained from ZnO nanoparticle embedded PVC where ZnO particles covalently modified with ethylenediaminetetraacetic acid [8]. In another study, optical absorption increase and transmittance decrease with ZnO addition to PVC, and hence such materials can be used for packing due to filtration of UV and visible light [8].…”

Preparation, characterization, and antimicrobial activity of ferrocene‐containing polymeric materials

“…A variety of polymeric matrices, ranging from polyolefins to polyesters, polyurethanes and silicon polymers, together with other materials including glass, titania or nanofibers 11–14 have been investigated for the production of antimicrobial materials. In particular, polyvinyl chloride (PVC) is a versatile polymer widely used for the production of medical devices as well as enteral feeding products and novel materials with antimicrobial activity have been obtained by incorporation of metal oxides, nanoparticles and zeolites, ionic liquids and natural substances into this polymer matrix 15–20 …”

Ultrasonic treatment as recent and environmentally friendly route for the synthesis and characterization of polymer nanocomposite having PVA and biosafe BSA‐modified ZnO nanoparticles

“…In this regard, surface modification of NPs with coupling agents and stabilizers (eg, organic compounds, polymer, proteins etc.) or charging the NP surface to isolate them by electrostatic repulsion was adopted to avoid aggregation …”
