Abstract :
The improvement of optical properties of (PVA-PEG) has been studied. The bio composites were
manufactured with different volumetric concentrations of extract of willow leaves and (PVA-PEG) blend. The FTIR
analysis of composites were examined. The optical properties studied at wavelength ranged (220-800) nm. The
experimental results presented that the optical properties of bio composites changed with increase of extract of willow
leaves concentrations.
