Research On Nano-alloy, Nano-carbon And Its Polymer Hybrid Materials Prepared Continuously By Pulsed Laser Ablation

Nano-NiMnCo, FeNiMn, FeNi and NiMn alloy/ethanol sol as well as their nanoparticles were successfully prepared by the novel experiment method established and developed by our group, which is Pulsed Laser Ablation at the Interface of Target Submerged in Flowing Liquid (PLA-IT/SFL). Five kinds of reagent or solution with the different polarity such as water, ethanol, ethyl acetate, benzene and 1‰ polystyrene of benzene were selected as the flowing liquid, and the graphite target was selected as the solid one, so the five kinds of nano-carbon sol and their corresponding carbon nanoparticles were also successfully prepared by the PLA-IT/SFL method. The characterizations and analysis show that the nano-carbon particles' size, distributing, the sol's stability and its spectroscopy speciality are strongly affected by the constitutes and properties of the flowing liquid with different polarity. With the exploiting of two plans, one is that the alloy powder was mixed into the graphite target in advance with the different proportion; another is that the nano alloy/ethanol sol prepared in advance was selected as the flowing liquid, the composite of the nano-carbon and nano-FeNi alloy was successfully prepared by the PLA-IT/SFL method. The characterizations and analysis show that in the first plan that the alloy powder was mixed into the graphite target in advance the alloy can bring the catalysis function on the preparation of nano-carbon, while in the second plan that the nano alloy/ethanol sol prepared in advance was selected as the flowing liquid the nano-alloy in the sol can not bring the evident catalysis function on the preparation of nano-carbon, and the further research was needed. The polymer materials of polystyrene hybridized by nano-carbon with five different percent were successfully prepared by the PLA-IT/SFL method firstly. Thecharacterizations and analysis show that a certain conjugate between the nano-carbon and the size group benzene ring of the polystyrene molecule is produced, it gives rise to the distinct decrease of the glass state temperature (Tg), the increase of the plasticity and the heat resisting property of the polymer materials of polystyrene.
