Effect of addition of (Cu and CuO) on the thermal properties of poly (methyl methacrylate)

The (PMM-Cu) and (PMMA-CuO) Composites have been prepared casting mathed. The X-ray diffraction (XRD) test has been carried for PMMA, Cu, CuO, (PMMA-Cu) Composite and (PMMA-CuO) Composite for Characterization them which were matched with ASTM. The (Cu and CuO), Particles destitution into PMMA- Matrix were illustrated by optical microscope images. We have measured the thermal conductivity for all sample by using Lee‘s disc. Results showed increasing of thermal conductivity for composites compared to the pure PMMA, Moreover; the (PMMA-Cu) has biggest value. The activation energies (Ea) determined by Flynn-Wall- Ozawa (FWO) method by using thermo Gravimetric analysis (TGA) in an inert atmosphere at varied heating rates. Also it has been concluded an increasing of (Ea) for PMMA, (PMMA-Cu) Composite, and (PMMA-CuO) Composite Consequently.
