摘要

Copper ferrite nanoparticles were synthesised via a green synthesis route and mechanically incorporated into the natural rubber matrix to develop a flexible nanocomposites with modified mechanical, thermal and dielectric properties. The incorporation of copper ferrite alters the stiffness, thermal transport and dielectric response of the natural rubber. While the tensile strength decreases from 0.85 to 0.63 MPa, tensile modulus increases from 0.135 to 0.219 MPa, indicating enhanced stiffness due to restricted polymer chain mobility. A significant reduction in the thermal conductivity from 0.7478 to 0.2259 W m−1 K−1 confirms improved thermal insulation behaviour. Thermal analysis demonstrates delayed degradation and increased thermal stability in the nanocomposites, attributed to strong interfacial interactions and the presence of thermally stable ferrite phases. Dielectric studies reveal enhanced polarisation behaviour at elevated temperatures and frequencies.
