Study of PDMS-based flexible conductive elastomeric composite filled with rGO-CaCO₃ nanocomposite

Abstract

In this paper, the authors developed a nanocomposite and nano-filled conductive elastomer through a simple and novel approach. First, the rGO-CaCO3 nanocomposite was synthesized by varying the wt.% of rGO. After that, the nanocomposite unified into the PDMS in the ratio 1:4 (1-part nanocomposite and 4-part PDMS). The influence of doping nanocomposite into the PDMS was thoroughly studied using FESEM, XRD, Raman, XPS, and UV-Vis characterizations. It has been concluded that the doping of nanocomposite enhances the electrical, structural, and optical properties of the PDMS. Absorbance was also, improved, and the optical band gap energy was decreased significantly.
