Evaluation 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 کاملPoly(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 کاملSynthesis of pH Sensitive Hydrogels Based on Poly Vinyl Alcohol and Poly Acrylic Acid
In this research, hydrogels based on poly vinyl alcohol and poly acrylic acid blend were prepared which were cross-linked by applied thermal conditions. Afterward, effects of time and heating on water uptake were investigated. The highest water uptake value exhibited by the sample that was heated for 20 min. at 110 ºC was about 2129% after 4 days at equilibrium state. Hydrogels exhibited p...
متن کاملIntramolecular crosslinking of poly(vinyl alcohol)
Poly(vinyl alcohol) is crosslinked in dilute solution (c = 0.1 wt%) with glutaraldehyde. The reaction product is characterized by viscometry and gel permeation chromatography (g.p.c.). The intrinsic viscosity decreases with increasing degree of crosslinking and does not depend on temperature. G.p.c. reveals that the reaction product is not homogeneous, but consists of a mixture of particles wit...
متن کاملFunctionalized Antimicrobial Electrospun Poly (vinyl alcohol) Nanowebs
Electrospun poly (vinyl alcohol) [PVA] nanowebs functionalized with a commercially available microbiocidal solution ReputexTM 20 were prepared. The active ingredient of ReputexTM 20 is polyhexamethylene biguanides, a safe antiseptic. Fourier Transform Infrared spectroscopy confirmed the functionalization of PVA nanowebs. Functionalized nanowebs were characterized by evaluating their antimicrobi...
