Abstract

We extend earlier work that gave exact results for the thermodynamics and size parameters of a confined polymer to the case where the monomers have complex structure. The only restriction on the complex monomers is that they be composed of a linear sequence of sub-monomers, each of which occupies one site on the lattice. The complex monomers can contain both rigid and flexible parts. For ease of understanding, we first treat the case of a square (2-d) lattice. Then the cubic lattice (3-d) is treated. As before the confining walls can be both chemically and physically rough, the attraction energy of sub-monomers for the lattice sites can be different for each lattice site, and importantly can be different for each sub-monomer. There is no restriction on the number of, or the linear sequencing of, the chemically different complex monomers that constitute a polymer chain. Our results have application to a confined polymer in solution as found in polymer chromatography as well as to adsorption/absorption of polymers onto/into nano-particles.
