Investigation of π stacking functionalization of carbon allotropes for RH sensing

Abstract

This paper is focused on the noncovalent functionalization of CNT by π stacking of molecules for relative humidity (RH) sensing. This type of functionalization is not used frequently, but it potentially offers a simple way how to control the level of functionalization of the carbon allotropes. The base idea is to stack the molecules with base hexagonal carbon structure on the carbon allotropes like carbon nanotubes or graphene. This paper deals with experiments with different materials with carbon hexagonal structure, which can be able to do π stacking interaction and also can be able to react on air relative humidity.
