Synthesis and Characterization of a Novel Membrane Based on Poly (2-Ethyl Oxazoline) and Poly (Propylene) Graft Copolymer for Potential Food Packaging and Medical Applications
Baki Hazer, Zeynep Karahaliloglu, Özgür Keleş
TL;DR
A new membrane material combining polypropylene and a water-soluble antibacterial polymer was developed for food packaging and medical uses.
Contribution
A novel graft copolymer combining polypropylene and poly(2-ethyl oxazoline) was synthesized and tested for antibacterial and anticancer properties.
Findings
The PP-polyEtOx graft copolymer showed better water vapor transmission rates than polyethylene terephthalate membranes.
The material reduced colony counts of S. aureus and E. coli and inhibited HT-29 cancer cell viability.
Abstract
Cost-effective olefin polymers have been producing several hundred million tons of olefins each year. They have material properties suitable for packaging and biomedical applications. Among them, chlorinated polypropylene (PP-Cl) was functionalized with poly(2-ethyl oxazoline) (PP-polyEtOx) to obtain a biomimetic PP-polyEtOx conjugate polymer material. Poly(2-ethyl oxazoline) is a water-soluble antibacterial and anticancer polymer. The combination of this bioactive polymer with the elastic properties of polypropylene via graft copolymerization provided a potential active food packaging material. Here, the obtained PP-polyEtOx graft copolymer was characterized structurally using 1H NMR, Fourier transform infrared (FTIR), and X-ray photoelectron spectroscopy (XPS). The water vapor transmission rates of the obtained membranes are better than those of polyethylene terephthalate membrane.…
