Abstract

For a wide variety of innovation, nano-technology is an umbrella term. Nano-technology and Nano-science is an exceptional multidisciplinary field of technology and applied science proposed to understand, use and create molecular and atomic-scale structures. Plasma Nanoscience is an extremely fascinating and fertile field where many exciting discoveries and feasible applications can be anticipated in the years ahead. Plasma nano-science research bridges the nano-technology and nano-science, physics of plasma and gas discharges. The most widely recognized types of plasma reactors and plasma utilized in the nanoscale plasma processing and synthesis is low and high pressure, thermal plasma, liquid-plasma interaction and etc. In the field of plasma science and technology, microencapsulation through liquid-plasma interaction methods is turning into an undeniably significant topic. In numerous applications extending from material science, health treatment and ecological remediation the interaction of non-equilibrium plasma with fluid state is significant. Silver coated copper nanorods have been one of the intriguing materials in micro-electronic engineering because of their extraordinary thermal and electrical properties. Copper rods show dominant electrical, mechanical and optical properties and held great promise for low-cost fabrication. The oxidation of the copper nanowires and strong thermal stability can be well suppressed by the encapsulation of copper rods with silver nanoparticles. Microencapsulation of copper nanowires with silver nanoparticles is done through DC thermal plasma. In this technique, silver coated copper nanowires synthesized through silver nitrate, fructose and sucrose. The samples were prepared through the various concentration ratio of fructose and sucrose. During the synthesis process, samples dried at 90  temperature in an oven and annealed at 300  for one hour. The samples were prepared for further characterization. XRD and SEM technique were used to explain structure, phase and particles size and surface morphology. Thermo gravimetry analysis was used to elaborate the thermal behavior of metallic nanowires.
