Experimental Study of Thermal Conductivity of Polyethylene Copper Oxide Nanocomposite
نویسندگان
چکیده
The demand for new, thermally conducting light weight and anti-corrosive materials is tried by incorporating Copper Oxide (CuO) nano powder in polyethylene matrix material. A laboratory level electro deposition technique is adopted here to prepare Copper Oxide (CuO) nano particles. Their phase composition is confirmed with X-Ray diffraction peaks and verified with standard JCPDS file for Copper Oxide (CuO). The High Density Polyethylene (HDPE) grade is chosen and is mixed with Copper Oxide (CuO) at three different proportions (1 %, 2 % & 3 % of its weight) in a twin screw extruder by melt mixing method. Further by conducting Scanning Electron Microscopy on these samples indicate different weight % Copper Oxide (CuO) nano powder High density polyethylene sample shows better homogeneity and bonding between Copper Oxide (CuO) and polyethylene and also there is no pores seen on its surface. This also confirms the satisfactory formation of conducting nano filler network. The obtained thermal conductivity for 3 weight % Copper Oxide (CuO) nano powder High density polyethylene sample is 8 times greater than virgin sample which is due to reduction of phonon scattering by this conducting Copper Oxide (CuO) nano filler. KEYWORDS--Polyethylene, Copper Oxide (CuO), Nanocomposite, Thermal Conductivity.
