Effect of modified graphene and carbon nanotubes on the thermal properties and flammability of elastomeric materials

The paper presents the test results of the effect of modified graphene and multi-wall carbon nanotubes on the thermal and mechanical properties and flammability of acrylic rubber and styrene-butadiene rubber. The rubbers were cross-linked with the use of organic peroxide. Based on the test results obtained by optic and AFM methods, a relationship between the surface morphology of the nanocomposites obtained was presented. By means of thermal analysis methods (TG, DTG, DTA) and a micro-calorimeter, it has been found that the nanofillers used considerably increase the thermal stability and decrease flammability of the nanocomposites. The mechanical properties of the elastomeric materials obtained depend on the type and content of nanofiller.
