Abstract

This research work presents a comparative study for morphological effects of high accelerated and non-accelerated lead ions on polymers. The ions are produced using lead target by high powered pulsed Nd: YAG laser with wavelength of 1.064 µm, energy of 10 mJ, pulse duration of 12 ns, and power of 1.1 MW, at low pressure of ~10-3 torr. The acceleration voltage of 500 V is used to accelerate Lead ions on polyvinylchloride (PVC). The PVC samples are also irradiated without applying any potential, just to have a comparison of both types of irradiation. The samples were irradiated for 300 shots for each sample. The morphological changes were observed using Transmission optical microscope (Motic DMB series). The results showed the morphological changes in polymeric samples for accelerating potential of 500 V and 0 V. Long chain formation of laser accelerated lead ions is observed at 500 V as compared to the 0 V. The ion induced dragging effects are shown for 0 V which depend upon the energy of lead ions and also on the properties of the polymeric sample.
