Improvement Optical Properties of PVA/ TiO2 and PVA/ ZnO Nanocomposites [PDF]

open access: yesAl-Mustansiriyah Journal of Science, 2019
The optical properties of polyvinyl alcohol (PVA) doped TiO2 and ZnO nanoparticles respectively, were studied. PVA/TiO2 and PVA/ZnO nanoparticles were prepared by the pulsed laser ablation technique (PLA).The optical properties of PVA/ TiO2 and PVA/ ZnO nanocomposite solution have been investigated by transmittance data and absorption spectra.

Electrospun PVA–PANI and PVA–PANI– composite nanofibers

open access: yesScientia Iranica, 2011
AbstractDoped polyaniline (PANI) was obtained by the polymerization of aniline, using chemical oxidative polymerization in the presence of ammonium peroxydisulfate [(NH4)2S2O8]. The doped PANI was dedoped by ammonia solution. The electrospinning method was applied to solutions involving PANI–PVA, PANI–PVA–AgNO3, where PV A=poly(vinyl alcohol) and PANI ...

The Study of the Swelling Degree of the PVA Hydrogel with varying concentrations of PVA

open access: yesJournal of Physics: Conference Series, 2022
Abstract Hydrogel is composed of a three-dimensional network of hydrophilic polymers and can swell when placed in an aqueous media. Polyvinyl alcohol (PVA) is a common polymer used to produce hydrogels because it has biocompatibility, non-toxicity, chemical stability, low cost, and excellent mechanical strength.
