Abstract. Over the past decades, electrospinning of biopolymers down to nanoscale garnered much interest to address most of the millennia issues related to water treatment. The fabrication of these nanostructured membranes added a new dimension to the current nanotechnologies where a wide range of materials can be processed to their nanosize. Electrospinning is a simple and versatile technique to fabricate unique nanostructured membranes with fascinating properties for a wide spectrum of applications such as filtration and others. These nanostructured membranes, fabricated by electrospinning, were found to be of a paramount importance because of their advanced inherited properties such as large surface-to-volume ratio, as well as tuneable porosity, stability, and high permeability. The extensive research conducted on these materials extended the success of electrospinning not only to bio-based polymer nanofibres, but to their hybrids and their derivatives. The technique also created avenues for advanced and massive production of nanofibres. This paper reviews the recent developments in the electrospinning technique. Electrospinning of biopolymers, their blends and functionalization using metals/metal oxides, and the potential applications of electrospun nanofibrous membranes in water filtration are discussed.

“…As-spun chitin nanofibers had the broad fiber diameter distribution showing that most of them are less than 100 nm [60]. Junkasem et al reported electrospinning of PVA and α-chitin whiskers prepared from shells of Penaeus merguiensis shrimps and produces nanofibrous mat for tissue engineering applications [61]. This investigation was carried out since both PVA had previously been electrospun [62] in water and chitin/PVA nanocomposite films containing α-chitin whiskers have also been fabricated in organic solvent system [63].…”

Intensive studies have been done to a wide range of natural and synthetic polymeric scaffolds which have been done for the use of implantable and temporal devices in tissue engineering. Biodegradable and biocompatible scaffolds having a highly open porous structure with compatible mechanical strength are needed to provide an optimal microenvironment for cell proliferation, migration, differentiation, and guidance for cellular in growth at host tissue. One of the most abundantly available biopolymer chitins and its deacetylated derivatives is chitosan which is non-toxic and biodegradable. It has potential biomedical applications such as tissue engineering scaffolds, wound dressings, separation membranes, antibacterial coatings, stent coatings, and biosensors. Recent literature shows the use of chitin and chitosan in electrospinning to produce scaffolds with improved cytocompatibility, which could mimic the native extra-cellular matrix (ECM). Similarly, silk from the Bombyx mori silkworm, a protein-based natural fiber, having superior machinability, biocompatibility, biodegradation, and bioresorbability, has evolved as an important candidate for biomedical porous material. This chapter focuses on recent advancements made in chitin, chitosan, and silk fibroin-based electrospun nanofibrous scaffolds, emphasizing on tissue engineering for regenerative medicine.

“…The studies have shown increase in tensile properties of nanocomposites for α-chitin whisker (ChW)/PVA (Junkasem et al 2006;Uddin et al 2012), α-ChW/ chitosan films (Sriupayo et al 2005), and α-ChW/soy protein isolate films (Lu et al 2004). In these studies an optimum ChW loading was reported, above which there was negligible improvement in these properties.…”

Biopolymers are an alternative to petroleum-based synthetic polymers that are renewable, do not contribute to environmental pollution, and are biodegradable. However, some of their properties like tensile strength, impact strength, thermal stability, and permeability are not of sufficiently high standard and must be improved. One way to improve the properties of biopolymers and thus enhance their commercial potential is to incorporate nano-sized bio-based reinforcements in the polymers. The composites thus formed are called eco-friendly polymer nanocomposites. The research in these composites has increased substantially in the last few years with a corresponding increase in research papers. These composites are finding applications in various fields like medicine, packaging, electronics, the automotive sector, and the construction industry. Polysaccharide polymers that are abundant in nature are increasingly being used for this purpose. The biopolymers most commonly used in these composites are thermoplastic starch (TPS), polylactic acid (PLA), cellulose acetate, chitosan, polyvinyl alcohol (PVA), and epoxidized plant oils. Some examples of the bio-based reinforcements used in these composites are cellulose nanowhiskers, chitin whiskers, and starch nanoparticles (SNP). Extrusion and injection molding are the most widely used methods for manufacturing of these composites. Results show that incorporation of bio-based nanoreinforcements in biopolymers results in improvement in mechanical properties of these composites. These include tensile, flexural, and impact properties. Poor dispersion and agglomeration of nanoreinforcements in biopolymers and their poor interfacial bonding are issues which impose a limit on these composites' mechanical performance. Various physical and chemical methods for surface treatments of nanoreinforcements are used. These methods have been shown to result in improvements of mechanical properties of these composites. There are a number of other issues like sensitivity to moisture and temperature, expensive recycling processes, high variability in properties, nonlinear mechanical behavior, poor long-term performance, and low impact strength, which are hindering the A.
