Effects of chain flexibility on polymer conformation in dilute solution studied by Lattice Monte Carlo simulation

Article Abstract:

Monte Carlo simulation model was used to investigate the effects of chain flexibility on the conformation of homopolymer chains in dilute solution. The analysis indicates that the orientation of polymer chains under confinement is determined by the conformation entropy loss and a comparison with regards to chain flexibility and quasi-quantitative boundary of the freely jointed chain (FJC) model and the wormlike chain (WLC) model was used to describe the polymer sizes.

A self-consistent field theory study on the morphologies of linear ABCBA and H-shaped (AB)(sub 2)C(BA)(sub 2) block copolymers

Article Abstract:

A combinatorial screening technique based on the self-consistent field theory, is applied to study the equilibrium morphologies of linear ABCBA and H-shaped (AB)(sub 2)C(BA)(sub 2) block copolymers in two dimensions. The results would help in the design of block copolymers with different microstructures.

Equilibrium dynamics of an associating polymer melt in narrow slits by computer simulation

Article Abstract:

The dynamics of a coarse-grained model of a melt of polymer chains with associating terminal groups are studied with the help of molecular dynamics simulation. The strong attraction forces between the walls of the model form an aggregation structure with very long relaxation times.
