Tailoring mechanical and electrical properties of polydimethylsiloxane nanocomposites With graphene and carbon nanotubes for wearable electronics

We explored the use of soft and flexible graphene (Gr)-reinforced polydimethylsiloxane (PDMS; Gr-PDMS) Gr-carbon nanotube (CNT)-reinforced PDMS (Gr-CNT-PDMS) as nanocomposites (NCPs) in wearable electronic applications investigated their mechanical electrical properties. Specifically, we evaluated reinforcement NCPs by performing Shore scleroscope hardness machine-washing tests properties using a four-point probe. The results revealed that Gr or CNT concentrations increased, NCPs’ surface resistance increased decreased, respectively. Scanning electron microscopy formation layered polymeric structures Gr-PDMS NCPs, contributing to increase decrease resistance. Furthermore, bending changes were positively correlated with concentration. low exhibited no substantial after tests. However, for PDMS, concentration (>5 wt.%), cross-sectional morphology observed 500 cycles differed substantially from before Additionally, influence one-dimensional (CNT) two-dimensional (Gr) nanomaterials on samples was investigated. aim this study is highlight importance considering different developing high-performance electronics.
