    Preparation and characterization of polyvinyl alcohol based copolymers as wound dressing fibers
    (Taylor and Francis Inc., 2015) Aytimur, Arda; Koçyiğit, Serhat; Uslu, İbrahim; Gökmeşe, Faruk
    Biocompatible polyvinyl alcohol/polyethylene glycol and polyvinyl alcohol/polypropylene glycol copolymer mats were prepared by electrospinning. The composite fiber mats were subjected to detailed physical analysis complemented by scanning electron microscopy and Fourier transformations infrared spectroscopy. Scanning electron microscopy images showed that the morphology and diameters of the fibers were mainly affected by the types of polymers and their copolymer compositions. Microbial culture results showed that among the tested fibrous mats polyvinyl alcohol/50% polyethylene glycol gave the best results in preventing the cell attachment and proliferation. This novel electrospun matrix would be used as potential wound dressing material for skin regeneration. © 2015 Taylor and Francis Group, LLC.

    Preparation and Characterization of PVA/PVP Nanofibers as Promising Materials for Wound Dressing
    (2013) Gökmeşe, Faruk; Uslu, İbrahim; Aytimur, Arda
    The PVA/PVP, PVA/PVP with 5% and 10% chitosan and PVA/PVP-Iodine fibers were produced via electrospinning technique. Their morphological and chemical characteristics were examined with SEM, TGA, FT-IR, viscometer and four-point probe conductivity measurement apparatus. The addition of chitosan increased the viscosity and the electrical conductivity of the polymer. The increase chitosan contents resulted in the diameters of the fibers smaller than expected. This was attributed to the increase in the viscosity of the solution and the electrical conductivity of the resulting fibers. The DSC results show that iodine was efficiently cross-linked with the polymer, forming an amorphous structure. © 2013 Copyright Taylor and Francis Group, LLC.
