Abstract :
In this work, bio composites have been prepared by adding the vegetarian lotion of willow solution to
(polyvinyl alcohol- polyethylene glycol) solution blend. Study of optical properties for polymer blend and with
different concentrations of (VLW) have been investigated. The absorption spectra recorded at the wavelength ranges
(200-800) nm. The results show that the absorbance of bio composites are increasing with the increase of the VLW
concentrations. The energy band gap of bio composites decreases with the increase of the VLW concentrations.
Fabrication of humidity sensors by using bio composites has been investigated.
