Poly(vinyl alcohol)-poly(vinyl pyrrolidone) blends: Preparation and characterization for a prospective medical application
Poly(vinyl alcohol) and poly(vinyl pyrrolidone) were blended and films were obtained by casting method. Glutaraldehyde, hydrochloric acid and lactic acid were added to investigate their effect on mechanical properties, swelling and solubility of the blends with the aim to find a possible material candidate for medium or long term implants. Combination of all three additives (lactic acid, glutar...
متن کاملEvaluation of morphology and cell behaviour of a novel synthesized electrospun poly(vinyl pyrrolidone)/poly(vinyl alcohol)/hydroxyapatite nanofibers
Objective(s): Three-dimensional structures such as nanofibrous scaffolds are being used in biomedical engineering as well as provide a site for cells to attach and proliferate leading to tissue formation. In the present study, poly(vinyl pyrrolidone) (PVP)/ poly(vinyl alcohol)(PVA) hybrid nanofibrous scaffold was synthesized by electrospinning. Materials and Methods: The effect of adding nano h...
متن کاملPreparation and Characterization of Aligned and Random Nanofibrous Nanocomposite Scaffolds of Poly (Vinyl Alcohol), Poly (e-Caprolactone) and Nanohydroxyapatite
Nanofibrous scaffolds produced by electrospinning have attracted much attention, recently. Aligned and random nanofibrous scaffolds of poly (vinyl alcohol) (PVA), poly (ε-caprolactone) (PCL) and nanohydroxyapatite (nHA) were fabricated by electrospinning method in this study. The composite nanofibrous scaffolds were subjected to detailed analysis. Morphological investigations revealed that the...
متن کاملImpedance Analysis of Gellan Gum - Poly(vinyl pyrrolidone) Membranes
This paper presents the impedance study of low acyl gellan gum/poly(vinyl pyrrolidone) blend as a host matrix for ion conduction. Low salt content of lithium perchlorate was added into the blend polymer host and the membranes were prepared by the means of solution casting method. The temperature-conductivity of the investigated samples follows the Vogel-Tamann-Fulcher rule. The occurrence of el...
متن کاملPreparation and Properties of Electrospun Poly (Vinyl Pyrrolidone)/Cellulose Nanocrystal/Silver Nanoparticle Composite Fibers
Poly (vinyl pyrrolidone) (PVP)/cellulose nanocrystal (CNC)/silver nanoparticle composite fibers were prepared via electrospinning using N,N'-dimethylformamide (DMF) as a solvent. Rheology, morphology, thermal properties, mechanical properties, and antimicrobial activity of nanocomposites were characterized as a function of material composition. The PVP/CNC/Ag electrospun suspensions exhibited h...
