Reinforced polymers are of a great interest since the individual properties of the initial materials can be combined, resulting in a new hybrid material with better properties. Carbon nanotubes are popular polymer filler and reinforcing agent. They enhance the mechanical strength and corrosion resistance.
We performed first-principles DFT calculations of the covalent and noncovalent sidewall functionalization of metallic (6,0) and semiconducting (10,0) single-walled carbon nanotubes (SWCNTs) via the attachment of two aromatic diisocyanates: 4,4’-methylene diphenyl diisocyanate (MDI) and toluene-2,4-diisocyanate (TDI).
In this work, we focus on the structural rearrangements of the diisocyanates molecules covalently attached to the SWCNT(10,0) surface at the finite temperature, using the Car-Parrinello molecular dynamics (CP-MD) scheme.
