Abstract
Effect of Thickness variation on The Optical Properties of (Poly Vinyl Alcohol : Green Methyl) Films
Highlights
Poly(vinyl alcohol) (PVA), is a water-processable polymer, with excellent chemical resistance, optical and physical properties which recommend it and itscomposites for broad industrial uses
In the present work is to investigate the optical properties of poly vinyl alcohol (PVA) doped with 4% of Green methyl with different thicknesses by solvent cast method
Figure (1) shows the of Poly Vinyl Alcohol : Green Methyl) Films for different thickness as a function of wavelength we can observe that the transmittance decreases with increasing the thickness This may be attributed to the creation of levels at the energy band by increasing thickness and this leads to the shift of peak to smaller energies
Summary
Poly(vinyl alcohol) (PVA), is a water-processable polymer, with excellent chemical resistance, optical and physical properties which recommend it and itscomposites for broad industrial uses. It is observed that doping a polymer with metal salts has significant effect on their physical properties including optical, Jaafar Sadeq Mohammed and electrical properties. These changes in physical properties, depend on the chemical nature of the dopant and the way in which they interact with the host polymer [4,5,6]. In the present work is to investigate the optical properties of poly vinyl alcohol (PVA) doped with 4% of Green methyl with different thicknesses by solvent cast method. Absorbance and transmittance measurement were carried out using UV/VIS Spectrophoto meters in the wave length range (190 – 1100) nm
