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...

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...

The first major success of polymer nanocomposites, where the filler has at least one dimension in the nanoscale, was reported by Kojima, Usuki et al. [1] from the Toyota Central R&D group. They demonstrated that nylon6/clay nanocomposites showed significant improvement in the mechanical and the thermal properties. Since then, works on the polymer nanocomposites have been conducted on a wide var...

In this work agar- and borax-based hydrogels with without the addition of poly(vinyl alcohol) (PVA) at different concentrations were synthesized. Hydrogels modified by same amount acetylsalicylic acid (ASA) which exhibits antithrombotic properties. The effect modification ASA on properties was analyzed.

This article is focused on the impact of different binder mixtures on the performances of paper surface and printability. The coating properties were studied with the chosen silica pigment, and the binder consisted of vinyl acetate copolymer and polyvinyl alcohol with different ratios, followed by the measurement of smoothness, whiteness, and surface strength. The inkjet image quality was asses...

Article history: Received January 26, 2013 Received in Revised form May 10, 2013 Accepted 20 May 2013 Available online 24 May 2013 Superabsorbent hydrogels based on poly(vinyl alcohol) were prepared by a crosslinking technique using glutaraldehyde as a crosslinker. The hydrogel structure was confirmed using scanning electron microscopy (SEM). Results from SEM observation showed a porous structu...

Abstract Herein we report the optical properties of different amounts zinc halide added poly(vinyl alcohol) polymer composites and characterised for spectral absorbance. The shown appreciable as established by a UV–visible techniques. were analysed determining parameters such band tail energy localised states, bandgap, susceptibility.
