Book Part Citation - Scopus: 12Green electrospinning(De Gruyter, 2019) Horzum,N.; Muñoz-Espí,R.; Hood,M.A.; Demir,M.M.; Crespy,D.In the last two decades, electrospinning has grown in popularity; however, the majority of the setups are based on solution processing from toxic organic solvents. As green processing and environmental stewardship have also become important in recent years, for political and economic reasons, the subsequent increase in demand for the scaling up of electrospinning requires that an environmentally toxin-free process be championed. This book comprehensively addresses clean and safe electrospinning for the fabrication of green nanofibers and evaluates their potential applications. © 2019 Walter de Gruyter GmbH, Berlin/Boston.

The increase in demand for scaling up electrospinning in recent years therefore requires an environmentally friendly process free of organic solvents. This book addresses techniques for clean and safe electrospinning in the fabrication of green nanofibers and their potential applications. © 2019 Walter de Gruyter GmbH, Berlin/Boston.

The consumption of plastics has increased exponentially due to their low cost, chemical resistance, lightness, durability and ability to combine with other materials. However, plastic materials represent high tonnage in urban wastes, and it is known that these plastics discarded at the end of their useful life by filling the landfill sites. Electrospinning is a well-established and versatile technique for the fabrication of submicron fibers. In addition, it is a promising approach for the recycling of waste polymers without using complex methodologies. In this chapter, utilization of electrospinning approach for the recycling of daily wastes will be discussed. The literature about the daily wastes of both synthetic materials and natural/agricultural materials will be analyzed, and the applications of these materials will be given in detail. © 2019 Walter de Gruyter GmbH, Berlin/Boston.

Green fibers are particularly interesting for biomedical applications such as tissue engineering, drug delivery, biocompatible scaffolds, biosensors, and for photovoltaics, supercapacitors, fuel cells, battery components as energy fields, and for filtration membranes as environmental applications. In this chapter, we classified green electrospinning into two groups: (i) green processes as polymer free, solvent free, solution, and colloid electrospinning, (ii) green fibers from natural polymers and blends. © 2019 Walter de Gruyter GmbH, Berlin/Boston.

The electrospun fibers form a unique structure which have a very large surface area-to-volume ratio and high porosity with very small pore size. Therefore, electrospun fibers could be a very promising material for many biomedical applications such as drug delivery, wound dressing, artificial organ and medical prosthesis [2, 3]. Polymer-based drug delivery systems are used to improve the therapeutic properties of drugs in a safer, effective and reliable manner [4]. The variety of biodegradable polymers can be electrospinnable [5]. At present, researches on biodegradable nanofibers focus on development for delivering drugs and releasing them continuously over a period of time. Drug delivery with polymeric nanofibers with higher drug encapsulation efficiency and better stability than other drug formulations possess high surface-to-volume ratio which would accelerate the solubility of drug in the aqueous solution and enhance the efficiency of the drug [6, 7]. Gelatin is a natural biopolymer derived from animal collagen, having a long history of safe use in pharmaceuticals, cosmetics as well as food products [8]. Because of its great biocompatibility and biodegradability properties, gelatin has a broad applications in biomedical fields, especially as a drug delivery carrier [9]. In the current work electrospun fibers were developed as a new system for the delivery and release of an anticancer agent doxorubicin via electrospinning technique. The morphology of the fibers was analyzed by scanning electron microscopy(SEM), fourier transform infrared spectroscopy (FTIR). The fibers were made from gelatin as a biodegradable polymer and the release of doxorubicin was followed by UV-vis spectroscopy in phosphate buffer of pH 7.4 at 25 °C and 37 °C. The release profiles from gelatin electrospun fiber mats were compared with casting films with the same composition. © 2016, Avestia Publishing. All rights reserved.
