Implication

Theoretical modeling reveals a universal graphitic potential across carbon nanotubes and buckyballs, simplifying van der Waals calculations and supporting peapod formation.

Key Points

To calculate the interaction potentials between carbon nanotubes and buckyballs to establish cohesive properties and determine a generalized analytical formula for graphitic systems.
Modeled interactions between parallel carbon nanotubes and between C60 molecules and nanotubes using continuous atomic surface distributions and Lennard-Jones potentials.
Derived tube-C60 interaction constants from graphene-graphene and C60-C60 parameters using dispersion force averaging rules.
Calculated cohesive energy per unit length, compressibility, and equilibrium separation distances as a function of tube radius.
Binding energy for C60 was significantly higher inside a nanotube than on its exterior or mouth, peaking at spherically capped ends.
Potential energies for all tested configurations—including tube-tube, C60-C60, C60-tube, and graphene interactions—collapsed onto a single universal curve when plotted with reduced parameters.
Calculated binding energies aligned with experimental transmission electron microscopy observations of carbon peapod formation.
