Physisorption on graphene

In the previous chapter it has been shown that the H2$-$C$_{sp^2}$ pair potential can be parametrised on simple H2$-$PAH models. Such a potential has been used to evaluate the hydrogen interaction with different PAH structures and the rest have been extrapolated towards graphene platelets. The still remaining important questions are: How does the temperature influence the weak H2$-$sorbent interaction ($\le$10 kJ$\,$mol$^{-1}$) and how can the H2$-$H2 interactions be taken into account. The following chapter is intended to answer these questions and to give an example how the mathematical machinery described in Chapter 1 works in practice. The systems investigated in this chapter are graphene monolayer and graphene slit pores confined with different graphene interlayer distance.
