Enhanced optical, thermal and electrical properties of chlorinated natural rubber/zinc ferrite nanocomposites for flexible electrochemical devices

K. Parvathi et al.

Summary: This work investigates the optical, thermal stability, and temperature-dependent electrical properties of chlorinated natural rubber/zinc ferrite nanocomposites. The insertion of zinc ferrite into the rubber matrix leads to a decrease in bandgap energy. The nanocomposites exhibit enhanced thermal stability and electrical properties compared to the parent polymer. Additionally, the conductivity of the nanocomposites shows a non-ohmic behavior, indicating a dynamic relaxation process. The experimental results are in good agreement with theoretical models, suggesting the presence of interfacial interactions in the nanocomposites. These findings are significant for the development of highly-durable flexible electronic devices, actuators, supercapacitors, and elastomeric pressure sensors.
