Main Article Content
In this research work, polypropylene composites were synthesized using copper acetate mixed with polypropylene. SEM results showed the distribution of copper oxide cluster in polypropylene matrix, which increases in size with increasing copper oxide content. The bending strength decreases with increasing copper oxide. The outcome was confirmed by the universal testing machine. The optical absorption can be increased with increasing copper oxide content. In addition, the permittivity of these polypropylene composites are linearly altered with copper oxide content, probably due to surface charge accumulation.
