Copper Nanofluids: A Facile Synthetic Approach

摘要

The thermal conductivity of the fluid plays an important role in developing energy efficient devices. Modern technologies leading to device miniaturization has led to pursuing better heat transfer fluids which show promising influence. To ameliorate the thermal properties of conventional cooling fluids, development of nanofluids came into being. Herein we report a mild, reliable and one step solution phase synthesis of copper nanofluid by reducing copper acetate with ascorbic acid in the presence of sodium lauryl sulfate as stabilizing agent. The effect of reaction parameters on the reaction rate and size of the synthesized particles was studied. The as synthesized particles were characterized by XRD, TEM, SAED, EDX and UV-Vis techniques. Thermal conductivity and rheological measurements were carried out on the fluid. Sedimentation measurements showed a stability period of 8 weeks. This method is simple, facile, well controlled surfactant assisted route for the synthesis of stable copper nanofluids.
