ABSTRACT:
A carbon nanocapsule-layered silicate hybrid is provided. Layered silicates (platelet-shaped) as a dispersant are mixed with carbon nanocapsules (sphere-shaped) by a physical process. The physically mixed hybrid exhibits a homogeneous dispersion phase due to the geometric shape inhomogeneity factor. Aggregation of carbon nanocapsules is thus avoided. The hybrid can be dispersed in a polar or non-polar solvent with a solid content of about 0.01-30 wt %.
