Direct Visualization of Zinc Oxide Domains and Interfaces in Natural Rubber Vulcanizate by Nanomechanical Mapping

Abstract:

The particles of zinc oxide are distinguished from the other additive particles in natural rubber vulcanizate by AFM nanomechanical mapping. The results show that the size of zinc oxide particles is mostly less than 100 nm. Young’s modulus of zinc oxide particles in natural rubber matrix is 55.6 ±5.2 MPa, and that of interface is 16.6 ± 1.5 MPa. The width of the interface is 18±9.2 nm for the NR vulcanizate. This technique for direct visualization of ZnO particles domains and interfaces should open a new direction for studies directed at the elucidation of factors that control the domains, boundaries, structures and properties of particles in composites.
