Hybridized nanoparticle strategy for graphene oxide based materials can effectively improve the mechanical property of their nanocomposites. Silica nanoparticles have a spherulite-like morphology, which can absorb on the surface of graphene oxide (layered morphology) under suspension solution system. In this study by Masoud Jamshidi and colleagues, the Ruoff phenomenon indicates that nanoparticles with different dimensions can improve dispersion of each other in polymers and enables the graphene oxide to disperse in nitrile rubber, thus improving the mechanical property and rubber elasticity.

Carboxymethyl cellulose loading can be used as a strategy to increase the hydrophilicity of polycaprolactone matrices. It is possible to tailor the water affinity of the matrix by modifying the content of this additive. Besides, the composites do not show a cytotoxic effect, so they are promising for biomedical applications.
