“…AITC is a liquid compound at room temperature, so we did not run XRD analysis for pure AITC. PVA is a semi-crystalline polymer and the XRD of PVA-NF has shown a broad diffraction at around 2Â ∼ 19.6 • [33]. XRD pattern of PVA/AITC-NF was similar to PVA-NF, thus PVA keeps its semi-crystalline structure after incorporation of AITC.…”

a b s t r a c tAllyl isothiocyanate (AITC) is known as an efficient antibacterial agent but it has a very high volatility. Herein, AITC and AITC/␤-cyclodextrin (CD)-inclusion complex (IC) incorporated in polyvinyl alcohol (PVA) nanofibers were produced via electrospinning. SEM images elucidated that incorporation of AITC and AITC/␤-CD-IC into polymer matrix did not affect the bead-free fiber morphology of PVA nanofibers. 1 H-NMR and headspace GC-MS analyses revealed that very low amount of AITC was remained in PVA/AITC-NF because of the rapid evaporation of AITC during the electrospinning process. Nevertheless, much higher amount of AITC was preserved in the PVA/AITC/␤-CD-IC-NF due to the CD inclusion complexation. The sustained release of AITC from nanofibers was evaluated at 30 • C, 50 • C and 75 • C via headspace GC-MS. When compared to PVA/AITC-NF, PVA/AITC/␤-CD-IC-NF has shown higher antibacterial activity against Escherichia coli and Staphylococcus aureus due to the presence of higher amount of AITC in this sample which was preserved by CD-IC.

“…Chitosan/MMT nanocomposites have been prepared for adsorption [95] and drug release [96] due to the unique properties of MMT. Submicron fibers of the composites of PVA, chi- tosan oligosaccharide (COS) and MMT were prepared using electrospinning method with aqueous solutions [97]. The PVA/COS ratio and MMT concentration play important roles in nanofiber mat properties.…”

Chitosan is soluble in most acids. The protonation of the amino groups on the chitosan backbone inhibits the electrospinnability of pure chitosan. Recently, electrospinning of nanofibers based on chitosan has been widely researched and numerous nanofibers containing chitosan have been prepared by decreasing the number of the free amino groups of chitosan as the nanofibiers have enormous possibilities for better utilization in various areas. This article reviews the preparations and properties of the nanofibers which were electrospun from pure chitosan, blends of chitosan and synthetic polymers, blends of chitosan and protein, chitosan derivatives, as well as blends of chitosan and inorganic nanoparticles, respectively. The applications of the nanofibers containing chitosan such as enzyme immobilization, filtration, wound dressing, tissue engineering, drug delivery and catalysis are also summarized in detail

“…8 Combining COS with PVA for electrospinning can reportedly improve fiber uniformity, especially for electrospinning in dilute solutions. 9 Silver has antimicrobial properties due to its capacity to interact strongly with the thiol group of compounds found in the respiratory enzymes of bacterial cells. Further, silver nanoparticles (AgNPs) display more efficient antimicrobial properties than other salts due to their extremely large surface area, which provides better contact with microorganisms.…”
