Abstract
Montmorillonite clay polyester nano composite were successfully prepared by melt insertion method at 5wt%, 10wt%, 15wt%, 20wt% and 25wt% of Montmorillonite clay. The electrical and mechanical properties of the produced composites were studied. Five specimens for each test was analysed. Results obtained indicates that while a drastic decrease in the impact energy of 100 was observed, the maximum tensile strength and young’s modulus values of 50.27 MPa and 8.7 GPa respectively were obtained at 10% filler concentration. The compressive strength increases by 48% and 100% at 15wt% and 20wt% filler concentration respectively. An increase in dielectric strength ( 100%) and capacitance (32%) of the samples with each filler addition of up to 25% with 3 times increase in hardness at 25wt%. was observed
