The noncovalent functionalization of CNT with ionic liquids is a consequence of the cation-[pi] interactions between ionic liquid and the CNT surface and also due to
van der Waals interactions [19].
Physical adsorption via hydrogen bond or
van der Waals interaction does not cause any considerable modification in CNTs [65, 66].
The RDG was used to analyse the interactions, which can be divided into medium- and longrange interactions based on the distance or into hydrogen bonding and electrostatic and
van der Waals interactions according to the type of bond.
Furthermore, unlike the Coulombic interactions, the magnitudes of binding do not decrease in magnitude with the binding of CPP because the strength of hydrophobic and
van der Waals interactions remains relatively constant.
In this context, the
van der Waals interactions had to be also analyzed.
The results confirmed that
van der Waals interaction between the [O.sub.1]-[O.sub.2] atoms.
Ionic liquids are salts with melting points below 100 degrees Celsius, and represent a new class of non-molecular liquid materials with unique property profiles due to a complex interplay of Coulombic, hydrogen bonding, and
van der Waals interactions. Here chemists from universities and companies around the world show how to exploit some of these qualities to perform chemical reactions that are less damaging to the environment than conventional processes.
