استخلاص السليللوز من قشور الدخن ودراسة الخواص البصرية للبوليمر المستخلص

Abstract EN

In this work, the cellulose Extraction of millet husks , that were thrown as waste from bird feed was extracted, as cellulose was extracted in scientific and accurate methods and re-extracted several times in order to obtain the best result.

The cellulose extracted was also diagnosed with the technology of optical microscopy (FESEM) and performed for thin films The study of the optical properties within the wavelength range (300-900nm) and at a thickness of 100nm, as the nanoparticles were prepared by the method of spin coating, from which the optical absorbance was calculated, which has a fixed value for the measured wavelengths and tan of 50%, and the absorption coefficient (α), refractive index (n), inactivity coefficient (k) as a function of wavelength and optical energy gap (Eg).
