Abstract

Adsorption of a single homopolymer chain with bending stiffness on a homogeneous planar surface is studied theoretically in the framework of the lattice model and the generating functions approach. The stiffness is introduced by assigning a statistical weight to a trans-isomer (a straight segment) with respect to a gauche-isomer (a kink). This statistical weight is related to the bending energy εbend associated with a kink: k=exp(εbend∕kBT) and depends on the temperature but one can also treat k as a temperature-independent parameter. Both positive and negative values of the bending energy corresponding to stiff (εbend>0, k>1, positive stiffness) and “quasi-zigzag” (εbend<0, 0
