Abstract:
In this study, the optical properties, in particular absorption coefficient and transparency of Linear Low Density Polyethylene (LLDPE) doped with Zinc Oxide nano particles were investigated within different weight percent namely (0, 5, 10, 15,20% wt) was prepared , using diode laser (915 nm ,80mW) and (820nm,200mW) with different power were used to investigate the absorption coefficient and transparency of LLDPE with each weight percent adding of ZnO nanoparticles, The results indicates that the ZnO / LLDPE nanocomposites after some improvement may be used as good mechanism to reduce the intensities of high power laser which using medical, industrial ,engineering ,and research fields (laser attenuator).
