Amine functionalized Graphene/polydimethylsiloxane/polyisoprene nanocomposite

The objective of this research is to fabricate amine functionalized graphene composites based onpolydimethylsiloxane (PDMS)/polyisoprene (PI) and to characterize the gauge factor of the composites forthe use of strain sensors. The fabrication of amine functionalized graphene /PDMS/PI composites canbe accomplished by simple sonication and micro molding processes. We found that the measuredgauge factors strongly depend on the concentration amine functionalized graphene in the composites.Obtained gauge factor of the amine functionalized graphene/PDMS/PI composite strain sensor reachedabout 242 at a amine functionalized graphene concentration of 2.37 vol.%, which was measuredwithin a strain range of 2%.
