Fabrication and Electric Characterization of SR/MWCNTs Nanocomposites for Piezoelectric Sensors under Thermal Conditions

Nanotubes with multi-walled structures have the ability of changing the characterization of poly (Silicone Rubber) nanocomposites. In this way, silicone rubber/multiwalled carbon nanotubes (SR/MWCNTs) nanocomposite is achieved by reaction with multifunctional. A new design of SR/MWCNT nanocomposites was developed as a result of experiments to clarify the advantages of filling the MWCNTs with different patterns within the dielectrics. As part of this work, silicone rubber/multiwalled carbon nanotube nanocomposites and room temperature vulcanization (RTV) methods were used to fabricate piezoelectric sensors. The analysis of the frequency response of SR/MWCNT nanocomposites has been conducted under variable thermal conditions (20–40°C). This study succeeded in applying poly (Silicon Rubber) nanocomposites as piezoelectric sensors by exhibiting new electrical characteristics (resistance, capacitance, real and imaginary impedance) under various thermal conditions based on certain types and concentrations of MWCNTs.
