Synthesis and characterization of polyurea nanocomposites

Polyurea nanocomposites have attracted increasing attention. In this article, in order to study the thermal properties and mechanical properties of polyurea composites, polyurea nanoparticles with different content of silicon carbide (SiC) nanoparticles (0.7wt%, 1.5wt% and 2.5wt%) were prepared via in-situ polymerization method. Using XRD,FTIR, SEM, TGA and tensile testing machine to characterize and analyze the surface morphology, structure, thermal and mechanical properties of polyurea nanocomposites. The results obtained from this study showed that the thermal stability and mechanical properties of polyurea composites as compared to pure polyurea can be improved by adding nano-SiC.
