Electrospinning of Polymer Fibres Using Recycled PET

With increasing usage of polyethylene terephthalate (PET) wastes polluting the oceans and environment, the recycling of PET wastes has become a crucial issue to be overcome. In this article, a review of the different technologies that have been developed to recycle PET wastes and common routes for recycled PET (rPET) is presented. The impacts of varied recycling technologies on the properties of rPET are also discussed herein. The review also focuses on the recovered products by each of the technology and their uses that have been reincorporated into new applications for example, from plastic bottle wastes to 3D scaffolds for biomedical application. Different recycling technologies such as reactive extrusion, chemical recycling and dissolution/precipitation exhibit specific properties due to the influence of the different concepts from one technology to another. A new trend called electrospinning of rPET to produce nanofibers has also garnered attention to be used for different applications. This article will first introduce the recycling technologies concept, and then the properties of the recovered product will be discussed and finally, we will focus on the applications of rPET produced from each of the technologies in various fields such as construction, textile, filtration, and biomedical applications.

“…During the process white, visible PET fibers formed between the tip of the needle and the collector. This is an undesired phenomenon that is most probably due the high evaporation rate of DCM, since we did not observe this earlier, when only TFA was used as solvent [10]. Using DCM:TFA 80:20 solvent ratio to solubilize PET resulted a stable electrospinning process, and the above-mentioned premature fiber solidification did not occur.…”

Polyethylene terephthalate fiber mats were prepared by solution electrospinning with average fiber diameters ranging from 150 nm to 500 nm depending on the processing conditions. The minimum amount of trifluoracetic acid was determined at which the electrospinning process generates randomly oriented and smooth surfaced fibers. A three factorial Box-Behnken experimental design was used to determine the effect of the processing parameters on the resulting fiber diameter. It was found that the dichloromethane: trifluoroacetic acid 80:20 (wt:wt) solvent system generates a robust electrospinning system, where only the applied voltage shows statistical significance.

“…The result shows that the filters are effective in removing the beads with diameters of 1 and 2 μm in the solution, but they are ineffective for removing the particles under 500 nm. Similarly, Attila et al electrospun recycled PET to polymer fibers with diameters ranging from 200 to 600 nm, with potential use in filtration [ 93 ]. In addition, electrospun recycled PET can be applied in energy storage [ 77 ], antibiotics [ 94 ], electromagnetic shielding, [ 95 ] and so on.…”

The accumulation of plastic waste resulting from the increasing demand for non-degradable plastics has led to a global environmental crisis. The severe environmental and economic drawbacks of inefficient, expensive, and impractical traditional waste disposal methods, such as landfills, incineration, plastic recycling, and energy production, limit the expansion of their applications to solving the plastic waste problem. Finding novel ways to manage the large amount of disposed plastic waste is urgent. Until now, one of the most valuable strategies for the handling of plastic waste has been to reutilize the waste as raw material for the preparation of functional and high-value products. Electrospun micro/nanofibers have drawn much attention in recent years due to their advantages of small diameter, large specific area, and excellent physicochemical features. Thus, electrospinning recycled plastic waste into micro/nanofibers creates diverse opportunities to deal with the environmental issue caused by the growing accumulation of plastic waste. This paper presents a review of recycling and reutilizing polymer waste via electrospinning. Firstly, the advantages of the electrospinning approach to recycling plastic waste are summarized. Then, the studies of electrospun recycled plastic waste are concluded. Finally, the challenges and future perspectives of electrospun recycled plastic waste are provided. In conclusion, this paper aims to provide a comprehensive overview of electrospun recycled plastic waste for researchers to develop further studies.
