Thermod ynamic p roperties of carbon chiral na notubes a nd their dep endence o n molecular diameter

The study of the properties of nanotubes for physical and chemica l applicatio ns has yielded many hig hly useful a nd effective results in di fferent areas of science. The struct ure of a sing le-wall car bon nanotub e is determ ined by the orientation of the hexagonal ring of carbo n atoms in the honeycomb lattice relative to the nanotu be's axis. I n this study the relationship betw een some of thermodynamics prope rties such as thermal capacity (ΔCv ) , entropy (ΔS) , energy (ΔE ) , enthalpy(ΔH) , Gibbs free energy (ΔG) of ۱۴ different type of carbo n chiral nano tubes in co ntrast to their diameter are presented [۱-۴].
