Reactive compatibilization effect of graphene oxide reinforced butyl rubber nanocomposites

Graphene Oxide Reinforced Poly(vinyl Alcohol) Nanocomposites

The first major success of polymer nanocomposites, where the filler has at least one dimension in the nanoscale, was reported by Kojima, Usuki et al. [1] from the Toyota Central R&D group. They demonstrated that nylon6/clay nanocomposites showed significant improvement in the mechanical and the thermal properties. Since then, works on the polymer nanocomposites have been conducted on a wide var...

Cellulose nanocrystal reinforced oxidized natural rubber nanocomposites.

Natural rubber (NR) latex particles were oxidized using KMnO4 as oxidant to promote the insertion of hydroxyl groups in the surface polyisoprene chains. Different degrees of oxidation were investigated. Both unoxidized and oxidized NR (ONR) latex were used to prepare nanocomposite films reinforced with cellulose nanocrystals (CNCs) by casting/evaporation. The oxidation of NR was carried out to ...

Compatibilization of immiscible polymer blends using graphene oxide sheets.

By taking the advantage of the unique amphiphilic structure of graphene oxide sheets (GOSs), we develop here a new and effective strategy for compatibilizing immiscible polymer blends. With the incorporation of only 0.5 wt % GOSs into immiscible polyamide/polyphenylene oxide (PA/PPO, 90/10) blends, the droplet diameter of the dispersed minor phase (PPO) is dramatically reduced by more than 1 or...

Reactive Processing of Silica-reinforced Tire Rubber

High Performance Graphene Oxide Based Rubber Composites

In this paper, graphene oxide/styrene-butadiene rubber (GO/SBR) composites with complete exfoliation of GO sheets were prepared by aqueous-phase mixing of GO colloid with SBR latex and a small loading of butadiene-styrene-vinyl-pyridine rubber (VPR) latex, followed by their co-coagulation. During co-coagulation, VPR not only plays a key role in the prevention of aggregation of GO sheets but als...
