Vulcanization kinetics of graphene/styrene butadiene rubber nanocomposites

Vulcanization and the Properties of Rubber

Rubber is composed of long stringlike polymer molecules, which are pinned together at random points by crosslinks. As the density of crosslinks is increased, the molecules get localized and the system undergoes a phase transition from a liquid to an amorphous solid state. The elastic properties of the resulting solid are very different from those of metals, and are primarily due to changes in t...

effect of the compatibilizer upon the properties of styrene-butadiene rubber organoclay nanocomposites

nanocomposite vulcunizates based on styrene-butadiene rubber (sbr), organoclay and a conventional sulfur curing system were prepared by melt blending process in an internal mixer. in order to study the effects of the type of interfacial compatibilizer on the properties of sbr and clay nanoparticles,three types of compatibilizers, maleic anhydride grafted ethylene-propylene diene rubber (epdm-g-...

Cellulose Based Rubber Nanocomposites

This chapter gives an introduction on the general aspects of cellulose, natural rubber and their bionanocomposites. A brief literature review on what has been done so far on the cellulose, natural rubber nanocomposites research area is also included in this chapter. This chapter also describes the structure, properties and characterization of cellulose as a biobased nanomaterial in natural rubber.

Rubber Clay Nanocomposites

Natural rubber-clay nanocomposites

The mechanical properties of non-vulcanized natural rubber and dialyzed natural rubber-clay nanocomposites have been studied by uniaxial deformations to evaluate the reinforcement efficiency of the clay. We show that while non-rubber molecules contribute to auto-reinforcement, removal of these molecules improves significantly the performance of clay as reinforcement agent. These mechanical prop...
