Study the Rheological and Optical Properties Of Nickel Ferrite/PMMA Nano-Compsite Growth In Crude Oil Via Laser Ablation

A novel polymeric nanocomposite pour point depressant (PPD), based on Nickel Ferrite and (Polymethyl methacrylate - PMMA) polymer was synthesized and characterized. In this research the sample prepared in tow steps, the first step included prepared the sample to be ablated by using mixing kneading method formed as a Circular tablet contain Nickel Ferrite/PMMA. Then the sample ablated by using Nd:YAG laser with (1064 nm) wavelength,(600 mJ) energy,(6Hz) frequency and (100 pulses) for the tow sample which immersed in dilute Crude Oil (obtained from the Rumaila Oil Field in Southern Iraq). The optical properties of samples showed that the same behaviour but with blue shifting. The rheological properties showed that the viscosity increased as the polymer increased in samples uneven stability in the value of viscosity of the sample has low polymer ratio. The density almost doubled with same ablations' pulses.
