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 %.
Claims28
A carbon nanocapsule-layered silicate hybrid, comprising:
- a plurality of carbon nanocapsules;
- and
- a plurality of layered silicates;
- wherein the carbon nanocapsules and the layered silicates are physically mixed and mutually dispersed to exhibit a homogeneous dispersion phase, wherein a weight ratio of the carbon nanocapsules to the layered silicates is about 1:10 to 10:1.
A method for preparing a carbon nanocapsule-layered silicate hybrid, comprising:
- providing a plurality of carbon nanocapsules having a spherical shape;
- providing a plurality of layered silicates having a platelet-shape;
- and
- mixing the carbon nanocapsules and the layered silicates by a physical process for exerting a shear force such that the carbon nanocapsules and the layered silicates are mutually dispersed into a homogeneous dispersion due to geometric shape difference, thus forming the hybrid, wherein a weight ratio of the carbon nanocapsules to the layered silicates is about 1:10 to 10:1.
