Abstract

We consider the lattice model for an ideal-linear polymer chain to mimic the conformations of the semi-flexible homo-polymer chain. The polymer chain is assumed to confine in the fairly small area, such that the flexible chain conformations are easily polymerized in the nano-area. It has been described using analytical calculations that such a situation may lead to interesting and distinct theoretical findings of the thermodynamics of semi-flexible homo-polymeric macromolecules where the macromolecules are confined in the nano-length scale. We also discuss the characteristics of the persistent length and the elastic force due to the nano scale confinement of an infinitely long ideal polymer chain.
